Abstract

Abstract

In this paper,one homogeneous soil pit of 10m deep is modeled by the software of FLAC 3D,the slope,which is supported by soil-cement mixied pile and composite soil nailing supporting structure is analyzed in detail by the ways of the horizontal displacement on the pit wall.Vertical displacement on the ground and on the bottom of the pit and the axial internal force of the soil nail.Finally,the regularity conclusion about the homogeneous soil pit which is supported by soil-cement mixed pile and composite soil nailing supporting structure is summarized,which provided references to the application of Pit supporting Engineering practice.
