Through qualitative and quantitative calculations, it was found that the landslide in the survey area is in a basically stable to unstable state. Through stability calculation analysis, in the natural state, the four profiles L1, L2, L3, and L4 are in a basically stable state;Under saturated conditions, all four profiles are in an unstable state. Under the rainstorm condition, the landslide may cause overall deformation, instability and sliding. The main threat of landslides is a total of 10 people, including 3 households living in the northern part of the slope and forest firefighters, with a potential economic loss of about 296,000 yuan. The hazard level of landslide geological hazards is Level III. It is recommended to improve the group 展开更多
