In-situ loading test device for slope

An in-situ loading test device for a slope comprises a support substrate 1 and casters 2, a support frame 3 on the support substrate, a test stand 4 for testing provided on the support frame, a loading assembly 5 for loading a slope body to inside of the test stand on one side of the top surface of the support substrate 1, a water body simulation assembly 6 at the top of the support frame and located directly above the test stand 4 which has a sloping surface on the inside, a shield 7 vertically slidingly mounted at bottom end of the sloping surface, and a regulating device 8 for controlling lifting and lowering of the shield. Erosion of the slope is tested using the water body simulation assembly dripping water down the slope surface.
