The application of finite element method in studying the height under ultimate load of soil-nail support;

To cope with the deformation of the composite soil-nail supported super large foundation pit during excavation for Shanghai Oriental Art Center, the 2-D finite element method is adopted to analyze the force on the composite soil-nail support structure and the lateral deformation during shallow excavation of the pit.

The safe and economil quality of soil nail wall support can be increased.

Combined with engineering in Pingding county,it analyzes cause of failure applying for soil nail wall support according to geological condition of side slope,introduces new treatment plan,and summarizes points on analyzing and treating stability of side slope.
