| description | Basalt platform is a special type of landslide, however, its stability has received little attention before.This paper takes the Diyayuan landslide in Shengzhou city as the research object, and uses the method of three-dimensional numerical simulation to analyze and evaluate its stability.Then the rainfall recurrence period was determined based on the P-Ⅲ distribution curve, and the geotechnical software MIDAS was used to simulate the landslide stability and the 3D motion simulation platform DAN3D software was used to calculate the landslide impact range; finally, sensitivity analysis was carried out for the stability factors affecting the landslide The results show that different rainfall intensity has great influence on the stability of Diyayuan landslide.At this time, the stability coefficient of landslide is 0.946, the failure probability is 65.25%, and the maximum impact range increases by 36.83%; the angle of internal friction and rainfall are the main factors affecting the stability of Diyayuan landslide The analysis shows that the stability of basalt platform landslide is obviously correlated with the development of diatomite slip zone, joint and fissure surface, and the hysteresis of rainfall infiltration.The results of this paper can provide reference for the stability evaluation of similar landslide. |
