Monitoring and deformation analysis of the Fujiayan landslide in Wanzhou,Chongqing

The Fujiayan landslide is a professional inspecting spot for the second early warning project of geological hazards inspecting in the Three Gorges Reservoir area. The inspecting method is surface displacement monitoring and deep displacement monitoring of the landslide body. Based on the contrast analysis of monitoring data over 3 years, it is found that there is some horizontal and vertical directions of deformation in each GPS deformation inspecting point, and the deformation in the monitoring point on the No. Ⅱ and No. Ⅲ sections is quite obvious. Each borehole have a obvious deformation, and the hole on the middle and underside cutaway section has a sharp deformation. At present the landslide is at a deformation stage of a uniform speed and at a unstable state.
