Description

technical field [0001] The invention relates to an experimental device for indoor simulating on-site slope engineering, which is mainly used for indoor dam model experimental research on bulk slope engineering such as mine dumps and tailings dams, and belongs to mine slope engineering in geotechnical engineering . Background technique [0002] Bulk slopes such as dumps and tailings dams are important facilities for mining enterprises and an important link to ensure the normal production of mining enterprises. Now, with the construction of various factories and mines and the increasing scale of production, the amount of waste rocks and tailings discharged from mines has also increased sharply, which has led to increasingly prominent safety and environmental protection issues for many tailings dams and dumps. Tailings dams Vicious accidents such as landslides and mudslides in dumps, landslides and mud-rock flows occur from time to time. In addition, due to problems left over...
