Abstract

The invention relates to a multi-physical field coupling test device simulating slope instability. The device comprises a box body, an overload simulating system, a seepage simulating system, a raining simulating system, a slope inclination simulating system and a test system, wherein the top of the box body is provided with a slide way, the side of the box body is provided with a box body side plate, the overload simulating system comprises a slide block and a following loading device, the following loading device is connected to the slide block through a loading device hinge, the slide blockcooperates with the slide way and can slide on the slide way freely, and the following loading device further comprises a loading plate. Through adoption of the test device, a slope deformation instability mechanism under a condition of multi-physical field multiple physical effects of raining infiltration effect-soil unsaturation effect-underground water stable seepage effect-overload additionalstress effect-inclination stress field change effect can be discussed.

Description

Technical field: [0001] The invention relates to the technical field of geotechnical engineering, in particular to the research on slope stability analysis and prevention technology. Background technique [0002] As we all know, slope stability is crucial to the safety of railways, highways, dams and other projects. Once an accident occurs on a slope, it may cause huge economic losses. How to accurately evaluate slope stability is one of the major problems that many researchers need to solve. The slope stability is a very complex issue, which is affected by many factors such as geological factors, environmental conditions, and external forces. At present, the methods of theoretical analysis, numerical simulation, model test and field test are mainly used to study it. Among the above methods, model test is one of the important and effective methods to study this problem. However, the current model test method has a single consideration factor and is quite different from th...
