RAPID AND LONG-TRAVEL MECHANISM OF QIANJIANGPING LANDSLIDE AND DEFORMATION MODEL OF SHUPING LANDSLIDE IN THREE GORGES RESERVOIR AREA, CHINA

After the first impoundment of the Three Gorges Reservoir, the Qianjiangping landslide, which is located in Qingganhe River, a tributary of Yangtze River, slid rapidly and travelled for long distance. Through ring shear tests on the samples taken from the sliding zone of the landslide, the mechanism was clarified. The Shuping landslide shows active deformation after the first impoundment. Its deformation model was analyzed based on the monitoring data for more than three years.
