Embodiment 1
[0029] The magnetic field force-penetration force model test device applicable to earth-rock slopes in this embodiment has a structure as attached figure 1 , 2As shown in and 3, the composition includes a chamber and a slope body 10 located in the chamber at a slope angle of about 20° to the ground, a magnetic layer 7 located directly below the slope body and parallel to the slope body, and located at the upper end of the slope body and adjacent to the slope body. The water source is connected to the seepage tank pool 14 for applying a slope-wise seepage force to the slope accumulation body, the sump pool 5 located at the lower end of the slope accumulation body for collecting seepage water, and the sump pool 5 located between the lower end of the slope accumulation body and the sump sump pool for maintaining the slope. The toe-protecting body 4 of the slope toe of the slope, the rainwater pipe 18 for simulating rainfall connected to the water source above the slope, the displ...
Embodiment 2
[0031] The magnetic field force-permeability model test device applicable to earth-rock slopes of this embodiment is basically the same as the structure of the test device described in Example 1 on the whole, the difference is that the test device is an open structure, and the slope accumulation body 10 The frame and the ground are set at a slope angle of 45°, and the ferrous aggregate in the slope accretion body is iron filings with a particle size distribution range of 0.25-2.0 mm, accounting for about 30% by weight; the magnetic layer 7 is a permanent magnet material plate , placed directly under the slope accumulation body, and integrated with the slope accumulation body; the water source connected to the seepage tank is an adjustable pressure water pump.
Embodiment 3
[0033] The magnetic field force-permeability model test device applicable to earth-rock slopes of this embodiment is basically the same as the structure of the test device described in embodiment 1 on the whole, the difference is that the slope deposit body 10 is connected to the ground by building the support body. Set at a slope angle of 30°, the ferrous aggregate in the slope accumulation body is iron filings with a particle size distribution range of 0.25-2.0mm, accounting for about 15% by weight; the magnetic layer 7 is a permanent magnet material plate, suspended on the slope Below the body; the water source connected to the seepage tank is a water tank whose height can be adjusted.
