Turbinate underground structure

Abstract

The invention discloses a turbinate underground structure. The turbinate underground structure is arranged in space below the ground. The angle alpha of a turbination is matched with the rock soil stress increase gradient. Main bearing force and construction support points are provided to the underground structure by a central stand column. The underground structure comprises a plurality of layers, and each layer is provided with a structural inner support. The structural inner supports, namely cross steel-concrete composite structures, are parallel to the main stress direction of the interiorof the rock soil. The outer structure of the underground structure is a cast-in-place reinforced concrete wall. The underground structure has the advantages that a reverse construction method is adopted, and accordingly, one-step construction or staged construction is achieved; in terms of stress conditions, construction difficulty, structural stability, structural extensibility and the like, theunderground structure is well attached to fixed laws of the underground space, stress requirements of the rock soil are met, high space development capability is achieved, and city underground spaceutilization efficiency can be well provided.

Description

technical field [0001] The invention relates to an underground space structure, belonging to the field of underground space structure design. Background technique [0002] With the development of cities, the utilization of urban underground space has become an important direction of modern urban development, and it is also the main direction of future urban development. There are more and more underground buildings and structures, more and more complex, and their functions are more and more diverse. However, most of the modern underground space structure design and construction still use the surface structure, which is nothing more than moving the entire ground building underground. This does not conform to the inherent laws of underground space, and it also brings many difficulties and challenges to the construction. [0003] The structure design of modern underground space mostly follows the surface structure, mostly cubic structure, but this does not coincide with the st...

However, most of the modern underground space structure design and construction still use the surface structure, which is nothing more than moving the entire ground building to the ground. This does not conform to the inherent laws of the underground space, and it also brings many problems and challenges to the construction.

[0003] The structure design of modern underground space mostly follows the surface structure, mostly cubic structure, but this does not coincide with the stress distribution of underground space. At the same time, the safety and stability of the side wall of the foundation pit during structure construction is also a difficulty and challenge in construction. Design a An underground structure that conforms to the laws of underground space can solve this problem
