Brief introduction of Longyou Grottoes in Zhejiang Province

A brief introduction to Longyou Grottoes in Zhejiang is as follows:

Xiaonanhai Stone Chambers, commonly known as Longyou Grottoes, are a group of underground stone chambers distributed in Xiaonanhai Town and the north bank of Qujiang River in Longhu Town, Quzhou City, Zhejiang Province. Caolong Village Head 16km in the east of Lake Town, 5 km in the west of Wengchuantou in Xiaonanhai Town, 5 km in the north of Tashi Town and the junction of Qujiang in the south.

The total number of stone chambers in Xiaonanhai is about 60. Among them, there are 25 Shiyanbei natural villages in Fancun, Hong Zhou, Xiaonanhai Town. The numerous stone chambers in Xiaonanhai and their peculiar structures have aroused people's enigmatic speculation, attracting countless Chinese and foreign tourists, experts and scholars, and literati to visit and inspect.

On March 5th, 20 13, Xiaonanhai Stone Room was announced by People's Republic of China (PRC) and the State Council as the seventh batch of national key cultural relics protection units.

The Scientific Value of Xiaonanhai Stone Chamber

Xiaonanhai Stone Chamber has excellent engineering exploration, engineering exploration, planning, design and construction level. It is a super-large underground building complex built in ancient China, which is of great significance to the history of underground architecture and the development and utilization of underground space in China and even in the world.

Supporting the rock surface at the top of the slope with columns ensures the stability of surrounding rock, which embodies the basic idea of modern underground engineering construction mechanics. The cross section of the column is triangular, and its long axis direction is parallel to that of the cavern, which is very consistent with the mechanical characteristics of the column structure. Setting "diagonal brace" at the top of the column is a very scientific structural form, similar to the beamless floor column in modern architecture. It is not only beneficial to the stability of the surrounding rock at the top of the cave, but also increases the aesthetic feeling.

Some columns are deliberately made into inclined columns, the inclination of which is consistent with the top of the slope, which is beneficial to the stability of the whole surrounding rock and the safety of the columns. Moreover, the roof of the stone room is very thin, with sandstone and clay rock on it. The material is not good and the column section is small. The project can be completed and preserved to this day. This is a special underground project.
