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.
