Study on the Mechanism Forming Karst Ground Collapse Disaster in a Region of Guangxi

LIAO Jian-lin;The Fourth Geological Team of Guangxi Zhuang Autonomous Region;  
In this paper, the Karst ground collapse disaster in a certain area of Guangxi was taken as an object. Based on the internal and external factors affecting the Karst ground collapse in the study area, the formation process and mechanism of Karst ground collapse were analyzed. The collapse model and collapse mechanics model of Karst ground collapse were put forward. The results showed that rainstorm and groundwater level fluctuation induced into Karst ground collapse and the Karst collapse models were divided into the submerged erosion-erosion-gravity collapse model and the softening-loss-loading-vacuum erosion collapse model. The results can provide a guidance for the prediction and prevention of Karst ground collapse and groundwater exploitation in this area.
