  • Qiujialiang landslide of Zhouzhi county in Xi'an city is selected as the research object in this paper. In the detailed analysis of morphological characteristics, stratum lithology, material structure of landslide body and deformation features, the SEEP/W module and SLOPE/W module of the slope stability analysis software Geostudio are used for coupled calculation. The change of unsaturated seepage field in the slope body under the condition of rain infiltration is studied. The change of landslide stability under different rainfall intensity is discussed. The results show that besides topography, lithology and other geologic conditions, rainfall is the main inducing factors affecting landslide stability. The relationship among rainfall intensity, rainfall duration and landslide stability is also studied. The research results can provide a scientific basis for objectively evaluating the landslide stability under the condition of rainfall.
