| description | The invention discloses a physical simulation test device for researching karst collapse causes. The physical simulation test device comprises a main body model, a water injection and drainage system and a multi-data monitoring and acquisition system, according to the device, in the test process, the fluctuation state of the underground water level is controlled through water injection and drainage measures and can be accurately adjusted to the underground water level required by the test, so that various types of karst collapse caused by karst pipelines or karst cracks at the bottom are simulated; comprising various complex working conditions such as water level descending-permeation subsurface erosion-karst collapse, water level sudden descending-negative pressure suction erosion-karst collapse, water level sudden rising-positive pressure impact explosion-karst collapse and water level repeated rising and falling-positive pressure/negative pressure circulation action-karst collapse, and can be visually refl |
