Numerical Analysis of the Excavation of Deep Pit Based on Mohr-Coulomb Failure Model

Abstract:

The Principles of Mohr-Coulomb failure model and hardening and rate dependence are dealt with in detail. Based on Mohr-Coulomb failure model with isotropic hardening, numerical analysis is conducted . The results calculated show that the horizontal displacement and moment of the continuous wall, and the subsidence of surface outside the pit agree with the objective laws during the excavation. The method adopted and those results gained by numerical method may provide reference to engineering practice.
