Abstract: This paper selects a typical landslide site and investigates the basic conditions of the landslide. The triggering mechanism of the landslide is analyzed qualitatively from four aspects: the landslide structure, the weak plane, the groundwater infiltration, and the weakening of the rock and soil mass. The traditional classical transfer coefficient method is then used to quantitatively evaluate the stability of the landslide under the natural, the rainstorm and the earthquake conditions. The body is unstable, the factor of safety under the earthquake conditions is 1.017, and therefore is marginally stable condition. The stability analysis results of the landslide are basically consistent with the deformation history and qualitative analysis results. The qualitative and quantitative evaluation results confirm each other, which validates the accuracy of the evaluation results and provides a strong basis for the landslide mitigation and prevention measures.
