Abstract

The invention provides a slope instability dynamic evolution device capable of simulating various slip factors indoors, and the device comprises a model framework unit, an overlying load loading unit, an impact unit and an underground water and rainfall simulation unit, and can apply single impact vibration to a sample to simulate blasting vibration. The slope instability dynamic evolution device capable of simulating various slip factors indoors can be used for carrying out a large-scale slope engineering indoor similarity simulation test, so that the dynamic evolution process of slope instability is tracked, analyzed and researched, the dynamic spatio-temporal evolution law and expression form of slope landslide damage from formation, stabilization, inoculation, development and damage are obtained, and according to the understanding of the law and characteristics of slope instability damage, the method which can be used for early warning of temporary sliding before slope instability is studied, so that technical support is provided for timely and accurate early warning before slope instability damage.

Description

technical field [0001] The invention relates to the technical field of engineering tests, in particular to an indoor slope instability dynamic evolution device capable of simulating various sliding factors. Background technique [0002] Landslide is a geological phenomenon of slope rock and soil sliding along the normal shear failure surface. With the continuous growth of the world's population, the space for human production and living continues to expand, and engineering activities supported by economic and technical conditions are increasingly Frequent landslides, coupled with the influence of global climate change factors, frequent landslide disasters, many of which are large-scale landslide disasters, causing huge casualties and property losses. So far, landslide disasters have occurred in all areas with human production and living activities . [0003] Mine slope stability is a major problem that my country's open-pit mines, especially deep mining open-pit mines, must...
