Abstract

The Lotus Pond landslide developed in a large-scale cataclinal slope on the right bank of Yangtze River. It has been reactivated by impounding of the Three Gorges Reservoir. Based on geological survey and experimental tests, deformation characteristics and failure mechanism have been ascertained. The Lotus Pond landslide is a successive landslide formed by three periods of sliding at different elevations; the three slides have similar shapes in the longitudinal profile. The toes of the later slides thrust and overlie the heads of the early slides on circular rupture surfaces. However, the successive slides exhibit different failure mechanisms, namely, buckling, planar slide, and “toe-break” mechanisms.
