Analysis of influencing factors and causes of landslide based on statistical simulation method

In this paper, the landslide area of Dalingong Mountain is taken as the research object. Based on the idea of Statistical simulation method, simplified calculation models of Bishop method and Fellenius method are constructed respectively to analyze the geotechnical parameters of landslide affecting stability in the landslide area of Dalingong Mountain. The shear strength factors that affect the stability of landslide soil mass are the friction angle φ and the cohesion force C of sliding surface. The influencing factors and causes of landslide formation are summarized. It provides the technical basis for avoiding and reducing the loss of geological disasters to the maximum extent, and also provides the basic guarantee for geological disaster prevention and reduction.
