Analysis of Failure Mechanisms of Guang Yang Highway Slopes in Jointed Rock Masses

摘要

This paper demonstrates the ability of Shear Strength Reduction (SSR) analysis based on the Finite Element Method (FEM) to model the excavations sizes effects of discontinuity networks on the stability and failure mechanisms of slopes in blocky rock masses. Through GuangYang highway slope in k3+980～k4+240, it shows how these mechanisms depend on joint network geometry and change with increasing slope height.
