Abstract :
The article took Guansheng landslide as the research object, based on the analysis of the deformation data and geological data, implemented the geotechnical test and real-time monitoring, by choosing the limit equilibrium method and strength reduction method to evaluate the safety factor in different rainfall conditions, to predict the warning threshold and failure mode of the landslide. The result shows that twice continuous rainstorms will cause the water level rising rapidly, saturated the landslide soil, decline the shear strength seriously, cause the destruction.
