Experimental device for simulating sliding of rock block

Abstract

The invention relates to an experimental device for simulating rock block sliding, and belongs to the technical field of geological disaster prevention and control. Comprising a variable-angle rock block sliding platform, a sliding panel and a storage adjusting device. The sliding-off panel is arranged on the rock block sliding-off platform with the variable angle; the variable-angle rock block sliding platform comprises a first panel, a second panel and a first angle adjusting device, wherein the first panel and the second panel are oppositely arranged, and the first angle adjusting device is arranged between the first panel and the second panel. The storage adjusting device comprises lateral baffles arranged on the two sides of the rock, a shaft arranged in the lateral baffles, a ball bearing arranged on the shaft and cushion covers arranged at the two ends of the ball bearing. According to the invention, the occurrence, surface morphology, opening degree and filling degree of the structural surface in the rock block can be fully simulated, and the motion state of the rock block sliding along the plane and the motion state of the wedge-shaped body sliding along the double surfaces under the action of multiple parameters of the structural surface can be discriminated.

Description

technical field [0001] The invention belongs to the technical field of geological disaster prevention and control, and relates to an experimental device for simulating the sliding of rock blocks. Background technique [0002] Rocks have undergone a long period of geological tectonic action, and within them there are discontinuous surfaces of various scales, also known as structural surfaces. The structural plane plays a crucial role in the evaluation of rock mass stability. The mechanical properties of the structural plane are obviously weaker than that of the complete rock mass, which greatly threatens the stability of the engineering rock mass. It can form a dangerous rock mass with different combinations and different instability modes with the slope surface of the slope, which will pose a threat to the construction of roads, bridges, houses and other projects and the safety of people's lives and properties. [0003] The influencing factors of rock mass stability on stru...

Problems solved by technology

[0003] Factors affecting the stability of structural planes include multi-parameter information such as occurrence, surface morphology, opening, and filling conditions. At present, experimental research on the sliding of rock blocks mostly focuses on simulating the occurrence of structural planes, lacking in simulating the surface morphology of structural planes. Experimental research on the sliding of rock blocks under the joint action of multi-parameters such as , opening and filling conditions, the mechanism of the influence of multi-parameter information on these structural planes on rock block sliding has not been fully explored
