摘要：
Strength reduction method was used to analyze the stability of weathering rock slope. The shear strength parameters of the rock slope material were successively reduced until slope equilibrium could no longer be maintained, and the safety factor of the weathering rock slope was obtained. The final failure state of this slope was composed of tensile damage and shear damage under earthquake. The shear strength parameter exercised a great influence on the slope safety. The slope safety factor was 1.0, so it should be reinforced treatment. Through comparative analysis, bolting method was chosen to solve this problem. Research result provides an important reference for similar projects.
