Problems solved by technology

One of the methods is to simulate the slope instability process by loading the jack step by step to promote the failure of the model sample, but this method ignores the degradation effect of water on the rock and cannot completely reproduce the mechanism of this type of slope instability The other is to simulate the real rainfall scene by means of artificial rainfall. This scheme can well reflect the damage mechanism of rainfall to the slope. However, due to the extremely slow process of water-rock interaction, the experimental cycle of this scheme and long

Description

technical field [0001] The invention relates to the technical field of rock and soil mechanics, in particular to a model test device and method for the research on water-induced deterioration of rock slopes. Background technique [0002] Among all kinds of natural disasters, landslides belong to the huge geological disasters, and rainfall is the main inducement to trigger geological disasters such as landslides and debris flows. In my country, the losses caused by landslides caused by rainfall are huge every year. In this regard, the study of slope stability has become a very important topic. Among them, it is very necessary to conduct model test analysis of water-induced degradation for slopes with different rock and soil types and slopes, which can provide indispensable and important data for improving slope stability. The commonly used research methods include theoretical analysis, actual observation, numerical simulation and physical model test. Among them, physical mo...
