Study on Inducement and Treatment of Karst Collapse in a Region of Zaozhuang
In order to further explore the occurrence,developmental characteristics and causes of karst disaster collapse and improve the effectiveness of geological disaster control,a region in Zaozhuang was taken as an investigation and research area to analyze the distribution law and characteristics of karst collapse,and to further explore the mechanism of inducing collapse in this region.It is determined that karst fissure is the basic condition of collapse disaster,lithologic structure of overburden is the main factor of collapse,and over-exploitation of groundwater is the direct cause of collapse.Three kinds of formation mechanisms of karst collapse phenomena are determined,which are mainly infiltration erosion,vacuum absorption erosion and loss of weight loading effect.According to the actual situation of karst collapse in this region,it is proposed that the disaster control should be carried out by monitoring and preventing ground cracks of the collapse body and the hidden hidden points of karst collapse in the area,reducing the exploitation of karst water by reducing the exploitation of urban water plant,and shutting down small and medium-sized polluting enterprises in the area,so as to provide certain references for effectively control-ling karst collapse disasters.
