The invention relates to a model test device for measuring the stability safety coefficient of a rock slope, and the device comprises a rock slope model and a mounting seat, the mounting seat is provided with a rotating assembly, the rotating assembly is provided with a placement part, the rotating assembly drives the placement part to rotate, the placement part is provided with a detection assembly, and the detection assembly is electrically connected with the rotating assembly. One side of the placing piece is fixedly connected with a rotating rod, a fixed rod is mounted on the mounting seat, a connecting shaft is mounted on the mounting seat, the connecting shaft is inserted in the fixed rod and the rotating rod in a penetrating manner, and an angle measuring assembly is mounted on the connecting shaft. The position of the detection assembly is adjusted so as to detect the rock slope model, the rotating assembly drives the placement piece and the rotating rod to rotate, the rotating rod drives the connecting shaft to rotate, when the rock slope model is unstable, the detection assembly sends a signal, the rotating assembly is closed, an operator reads a numerical value on the angle measurement assembly, and the stability of the rock slope model is ensured. Therefore, the stability safety coefficient of the rock slope is calculated, and the accuracy of measuring the stability safety coefficient of the rock slope is improved.
Description
technical field [0001] The application relates to the technical field of slope safety factor measuring equipment, in particular to a model test device for measuring rock slope stability safety factor. Background technique [0002] The rock slope is the air surface with a certain inclination formed by the rock mass under the action of natural gravity or human action. Due to the instability of the rock slope, not only the slope body itself is destroyed by the structure, threatening the existing buildings around, forming a major safety hazard, but also, due to the instability of the rock slope, the rock avalanches and collapses are caused. The lower buildings and the safety of human life and property cause immeasurable losses, so the stability of rock slopes has always been one of the important research contents of geotechnical engineering. [0003] The slope stability safety factor refers to the ratio of the anti-sliding force to the sliding force along the assumed sliding su...
