Abstract

The disaster of landslide seriously threatens the safety of people's life and property. Landslide deformation monitoring is the key to disaster prevention and reduction. We used Unmanned aerial vehicle (UAV) photogrammetry and interferometry synthetic aperture radar (InSAR), digital elevation of difference before and after the landslide, to analyze topographic changes, trace the evolution of deformation before the landslide, and monitor the deformation after the landslide. The result shows that The percentages of elevation lowering and elevation raising by volume are 55% and 45%. In addition, the evolution before landslide is a deformation accumulation process. The surface deformation after landslide show that landslide still deform. The cures of monitoring points distinct slow deformation stage and accelerated deformation stage.
