Description

technical field [0001] The invention relates to the field of rock and soil engineering, in particular to a model test device for simulating rock and soil slope instability and damage. Background technique [0002] Slope stability refers to the degree of stability of slope rock and soil under certain slope height and slope angle conditions. Under the action of load, wind, earthquake, rainfall and other inducing factors, natural or artificial slopes may slide or collapse, causing natural disasters. Large-scale slope damage can cause traffic interruption, building collapse, river blockage, reservoir silting, and bring huge losses to people's lives and property. The purpose of studying slope stability is to predict the time, scale, and degree of damage of slope instability, so that preventive measures can be taken in advance to reduce geological disasters. [0003] There are many factors affecting slope stability. The existing test equipment for simulating rock and soil slope ...
