Parameter Susceptibility Analysis of the Shimen Landslide (Liaoning Province, China)

Abstract

GEO-SLOPE software was used to evaluate each parameter's contribution to the Shimen landslide susceptibility by single characteristic factor analysis. The research shows that the internal friction angle of the rock and soil mass have the greatest effect on the slope stability coefficient. Based on their effect on the slope stability, the most important parameters for landslide susceptibility, ranked in descending order, are the groundwater level, the cohesion, and the density of the quartzite. These research results can serve as a guide for future research on landslide control.
