ABSTRACT
This chapter discusses the deforming mechanism of the Shuping landslide, based on the deformation monitoring by extensometers, which was started in 2004. Shuping landslide is a reactivated landslide triggered by the first impoundment of the Three Gorges Dam Reservoir, China in June 2003. For the purposes of landslide disaster mitigation in the reservoir area and clarification of the mechanism of landslide movement caused by water level changes of dam reservoir, a monitoring system mainly consisting of drum style extensometers was installed in Block-1 of the Shuping landslide. The ongoing construction of the Three Gorges project in China from December 2004 is the largest hydropower project in the world. The dam site is located at Sandouping town, Zigui County, Hubei Province. When the dam was partially completed, it started to impound water in the reservoir to produce power and control the water to prevent flooding in the downstream area.
