Cover collapse sinkhole is one of the hot topics for scholars. Deep valleys are distributed in Southwest of China Karst Mountains. The well-off rainfall, fast recharge and discharge cycle of groundwater leading to a high degree growth of karst. Fracture type and pipe type-karst pipes are common in these regions, so the hydrodynamic is complex and changeable. cover collapse sinkhole has great influence on the highway or other traffic hub, such as route selection, city construction, it threatens construction safety and people lives. In prone or high incidence areas of cover collapse sinkhole, the geological structure of the cover-layer is changeable, and the pressure of water and air is always abrupt. The deformation and evolution process of the cover is complicated under the water and air interaction.

In the study, it is the first time that Cellular Automata was adopted to simulate cover collapse sinkhole, there may be set a precedent to cover collapse sinkhole study. The object oriented method was used to construct the cellular space, and the CA-Collapse model was established, and the cover collapse sinkhole under certain hydrodynamic conditions was preliminarily discussed, which provided a new idea for the study to simulate and predict cover collapse sinkhole.
