After the second water pump 510 is started, the water source in the storage water tank 310 enters the inside of the water storage box 540 through the second water inlet pipe 520 and the water outlet hose 530, and finally flows out from the water outlet holes 543 at the bottom of the water storage box 540 to the surface of the landslide body simulation piece 210, so that the landslide body simulation piece 210 can be quickly soaked to a saturated state. When the landslide body simulation piece 210 is soaked to a saturated state, the second hydraulic cylinder 550 is started to drive the water storage box 540 to rotate above the bedrock simulation piece 20, so that the water storage box 540 moves away from the landslide body simulation piece 210.

[0065] The water outlet main pipe 570, the water outlet branch pipe 580 and the partition 590 are arranged so that the water source discharged from the water outlet hose 530 is separated in the water storage box 540. That is, the partitions 590 divide the water storage box 540 into water storage cavities of different heights. The third valves 571 on the outer part of the water outlet main pipe 570 are opened one by one from low to high. Each water storage cavity corresponds to water storage, and the water source in the water storage cavity can be discharged from the water outlet hole 543 to the landslide simulation piece 210 in the corresponding area, so that the landslide simulation piece 210 is quickly immersed from low to high to a saturated state. That is, the landslide simulation piece 210 is quickly wetted to a saturated state at multiple height positions, which enriches the test variables and increases the data obtained by the test when the landslide simulation piece 210 is immersed to saturation at multiple water level heights, thereby enriching the test.

[0066] It should be noted that the specific model and specification of the second water pump 510 and the second hydraulic cylinder 550 need to be determined according to the actual specification of the device. The specific selection calculation method adopts the existing technology in the art, and therefore will not be described in detail. The power supply and principle of the second water pump 510 and the second hydraulic cylinder 550 are clear to those skilled in the art, and will not be described in detail here.

[0067] In some embodiments of the present application, the bottom end and the top end of the water storage box 540 are respectively provided with sealing strips. The sealing strips can be sealed by rubber strips to reduce water leakage from the gaps and improve the efficiency of water infiltration into the landslide simulation piece 210.

[0068] The landslide accumulation body seepage hysteresis simulation test device described above can only simulate the water level rise and fall in a static water flow state, and is mainly suitable for reservoirs, lakes and other areas where water flow is not easy to flow. It cannot be used for water flow dynamic test to enrich the test items of the device.

[0069] Please refer to Figure 8The landslide accumulation body seepage hysteresis simulation test device further comprises a water flow simulation mechanism 60, which comprises a circulating pump 610, a water outlet tank shell 620, a water return tank shell 630, a longitudinal water outlet pipe 640, a longitudinal water return pipe 650, a transverse water outlet pipe 660, a transverse water return pipe 670, a flow guide pipe 680 and a backflow pipe 690. The box body 110 is provided with a mounting groove on both sides, and the water outlet tank shell 620 and the water return tank shell 630 are respectively fixedly embedded in the mounting grooves. The outer walls of the water outlet tank shell 620 and the water return tank shell 630 can be provided with sealing gaskets to improve the sealing effect. The opposite sides of the water outlet tank shell 620 and the water return tank shell 630 are respectively provided with openings, and the openings of the water outlet tank shell 620 and the water return tank shell 630 are respectively provided with filter screen plates 631 to prevent large particles of silt from entering the circulating pump 610. The longitudinal water outlet pipe 640 is arranged on the side of the water outlet tank shell 620 away from the box body 110, a plurality of groups of transverse water outlet pipes 660 are respectively connected to the box body 110 and the longitudinal water outlet pipe 640, the transverse water outlet pipes 660 are provided with fourth valves 661 outside, the flow guide pipe 680 is respectively connected to the water outlet port of the circulating pump 610 and the longitudinal water outlet pipe 640 at both ends, the longitudinal water return pipe 650 is arranged on the side of the water return tank shell 630 away from the box body 110, a plurality of groups of transverse water return pipes 670 are respectively connected to the box body 110 and the longitudinal water return pipe 650 at both ends, the transverse water return pipes 670 are provided with fifth valves 671 outside, and the backflow pipe 690 is respectively connected to the water inlet port of the circulating pump 610 and the longitudinal water return pipe 650 at both ends.

[0070] It should be noted that the circulating pump 610 is an adjustable pressure type water pump. The specific model and specifications of the circulating pump 610 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the art, and therefore will not be described in detail. The power supply and principle of the circulating pump 610 are clear to those skilled in the art, and will not be described in detail here.

[0071] When the circulating pump 610 is started, the water source in the box body 110 flows from the water return tank shell 630 to the circulating pump 610 through the transverse water return pipes 670, the longitudinal water return pipe 650 and the backflow pipe 690; and then the water source flows into the water outlet tank shell 620 through the flow guide pipe 680, the longitudinal water outlet pipe 640 and the transverse water outlet pipe 660, and flows out to the inside of the box body 110. The water return tank shell 630 and the water outlet tank shell 620 cause the water source in the box body 110 to flow, which is used to simulate the flow of the water source in the river. By adjusting the pressure of the circulating pump 610, the influence of different flow rates on the landslide body simulation piece 210 can be adjusted.

[0072] In order to simulate the influence of the water flow in the box 110 and the water flow at different heights on the landslide simulation piece 210, the fifth valve 671 outside the lateral backwater pipe 670 and the fourth valve 661 outside the lateral water outlet pipe 660 are opened to simulate the influence of the water flow at different heights on the landslide simulation piece 210. The water flow simulation can also be combined with the water level rising or falling test to obtain more test data of the influence of the water flow and the water level change on the landslide simulation piece 210.
