According to the deep foundation pit of a spatial dimension in Shijiazhuang, the retaining and protection structure of pile and anchor cable is selected because of property of the soil layer. The interaction between the support system and the surrounding buildings is analyzed by the finite difference method, on this basis, according to the deformation of surrounding environment and the stability requirement of slope, the deep foundation pit is made zoning supporting design. When there is a building on the outside of foundation pit wall and the building is located in the middle side of the slope wall, the effect of building on horizontal displacement of foundation pit is mainly happened in the middle of the slope wall, and the range is (0.22~0.78) L (L is the length of the foundation pit) or 1.85A (A is the length of the building along the direction of the pit). The settlement and different settlement of the building foundation can be controlled by increasing the stiffness of the retaining structure, such as increasing the diameter of pile or reducing the spacing of pile. When reducing the diameter of pile or increasing the spacing between the piles in the west side of the slope, the deformation and different deformation of the area are obviously reduced, so as to meet the requirements for the deformation of the underground pipelines outside the slope wall.
