Cause and Stability Analysis of Daomakan Lanslide in Xiangjiaba Reservoir
Daomakan slope, a typical ancient slope by Jingsha River, locates in Xiangjiaba Reservoir. With the rising of water level of Xiangjiaba Reservoir, Daomakan slope might pose threaten to the reservoir. Based on the detailed field investigation, the author firstly proves that Daomakan slope is an ancient landslide by the following evidences: a 1.5 meters cracked layer was found at the front of the landslide and a very deep shearing scratch appeared on the bedrock surface. Meanwhile, the evidences above can be used to speculate that the strong earthquake is the main cause in triggering the landslide. According to the triggering and sliding process, stability analysis is conducted from an engineering geological perspective. The method adopted in this paper is suitable for field investigation, and provides a certain reference value on the ancient seismic landslides stability analysis in Xiangjiaba Reservoir area.
