Taking Muli county, Liangshan prefecture, Sichuan province as an example, based on the Sentinel-1A ascending and descending orbit SAR data provided by the European Space Agency, the visibility of SAR satellite surface monitoring and the sensitivity of slope deformation monitoring in different slope directions were quantitatively analyzed, and typical landslides in the region were selected to carry out fine monitoring and volume inversion research. Combined with the slope constraints, the three-dimensional deformation field of the lattice landslide in the area was inverted by using the LOS deformation results of the lifting rail. The results show that the landslide mainly moves horizontally and slides down the slope, with the maximum horizontal displacement rate exceeding 100 mm/a. The maximum annual deformation rate in the vertical and northward direction is between 40 and 60 mm/a, and the north-south and vertical deformation characteristics of the landslide are related to the local topography of the landslide surface.Based on the vector tilt method and the mass conservation method, the depth and volume of the landslide are inverted.The results show that the area with the greatest depth of the landslide is located in the middle of the slope, with a maximum depth of 52 meters, the volume of the landslide is between 2.2×107 m3 and 2.8×107 m3. And the results of the two methods have high consistency. This study provides a technical reference for the monitoring, disaster prevention and mitigation of typical landslides in southwest China, and the estimation of the impact range of landslides.
