Water tank experiment device for simulating surface karst development

The invention provides a water tank experiment device for simulating surface karst development, and the device comprises: a water tank assembly which contains a gypsum model for simulating a three-dimensional ancient landform; aleaching assembly which is used for providing acid liquor leaching for the gypsum model in the water tank assembly; asolid-liquid separation assembly which is arranged below the water tank assembly and is used for carrying out solid-liquid separation on the leached reactants penetrating through the water tank assembly; and the acid liquor control assembly which is usedfor providing circulating acid liquor and adjusting the pH value of the acid liquor for leaching. According to the experiment device, the control effect of the ancient landform on the surface karst ofthe rock stratum can be simulated from a macroscopic perspective, the understanding of the development mechanism of surface karst cracks is deepened, the distribution rule of a marine carbonate rockhigh-quality reservoir is f
