Abstrakt: The paper represents the models of subsidence sinkhole in soils around reservoirs in karst region. There are three essential conditions of the formation, such as cavity-fissure, overlying soils and groundwater dynamic. It leads to subsidence sinkhole based on three conditions when reservoirs change the underground hydrodynamics with regulating water. With the change of the surface water level controlled by reservoirs, the groundwater level alters, meaning to break the initial balance of sinkhole formation mechanism. Five models are established to describe the general mechanism change of groundwater hydrodynamic in this paper.
