Open publisher page 0 citations

Abstract

Based on field geologic survey,the method of stereographic projection was adopted to analyze the potential failure mode of high rock slope in the sedimentary rock areas.According to the potential failure mode,the methods of limit equilibrium were applied to analyze the stability of the slope.A scheme of cutting the quarry slope with lower safety was putted forward.Meanwhile,FEM was also used to analyze and estimate the stability of the slope.It is considered that bedding plane is the worst structural plane affecting the stability of high rock slope in the sedimentary rock areas.As a result,it is a key point to survey and study.
