Introduction of Beijing-Guangzhou high-speed rail line?

Beijing-Guangzhou high-speed railway (also known as Beijing-Guangzhou Passenger Dedicated Line, Beijing-Guangzhou Passenger Dedicated Line and Beijing-Guangzhou High-speed Railway) is one of the high-speed passenger dedicated lines being operated in China, with the operating mileage ranking first in the world, with a total length of 2,294 kilometers.

Beijing-Guangzhou high-speed railway consists of Beijing-Shijiazhuang high-speed railway, Shiwu high-speed railway and Wuhan-Guangzhou high-speed railway. It starts from Beijing West Railway Station, passes through six provinces and cities of Beijing, Hebei, Henan, Hubei, Hunan and Guangdong, and ends at Guangzhou South Railway Station, with a total length of 2,298 kilometers and 36 stations, with a design speed of 350 kilometers per hour and an operating speed of 3 10 kilometers per hour. Along the way, there are stations such as Shijiazhuang Station, Zhengzhou East Station, Wuhan Station and Changsha South Station.

brief introduction

The Beijing-Guangzhou high-speed railway line connects Bohai Economic Circle, Central Plains Economic Zone, Wuhan Metropolitan Area, Changsha-Zhuzhou-Xiangtan Urban Agglomeration and Pearl River Delta Economic Zone, and is divided into three sections: Beijing to Shijiazhuang, Shijiazhuang to Wuhan, and Wuhan to Guangzhou. Among them, Wuhan-Guangzhou section, Shiwu section and Zhengzhou-Wuhan section have been opened for operation respectively.

The construction of Beijing-Guangzhou high-speed railway began in 2005, and the whole line is divided into three sections. The southern section of Wuhan-Guangzhou high-speed railway was first opened to traffic on February 26th, 2009. The Shiwu Passenger Dedicated Line in the middle section is divided into two parts with Zhengzhou East Station as the boundary. Zhengzhou-Wuhan section was put into operation on September 28th, 20 12, Shijiazhuang-Zhengzhou section and Beijing-Shijiazhuang passenger dedicated line in the north section were put into operation on February 26th, 20 12.

On February 26th, 20 12 and 12, the Beijing-Guangzhou high-speed railway was put into operation. The travel time of the high-speed train from Beijing to Guangzhou was shortened to 8 hours. At the same time, it also effectively promoted the new development along the railway.

In 20 13, the "four vertical and four horizontal" trunk lines of China high-speed railway will be fully connected, the high-speed railway operation map will be greatly refreshed, and the overall high-speed railway operation line will also make new breakthroughs. The Beijing-Guangzhou high-speed railway artery connects Bohai Economic Circle, Central Plains Economic Zone, Wuhan City Circle, Changsha-Zhuzhou-Xiangtan City Group and Pearl River Delta Economic Zone.

The southern end of the Beijing-Guangzhou high-speed railway is connected with the Guangzhou-Shenzhen-Hong Kong high-speed railway, which constitutes the passenger dedicated line from Beijing to Hong Kong in the "four vertical and four horizontal" railway express passenger passage planned in the Medium and Long-term Railway Network Planning. It will form a high-speed passenger corridor that runs parallel to the Beijing-Guangzhou Railway, runs through the north and south of China and has the widest radiation range.

There are 2,294 kilometers from Beijing to Guangzhou on the Beijing-Guangzhou line, and it takes more than 20 hours to travel from Beijing to Guangzhou by Z35. It takes only 8 hours to travel from Beijing West to Guangzhou South by G79 train. In the future, the Beijing-Guangzhou high-speed railway will also connect with Hong Kong, and it is expected that the Shenzhen-Hong Kong high-speed railway will be opened on 20 17.

National examination and approval

In 2005, the State Council approved the National Medium and Long-term Railway Network Planning, and planned to build a "four vertical and four horizontal" railway high-speed passenger transport network and a new railway "Golden Cross".

Among them, the Beijing-Guangzhou Passenger Dedicated Line, one of the north-south traffic arteries, also known as Beijing-Shijiazhuang-Zhengzhou-Wuhan-Changsha-Guangzhou, intersects with the Xuzhou-Zhengzhou -Xi 'an-Lanzhou high-speed railway, one of the east-west traffic arteries, at Zhengzhou East Station, becoming the first high-speed rail hub with a speed of more than 350 kilometers per hour in China. Beijing-Guangzhou high-speed railway will also meet Shanghai-Chengdu high-speed railway and Shanghai-Kunming high-speed railway at Changsha South Station in Wuhan.

The longest vertical axis of "four verticals and four horizontals"-Beijing-Guangzhou high-speed railway passenger dedicated line will shorten the driving distance from Beijing to Guangzhou from 20 hours to 8 hours. The Wuhan-Guangzhou section of the special line started in June 2005 and was opened to traffic at the end of 2009. The section from Beijing to Shijiazhuang was officially opened in June 20 12.

After 1964, Japan built the world's first high-speed passenger dedicated line with the speed of 2 10km/h, France, Germany, Spain, Italy, South China, Taiwan Province Province of China and other countries and regions successively built high-speed passenger dedicated lines, with the design speed ranging from 2 10km/h to 230260300 km/h. 1May, 985, UIC Expressway Department's opinion in the data of Development Trend of Design Technology for New Lines with Speed of 200 ~ 300 km/h (Part I) (20065438+0 65438+1October 25th) is that the speed target value of newly-built high-speed railway is 300 km/h. ..

After the opening of the whole line, the whole journey from Beijing to Guangzhou was shortened to about 8 hours.

The Beijing-Zhengzhou section of Beijing-Guangzhou high-speed railway was officially put into operation on February 26th, 20 12. It is connected with the Zhengzhou-Wuhan section and Wuhan-Guangzhou section that have been put into operation before, realizing the longest high-speed railway in the world. It takes only 8 hours from Beijing to Guangzhou at the earliest.

Beijing-Guangzhou High-speed Railway Passenger Dedicated Line (Beijing-Guangzhou High-speed Railway) is a high-speed railway with passenger transportation as the main part. The project starts from the capital Beijing in the north and ends in Guangzhou in the south, with a total length of 2,298 kilometers and a design speed of 350 kilometers per hour. By the end of 2065,438+02, the running speed was reduced to 365,438+00 kilometers per hour. This passenger dedicated line is one of the "four vertical and four horizontal" passenger dedicated line networks in China. After the passenger dedicated line is opened to traffic, the Beijing-Guangzhou railway will realize the separation of passenger and freight.

Road section composition

Jingshiduan

The Beijing-Shijiazhuang section of Beijing-Guangzhou Passenger Dedicated Line is 28 1 km, including 229.5 km in Hebei, with an estimated total investment of 38.49 billion yuan and a design speed of 350 km/h. There are 7 stops along the way-Beijing West Railway Station, Zhuozhou East Railway Station, Gaobeidian East Railway Station, Baoding East Railway Station, Dingzhou East Railway Station, Zhengding Airport Station and Shijiazhuang Station. Around 20 15, the starting station of Beijing-Guangzhou high-speed railway will be changed from Beijing West Railway Station to newly-built Beijing Fengtai Station.

The Beijing-Shijiazhuang section of the Beijing-Guangzhou Passenger Dedicated Line was started on June 7, 2008, and put into operation simultaneously with the Zheng Shi section of the Beijing-Guangzhou Passenger Dedicated Line on February 26, 2002, marking the completion of the Beijing-Guangzhou Railway Passenger Dedicated Line.

Fifteenth section

The Shiwu section of Beijing-Guangzhou Passenger Dedicated Line leads from Shijiazhuang Station, crosses Yin Qing Expressway in the south, passes through Yuanshi County West, Gaoyi West and Lincheng East, passes through Xingtai East in Hebei, Handan East in Hebei, Anyang East in Henan, Hebi East in Henan and Xinxiang East in Henan, crosses Zhengzhou East Station in the west of Zhengzhou East Fourth Ring Road, passes through xinzheng city East, Xu Changdong and Beijing-Guangzhou Railway in the north of Linying County, and passes through Luohe West, Ming and Qing Dynasties. Crossing the Huaihe River and Xinyang, passing through the west side of Dongzhai National Nature Reserve, entering Hubei, passing through the east side of Dawu County Mineral Economic Development Zone in the north of Xiaogan City and the west side of Meidian Reservoir, passing through Hengdian East Station to Wuhan Tianxingzhou Yangtze River Bridge, and finally introducing Wuhan Station, the starting station of Wuhan-Guangzhou section of Beijing-Guangzhou Passenger Dedicated Line, 202.642km in Hebei Province and 506.862km in Henan Province, 136558.

There are 13 intermediate stations in the 15th section, which are Gaoyi West Station, Xingtai East Station, Handan East Station, Anyang East Station, Hebi East Station, Xinxiang East Station, Zhengzhou East Station, Xuchang East Station, Luohe West Station, Zhumadian West Station, Minggang East Station, Xinyang East Station and Xiaogan North Station from north to south, among which Shijiazhuang Station, Zhengzhou East Station and Wuhan Station are the starting stations and Handan East Station. And reserve conditions for Xinzheng station. The overall goal of the construction of Beijing-Guangzhou passenger dedicated line is to reach the world-class level. Therefore, the target value of fixed facilities should focus on long-term development, leaving room for technological development, because once the fixed facilities are built, it is difficult to change. According to the research conclusion of transportation organization mode, the Shiwu section of Beijing-Guangzhou Passenger Dedicated Line will use mixed trains with different speeds in a certain period of time, that is, the trains running in Shiwu section of Beijing-Guangzhou Passenger Dedicated Line include slow trains, A-type overpass cars and B-type overpass cars, and the slow trains and A-type overpass cars run at a high speed level of more than 300 km/h, so the minimum running speed is the minimum running speed of B-type overpass cars, and the minimum running speed of trains running on Shiwu Passenger Dedicated Line should not be less than 250 km/h.

After the completion of the Shiwu section of Beijing-Guangzhou high-speed railway, it can be connected with Shijiazhuang-Taiyuan Passenger Dedicated Line, Zhengxi Passenger Dedicated Line, Xú Zhēng Passenger Dedicated Line and Wu He Passenger Dedicated Line, forming an efficient, convenient, fast and safe passenger transport network, effectively releasing the transport capacity of the existing Beijing-Guangzhou railway, which is of great significance to improving the regional passenger and freight transport structure, accelerating the construction of China's rapid passenger transport network, expanding transport capacity and improving service quality. It will have a significant and positive impact on society, benefiting a large number of people and a wide range, meeting the travel needs of tourists from all walks of life, saving tourists' travel time, increasing employment opportunities and promoting the development of tourism.

On the west side of Zhengzhou East Railway Station, there is the Beijing Plaza running through the Beijing-Guangzhou Passenger Dedicated Line, and on the east side, there is the Xulanchang running through the Xu Lan Passenger Dedicated Line. The two events are arranged in rows, with 32 main lines, arrival and departure lines and 30 platforms. The total construction area is 392,000 m2, of which the station building area is 6.5438+0.5 million m2, the platform awning area is 78,000 m2, and the subway, tunnel and parking lot are * * * 6.5438+0.64 million m2, with a project investment of 7.50 billion yuan and a total construction period of 30 months.

Wu Guang part

Wuhan-Guangzhou section of Beijing-Guangzhou passenger dedicated line is one of the key construction projects in China during the 11th Five-Year Plan, which is of great significance to Guangdong, Hunan and Hubei. In order to balance the interests of the three places, the Ministry of Railways finally chose Changsha as the venue for the groundbreaking ceremony.

On June 23, 2005, the Wuhan-Guangzhou section of the Beijing-Guangzhou Railway Passenger Dedicated Line officially started construction. The Wuhan-Guangzhou section of the Beijing-Guangzhou Passenger Dedicated Line is 968 kilometers long, with an investment of 93 billion yuan and a construction period of 4.5 years. On February 26th, 2009, the whole line was completed and opened to traffic.

There are altogether 6 stations/kloc-0 along the Wuhan-Guangzhou section of Beijing-Guangzhou Passenger Dedicated Line, namely Wuhan Station, Xianning North Station, Chibi North Station, Yueyang East Station, Miluo East Station, Changsha South Station, Zhuzhou West Station, Hengshan West Station, Hengyang East Station, Leiyang West Station, Chenzhou West Station, Lechang East Station, Shaoguan Station, Yingde West Station, Qingyuan Station and Guangzhou North Station. At the same time, the construction conditions of Wulongquan Station are reserved. Among them, Wuhan Station, Changsha South Station and Guangzhou South Station are the starting stations, and other stations are intermediate stations.

The completion of the Wuhan-Guangzhou section of the Beijing-Guangzhou Passenger Dedicated Line has greatly eased the pressure of mixed passenger and freight transportation in the southern section of the Beijing-Guangzhou Railway for many years, and it is connected with the Shanghai-Kunming high-speed railway under construction, the completed Guiguang high-speed railway, the Nanguang high-speed railway and the Guangzhou-Shenzhen-Hong Kong high-speed railway.

It is of great significance to improve the railway passenger and freight transport structure in Central South China, accelerate the construction of China's rapid passenger transport network, expand transport capacity and improve railway service quality. It connects the Pearl River Delta Economic Zone in Guangdong, Changsha-Zhuzhou-Xiangtan Economic Zone in Hunan and Wuhan Economic Zone in Hubei, and has made positive contributions to the labor flow and industrial transfer among these three regions. As the forerunner of China's long-distance high-speed railway, it also provides extremely valuable experience for the construction and operation of other high-speed railways.

Engineering difficulties

The construction is difficult. The Zhengzhou-Wuhan section of the Beijing-Guangzhou high-speed railway crosses the Beijing-Hong Kong-Macao Expressway and the Shanghai-Han Rong express passenger railway, so the construction safety is very difficult. Mulan tunnel is 4745 meters long, with weak rock mass, developed cracks and broken rock mass. It is a shallow tunnel under gully, and water inrush often occurs during tunnel excavation. The total length of Huanglongsi tunnel is 87 15m, and the buried depth of the tunnel is generally 100-200m, and the maximum buried depth is about 335m. The surface water system is only developed in some river valleys, and there are three northeast and nearly east-west streams in the cave. There are mainly five large and small fractures in the scope of the tunnel body, and the fracture zone is structural breccia, which is not cemented, has good water conductivity and strong water yield, and the maximum water inflow is 187m3/d, so the construction risk is great.

High technical standards. On the basis of other high-speed railway technologies such as Beijing-Tianjin and Wuhan-Guangzhou, we digested and absorbed them, created the management technology of CA mortar raw material comparison reference sample, mastered the construction technology of CA mortar pouring and effective segregation control, optimized the design and construction technology of wide and narrow joints and lateral stops of ballastless track, and built the world's first CRTs slab ballastless track in mountainous areas and long tunnels, which indicates that China has mastered a complete set of key technologies for building CRTs slab ballastless track and long tunnels in mountainous areas.

There are many professional interfaces. The construction process involves subgrade, bridge and culvert, tunnel, ballastless track, precision measurement, integration of electricity and electricity, station building construction, customer service information and other majors, with strong professionalism and complicated procedures. The conversion between technology and specialty is frequent and complicated, involving the conversion between offline and track engineering, the conversion between in-station and post-station engineering, and the conversion between main and auxiliary engineering. These transformations involve the cooperation between different interfaces, and there is great pressure to ensure a safe, orderly and smooth connection.

Environmental protection requirements are high. New energy-saving and environment-friendly building materials are widely used in the station buildings, and all the stations and yards adopt pillar-free awnings, with good lighting performance, complete and transparent venue functions, simple and smooth passenger access, ticket purchase, waiting, getting on and off passengers, and reasonable connection with highways and other modes of transportation to realize "zero distance" transfer. The design of "replacing road with bridge" is widely used, and the ratio of line, bridge and tunnel is 865,438+0%, which is beneficial to ensure the quality of line and safe operation, and save a lot of land resources.

run quickly

The Beijing-Guangzhou high-speed railway 20 12 12 with the longest operating mileage in the world was officially completed on February 26th, and the time from Beijing to Guangzhou was shortened to about 8 hours. The analysis pointed out that the Beijing-Guangzhou high-speed railway is of great significance, which will not only become a new engine to promote economic development along the route, but also have an important impact on the air transport industry and express logistics industry, and will also promote the "high-speed rail tour" and promote the development and transformation of the tourism market along the route. The "new artery" running through China's economy

With a total length of 2,298 kilometers, Beijing-Guangzhou high-speed railway is the longest running high-speed railway in the world. Experts said that the opening of the Beijing-Guangzhou high-speed railway will obviously boost the regional economy along the line and will play a "backbone" role in the national "four vertical and four horizontal" high-speed railway network.

Chen Yabing, one of the line designers and chief engineer of Zheng Jing Project of the Third Railway Survey and Design Institute, told China News Service that in the existing "four verticals and four horizontals" railway network planning, the Beijing-Guangzhou high-speed railway is an important "one verticals" running through the north and south, starting from Beijing, passing through Shijiazhuang, Zhengzhou, Wuhan and Changsha to Guangzhou, covering major economic zones such as North China, South China and Pearl River Delta in China, especially through densely populated economic centers such as Beijing, Wuhan and Guangzhou.

The railway department said that the completion of the whole railway line provided an important opportunity for 28 cities along the line to improve their speed economy. It saves a lot of time for economic circulation and personnel flow, which means winning speed and making a lot of profits for related enterprises.

The analysis points out that, on the one hand, the rapid flow of population is bound to intensify various economic activities. After the Beijing-Guangzhou high-speed railway runs through, a large city circle will be formed around each city, and economic exchanges with other cities will be accelerated. On the other hand, high-speed rail will accelerate industrial transformation and upgrading and industrial transfer in economically active areas such as the Pearl River Delta.

Or trigger "air-ground confrontation" again.

The completion of the Beijing-Guangzhou high-speed railway will have an important impact on the air transport industry. Tickets for several short-haul routes are discounted, and some airlines are considering canceling the routes that have been severely hit by the Beijing-Guangzhou high-speed railway. Before the project, "cabbage price" appeared on several short-distance routes. Nanfang Daily reported that the ticket price from Wuhan to Beijing was as low as 20%, and the flight price directly penetrated 200 yuan.

The analysis pointed out that although the speed of the plane still has a greater advantage than the high-speed rail, considering the time spent in the process from the city to the airport, security check, baggage claim to the destination, and the frequency of flight delays, the advantage of aviation is being eroded. The industry expects that the diversion of passengers from Beijing-Guangzhou high-speed railway will have an impact on the aviation industry along the route, especially short-haul flights.

Liu Weimin, director of the Aviation Law Research Center of China Civil Aviation Management Cadre College, analyzed in an interview with a reporter from China News Service that the Beijing-Guangzhou high-speed railway, because of its faster speed and convenient commuting between the city and the railway station, will inevitably divert some passengers and impact the airline business, but at the same time, it will also integrate the airline network, improve efficiency and management, form a reverse mechanism, or provide a new round of transformation opportunities for the aviation industry.
