Maoping Landslide is a large ancient rock landslide in the region of Geheyan Reservoir of Qingjiang River. Since the filling of the reservoir in April 1993, the deformation of the landslide has become obvious day after day. Base on the deformation measurement data from field investigations and lab tests in 12 years, this paper probes into the deformation characteristics of the landslide and its induced mechanism and analyzes the landslide stability under various engineering conditions by using 3D finite element numerical simulation as well. The stability numerical calculation results show that the landslide is in a latency critical state. It...
