Background

Karst collapse (karst collapse) is a karst cave, an overlying sediment and underground water, and forms a solid, liquid and gas three-phase mechanical balance system, the underground water level changes to a certain extent, the balance is destroyed, the overlying loose sediment suddenly collapses to form a conical collapse pit with a large upper part and a small lower part. Karst ground collapse is the main type of ground deformation damage and mostly occurs in soluble rock distribution areas such as carbonate rock, calcareous clastic rock and salt rock. Groundwater movement is the dynamic condition generated by collapse, the zone of sharp change of groundwater level is the sensitive area generated by collapse, and the change of the hydrodynamic condition is the main trigger factor for generating collapse. The reasons for the rapid change of hydrodynamic conditions mainly include rainfall, reservoir storage, underground water filling, irrigation leakage, severe drought, mine drainage, strong water pumping and the like. In addition, the karst ground collapse can be induced by earthquake, additional load, strong corrosion of acid-base waste liquid discharged artificially to the soluble rock and the like.
