The power supply of the circulation pump 610 and its principle will be clear to a person skilled in the art and will not be described in detail here.

When the circulation pump 610 is started, the water source in the tank 110 enters the circulation pump 610 from the return water tank shell 630 through the transverse return pipe 670, the longitudinal return pipe 650 and the return pipe 690; the water source enters the water outlet tank shell 620 through the guide pipe 680, the longitudinal water outlet pipe 640 and the transverse water outlet pipe 660 and flows out to the inside of the tank body 110. The water return tank shell 630 and the water outlet tank shell 620 both cause the water source flow inside the tank body 110 to simulate the water source flow in a river, and the influence of different flow rates on the landslide body simulation member 210 can be simulated by adjusting the pressure of the circulation pump 610.

In order to create the influence of the water flow in the box 110 and the water flow with different heights on the landslide body simulator 210, the influence of the water flow with different heights on the landslide body simulator 210 can be simulated by opening the fifth valve 671 outside the designated transverse water return pipe 670 and the fourth valve 661 outside the transverse water outlet pipe 660. And the water flow simulation can be matched with the water level to rise or fall for testing, so that the influence of water flow and water level change on the landslide body simulation part 210 under more conditions is obtained, and richer test data are obtained.
