High rock slope affects the safety of people's life and property,and its deformation and failure mecha-nism and mechanical mode are very complicated.Taking a consequent high rock slope as the research object,this paper analyzes the main factors affecting the stability of the slope based on detailed engineering geological investiga-tion,and analyzes the working conditions under heavy rain through the structure surface strength reduction.By u-sing qualitative analysis method of stereographic projection,and quantitative analysis method of limit equilibrium,it is obtained that the failure mode of the slope is mainly three-dimensional wedge block partial buckling and instabil-ity along the structural planes.Finally,the stability is calculated and analyzed,so as to provide reference for the sta-bility evaluation of slopes formed by different combinations of structural planes.
