Abstract：Conventional methods of monitoring change in rock and soil are difficult to be used to implement continuous monitoring of ground deformation in large-size reservoir and its surrounding areas. In order to solve the key problem of monitoring the real-time change in rock and soil in the reservoir area of large scale hydropower station, the reservoir area of Wudongde hydropower station was selected as the study area. According to change types of rock and soil, D-InSAR technique and false color composite technology were used to monitor changes respectively, and changing region was extracted finally. Comparing the results derived from two methods with that of field investigation, the deformation locations of rock and soil as well as its trends are in agreement. It meets the monitoring purpose including discovering change and monitoring trend. It is proved that the combined method of D-InSAR technology and false color composite technology is feasible to monitor the wide-area change in rock and soil.
