Abstract

For the foundation pit near the existing urban rail transit,to ensure the normal operation is the key of the project design.Based on the complex surrounding environment of foundation pit,combined with the engineering geological and hydrogeological conditions,foundation pit excavation depth,the author uses a variety of support types.Through calculation of Lizheng software and finite element analysis,and the engineering analogy,it is proved that the support types can meet the foundation pit excavation and safe use,and ensure the normal operation of urban rail transit.

- groundwater control,
- supporting structure,
- finite element analysis
