Abstract

The invention discloses a magnetic field force-seepage force model test device applicable to an earth-rock slope. The magnetic field force-seepage force model test device mainly comprises a talus body, a magnetic force layer, an infiltration tank, a header tank, a deformable permeable leg protecting body, a rainfall pipe, a displacement sensor and a pore pressure gauge, wherein the talus body and the ground form an angle of 20-45 degrees; the magnetic force layer is arranged below the talus body and parallel to the talus body; the infiltration tank is arranged at the upper end of the talus body, communicated with a water source and used for exerting seepage force along the slope on the talus body; the header tank is arranged in the direction of the lower end of the talus body and used for collecting seepage; the deformable permeable leg protecting body is arranged between the lower end of the talus body and the header tank and used for maintaining slope legs of the talus body; the rainfall pipe is arranged above the talus body, communicated with the water source and used for simulating rainfall; the displacement sensor is arranged above the talus body; the pore pressure gauge is arranged inside the talus body. The magnetic field force-seepage force model test device can really simulate effective stress and water pressure of the earth-rock slope inside the slope body under the synergistic effects of the seepage force along the slope and the magnetic field force of the vertical slope, the problem that a geotechnical model experiment cannot easily meet the geometric similarity and the physical similarity is solved, and a research means is provided for ecological protection of the earth-rock slope.

Description

technical field [0001] The invention relates to the technical field of earth-rock slope ecological protection, in particular to a model test device suitable for earth-rock slope ecological protection. Background technique [0002] In terms of geotechnical model tests, the current popular tests mainly include conventional model, magnetic geological model and centrifugal model test. Different from rock and concrete, for soil, the correct simulation of effective self-weight stress and water pressure is the key to the success of its geotechnical model test. The results of a large number of indoor tests on soil and rock materials show that the soil and rock materials have the following characteristics: [0003] ① The stress-strain relationship is elastic-plastic and nonlinear; [0004] ②The stress-strain relationship behaves differently under different stress levels. The deformation modulus and strength of the soil are closely related to the stress level, and this correlation i...
