Landslide geological disasters pose a serious threat to people's lives and property and engineering construction, and in order to reduce the damage that can be caused by landslide geological disasters, it is necessary to make effective prediction of landslide geological disasters. The safety factor of slope is calculated by using the limit balance method and the intensity subtraction method respectively, and the stability of the landslide is analyzed comparatively. In this paper, a landslide in Taihu County is used as the research object, the calculation tool of Lizheng and FLAC3D software is used to calculate the safety coefficient of the landslide by using simplified Janbu method and strength reduction method respectively, and the stability of the landslide is evaluated according to the Landslide Engineering Survey Specification (GBT32864-2016), so as to compare and analyze the stability of the landslide. The results show that the computational analysis results of simplified Janbu method and strength reduction method are consistent with the calculation and analysis of the landslide stability, and the landslide is in an unstable state. %K 滑坡,理正软件,Janbu法,FLAC3D,强度折减法,稳定性分析
