The problem that underground rock-soil testing cannot be performed on mountains at different angles is solved, a push block can be driven to move through an arranged telescopic rod, the inclination angle of a simulation plate can be changed through the push block, rainfall is simulated through a spray head, underground rock-soil testing of the mountains at different angles is performed, the influence of rainfall on underground rock soil at different angles is avoided, so that the test result is more accurate.

Description

technical field [0001] The invention relates to the field of engineering test devices, in particular to a geotechnical engineering simulation test platform for studying potential failure surfaces. Background technique [0002] The underground geotechnical engineering research of mountain road construction focuses on the stability evaluation of rock and soil mass and the reinforcement effect. In the process of theoretical analysis calculation and numerical simulation test of geotechnical engineering stability evaluation, the mathematical calculation method must adopt abstract Many rock and soil mechanics parameters use the average value and mechanical conversion. As a result, the engineering environment of the research object is too simple and ideal, which is far from reality. The engineering field turns to engineering tests to seek stability evaluation and prediction results. There is engineering waste and the result cannot be verified by repeating the test.

Problems solved by technology

[0004] Based on this, the purpose of the present invention is to provide a kind of geotechnical engineering simulation test platform that research has potential damage surface, to solve the problem that the existing geotechnical engineering simulation test platform usually only studies the mountain body at the same angle, but the The inclination angles of various parts are different, so the test data during the research is relatively single, and the research cannot be carried out based on the underground rock and soil on the mountain with different inclination angles, which may lead to the problem of short service life of the road during road construction, and in When testing, the impact of rainwater on underground rock and soil is usually simulated and only used once, which is a wasteful technical problem

[0006] By adopting the above technical solution, the problem of not being able to conduct underground geotechnical tests on mountains with different angles is solved. The telescopic rod can drive the push block to move, and the push block can change the inclination angle of the simulation board, and simulate rainfall through the nozzle. In order to test the underground rock and soil of different angles of the mountain, the influence of rainfall on the underground rock and soil at different angles can make the test results more accurate and achieve the purpose of reusing the used water. The solenoid valve can be set to achieve It is convenient to control the size of the water outlet from the nozzle and realize the problem of simulating the amount of rainfall. The filter plate can filter the soil that rainwater washes and falls. The soil falls into the collection box, and the mud water is blocked by the push plate. After precipitation The soil is located on one side of the push plate, and the water pump can reuse the settled water to achieve the purpose of saving resources, and the push plate can also clean up the settled soil and push the soil out of the collection box, so that the internal water can be used higher rate
