Abstract: Over the past decade, the studies have been growing rapidly on application of Synthetic Aperture Radar Interferometry (InSAR) technology to landslide deformation monitoring. On the basis of InSAR ground reflector, the paper has improved the design, produced a new InSAR reflector and successfully applied to Three Gorges Reservoir Shuping Landslide deformation monitoring.

Abstract: Our country is one of the countries that with serious geological disasters,every year we loss nearly twenty billion yuan and hundreds of people dead because of it.How to liberate deformation monitoring from the traditional way by means of modern Synthetic Aperture Radar Interferometry (InSAR) is the responsibility of each technical workers. In this paper, we mainly introduce the recent fast-developed advanced InSAR technology -- Persistent Scatterers for SAR Interfero try PS InSAR and its application on Shuping landslide in the Three Gorges reservoir area .

Abstract: Rainfall infiltration and reservoir water level fluctuation are major factors inducing slope deformation. Taking nearly three years data of Bazimen landslide in the Three Gorges Reservoir area and basing on the mathematical regression analysis method, a mathematical relationship among landslide deformation, water level and rainfall is established. And then the most adverse condition under the superposi¬tion of rainfall and reservoir water level is obtained.
