Large movable lateral uplifting composite lading slope physical model test apparatus

A large movable lateral uplifting composite lading slope physical model test apparatus comprises a test framework, a bottom uplifting mechanism, a rear portion loading mechanism and a water level elevating simulation mechanism; the bottom of the front portion of the test frame is hinged to the test site ground surface, the test frame is formed by mutually splicing a front panel at the front portion, at least two vertically-arranged guard boards and a frame baseboard at the bottom portion, and the spacing between adjacent guard boards is adjustable; the bottom uplifting mechanism is arranged below the test frame and is used for driving the rotation of the test frame around the hinge pint at the front portion; and the rear portion loading mechanism comprises a loading steel board, an electro-hydraulic servo loading machine and a counterforce wall, the counterforce wall is arranged behind the test frame, the rear end of the electro-hydraulic servo loading machine is hinged to the counterforce wall, the front end of the electro-hydraulic servo loading machine is connected with the loading steel board, and the rear portion loading mechanism is used for applying action force to a slope physical model in the test frame from the rear end of the test frame. The apparatus is suitable for large-size slope physical models, and can realize the establishment of three-dimensional models better satisfying geometric similarity conditions than real slopes.
