Abstract: Slope stability is one of the important issues in geotechnical engineering. Based on rock strength indicators and finite element method, this paper analyzes the stability of slopes. Firstly, the definition and calculation methods of rock strength indicators, including compressive strength, tensile strength and shear strength of rocks, are introduced. Then, a numerical model of the slope is established using the finite element method. Through the stress-strain analysis of the slope under different conditions, the stability analysis results of the slope are obtained. Finally, the feasibility and effectiveness of the method are verified by analyzing a slope in an actual engineering project.
