Analysis of Typical Example and Genesis of Landslide Triggered by Wenchuan Earthquake in China
As the main geohazard triggered by Wenchuan earthquake,landslide is widely distributed.It caused many people lost their lives and incipient fault.This paper analyzes the genesis of these landslides from the aspects of geomorphy,geological structure of slope body,rock characters,earthquake motion,stable condition of slope,weathering effect and stream action.Strong earthquake motion near the fracture zone and geological structure of slope body are the main reasons caused the slope failure.Take Wangjiayan landslide as the typical example,the genesis of earthquake-induced landslide is analyzed.Strong earthquake motion near the fracture zone and the extroversion structural surfaces are the main reasons caused the slide,and great slope and instable state of slope can also promote the slop failure.Failure process of slope is also analyzed.
