[0032] Example one
[0033] A three-dimensional model test device for simulating water and mud inrush geological disasters, including a lower support frame, a confining pressure loading device, an axial pressure loading device, and model sample parts. The confining pressure loading device is set on the top of the lower support frame and the model sample parts are set In the confining pressure loading device, the axial pressure loading device is arranged in the lower support frame, and the axial pressure loading device passes through the bottom of the confining pressure loading device and is connected to the model sample part.
[0034] The lower support frame includes a base 1 and four uprights 3, and the four uprights 3 are uniformly welded on the base 1.
[0035] The axial pressure loading device includes an oil cylinder 2, a force sensor 4, a displacement sensor 5 and a piston rod 6. The bottom of the oil cylinder 2 is fixed on the base 1 by bolts. The bottom end of the piston rod ...
