Karst Collapse Characteristics and Evolution Mechanism of the Sunzu River Rubber Dam
To avoid threat of karst collapse to implementation of the Sunzu River rubber dam project,characteristics of karst collapse in the research area were systematically analyzed by means of field survey,engineering geological mapping,drilling,field test,and stability analysis,so as to explore genetic evolution mechanism of karst collapse and identify inducing factors of karst collapse.Stability and evolution trend of karst collapse in the research area were predicted.The results show that the research area is in the stage of soil cave formation at present,and the change of external hydrody-namic conditions is the main influencing factor of the stability of karst collapse in the research area.There are space,material,and hydrodynamic conditions for further development of karst ground collapses,and the maximum groundwater level depth should be controlled during groundwater exploitation.
