Abstract:

Based on digital elevation model (DEM)，the slope in Dingjiafen, Chuxiong was taken as an experimental research worksite to study the effect of rainfall on landslide occurrence and distribution by means of landslide rainfall threshold model(LRTM). The critical rainfall for a slope unit to generate a potential sliding was simulated combined with field investigation, monitoring data, main features of the slope rock and soil mass, topography and geomorphology, rainfall intensity and duration, underground water level and other factors. Results showed that the critical rainfall to cause a potential sliding varies in each slope. In different rainfall and groundwater level conditions, according to the simulation of LRTM the potential landslide position was mainly located below Chu-Meng highway, leading to a more than 80% agreement rate with the actual landslide position. Visual analysis and prediction of slope stability can be realized through LRTM, which provide an effective method for the forecast and analysis of rainfallinduced landslide.

Key words: rainfall threshold, landslides, slope stability
