Analysis on the landslide regulating design of the Kwan-yin psavilion in Three Gorges reservoir

The landslide of the Kwan-yin Pavilion in Three Gorges is known in China. It is a typical succession tectonics landslide. It is also a large composite soil landslide, about 43 kilometers to Three Gorges Dam. As early as 1933, the landslide happened large-scale slippage. Slump deposit rushed down into Yangtze River and shaped the disorderly hillock landform. In these years, this landslide relives because of the sluice of Three Gorges Reservoir. Sheared fracture appears in the front edge and tensile cracks are obvious in the after-edge. It comes into creep deformation phase. When the water level reaches 156 meters to 175 meters, or disaster rainstorm happens, the landslide maybe slip largely. That will threaten the safety of roads and countries, and dwellers' life and property. If the landslide body rushes down into Changjiang River, the river route will be jammed. Disaster loss will happen for the round ships. The author takes part in the geology disaster reconnaissance and regulating design of the landside. The paper analyses the design scheme of the Kwan-yin Pavilion landslide and provides the design way for the future research on the succession tectonics landslide.
