Abstract

This paper applies the definite difference calculation programs FLAC to the numerical simulation of the foundation pit excavation and the construction of soil nailing wall in a Huan'an project.It then examines the changing law of the soil displacement,stress field and the mechanical force that the soil nail bears in the process of foundation pit excavation and soil nail support.The result of numerical simulation is similar to the actual data obtained from construction,which indicates it is effective to adopt the numerical method to simulate the foundation pit excavation.
