Analysis of development characteristics and inducing conditions of collapses in the distribution area of clastic rocks in Guizhou
Landslide is the main geological hazard in the distribution area of clastic rocks,and collapse is often ig-nored.The analysis of the inducing conditions of clastic rock collapses can guide the prevention and control of col-lapses in the distribution area of clastic rocks.Taking Yungui Mountain Collapse as an example,this paper uses ground survey,remote sensing,numerical simulation and other technical means to analyze its geological disaster characteristics,movement characteristics and inducing conditions.The induction analysis method is used to summa-rize the inducing conditions of clastic rock collapses.The results show that the Yungui Mountain Collapse is a small collapse,the failure mode is mostly tipping,and the influence range is within 112 m.Steep terrain,combination of hard rock and weak interlayers,near-horizontal slope structure and differential weathering are the main inducing conditions of Yungui Mountain Collapse.Geomorphology,special lithology combination and exposure of the contact surface between hard and soft rocks have great influence on the formation of clastic rock collapses.
