Abstract: An integrated test device and method for filling karst cave deposition and tunnel intermittent water and mud inrush disasters. The device includes a mixing tank, water tank, water collection tank and plurality of depositing tanks, wherein mixing tank outlet is connected to one end of a pipe, the other end of the pipe extends to one end of the water tank, the plurality of depositing tanks are arranged underwater tank at intervals, the water collection tank is arranged at the water tank's other end, and a detachable baffle is arranged in the water tank and in front of each depositing tank. The deposition and consolidation of filling media and water and mud inrush can be simulated and observed through the setting and cooperation of the plurality of depositing tanks, different working conditions can be simulated by changing the flow rate, sample concentration, particle gradation, depositing height and displacement.
