Abstract: Loess Plateau is one of the most developed areas of geological disasters in China, and the shallow loess landslide induced by rainfall is the most typical. Taking Liulin County, a typical loess landform area, as an example. With the increase of rainfall in the study area, the area change, distribution location and expansion trend of the landslide deformation instability area are analyzed. The research shows that with the increase of rainfall, the location of landslides gradually develops from a stable state to an unstable state, and the number of landslides in the unstable zone gradually increases, indicating that rainfall has a significant impact on the slope stability of the study area. By comparing the simulation results with the actual rainfall-triggered landslide disasters. It can be concluded that the SINMAP model is effective in simulating and predicting the regional stability of shallow loess landslide induced by rainfall in the loess region, as well as can be used in the stability assessment of shallow landslide in the loess region.
