    Abstract
  • Karst collapse is a common geological disaster in karst area of China. Currently, the mechanisms of karst collapse development are mainly based on mechanical analysis. In this paper, the mechanisms of karst collapse development is studied based on the developing process of karst collapse. Two conclusions are obtained as follows,(1)According to the aquifer conditions, soils are divided into three types, the unsaturated soil in the aeration zone, the saturated soil in the unconfined aquifer and the pressurebearing soil in the confined aquifer;(2) On the basis of the interaction between groundwater and soils, three models of karst collapse are established as the disintegration model in the aeration zone, the seepage erosion model in the unconfined aquifer, and the hydraulic fissure model in the confine aquifer.
