Description

technical field [0001] The invention relates to a slope test device, in particular to a model test device for slope mining under the action of surface and groundwater. Background technique [0002] With the vigorous development of geotechnical engineering in my country, the problem of slope has become a common problem faced by the engineering field. There are many types of slopes. According to the classification of origin, they can be divided into artificial slopes and natural slopes; according to the classification of stratum lithology, they can be divided into soil slopes and rock slopes; Slopes and temporary slopes. [0003] Among the influencing factors on the slope, the stability analysis of the slope under different load conditions is a very necessary research direction. In the model test of the slope, high ground stress is often encountered, and the simple soil weight simulation is difficult to achieve, and the There are not many groundwater simulations, and it is tro...

[0003] Among the influencing factors on the slope, the stability analysis of the slope under different load conditions is a very necessary research direction. In the model test of the slope, high ground stress is often encountered, and the simple soil weight simulation is difficult to achieve, and the There are not many groundwater simulations, and it is troublesome to discharge the water body after the experiment, which affects the efficiency of the experiment; the experiment of mining-induced slope instability is even rarer, and it is impossible to make a reasonable analysis and explanation of the slope failure under the comprehensive action. Efficiency, accuracy and practicality
