ABSTRACT
In this paper, the application of the time-series InSAR analysis method in landslide deformation trend prediction is discussed by taking the landslide approach road of a substation in Danba as the experimental area. By comparing the cumulative displacement monitoring map of landslides, the large deformation area is obtained, and it is taken as the key research object for zoning monitoring. According to the comprehensive field investigation and time series InSAR monitoring, there were no obvious macro deformation signs in the trailing edge I area and the downstream side II area. At the same time, there were obvious macro deformation signs and more complex deformation phenomena in the upstream side approach road section III area. There were many deformations in the micro monitoring. In March 2017, both the deformation amount and deformation rate increased. Progressive deformation occurred in the slope, and the deformation tended to intensify. The maximum cumulative deformation in this area exceeded 150mm. Then the landslide is in slow creep.
