Abstract
The Shuping landslide was reactivated by the initial impoundment of the Three Gorges Dam Reservoir, China, in June 2003. For the purposes of landslide disaster mitigation in the reservoir area and identification of landslide movement and deformation caused by reservoir level changes, a monitoring system mainly consisting of drum-style extensometers was installed in the eastern part of the Shuping landslide. Systematical monitoring was started in August 2004 with installation of 13 extensometers above the waterline after the initial impoundment. In August 2006, 11 more drum-style extensometers were installed above the high waterline (175 m), and 5 flexible extensometers were installed along a longitudinal section in the elongation to low waterline. In August 2007, three more drum-style extensometers were installed to make the whole monitoring line connected. In this chapter, the monitoring results from August 2004 to May 2008 are presented, and the deforming of the Shuping landslide caused by both reservoir level changes and rainfall is examined.
