Abstract

The finite element method (FEM) approach was utilized in the analysis of jointed rock mass failure development in a large highway slope. Using FEM modelling, it was possible to investigate the formation of a basal failure surface within a highway slope as a direct result of deep excavation cutting. The modelling of FEM highlighted the importance of rock mass tensile strength and its influence on cutting-induced slope response. This paper demonstrates the ability of Shear Strength Reduction (SSR) analysis based on the FEM to model the scale effects of joint networks on the stability and failure mechanisms of slopes in rock mass. The results of the numerical analysis are consistent with the observed slope surface evidence.
