Numerical Simulation of Soil Nailing Wall in Deep Foundation Pit

Abstract

Based on finite difference method and Mohr-coulomb criteria, the numerical model of representative profile of a deep foundation pit was built. The excavation process and soli nailing retaining structure are simulated. The stability of retaining structures which meets the requirement of technical specification is verified by analyzing the displacement and stress. And the force mechanism of soil nailing and concrete surface is studied.
