Problems solved by technology

[0004] The inclined plate for simulating the slope in the device needs to be installed before the test (otherwise the model cannot be installed), and the inclination angle of the slope cannot be changed during the whole test
Therefore, in the course of a single test, it is more difficult to make the landslide occur on the slope, and it often takes multiple experiments to grasp the influence of the slope angle on the specific landslide, and the efficiency of the experiment is low.

Description

Technical field [0001] The invention belongs to the technical field of experimental devices for geotechnical centrifuges, and in particular relates to an experimental device for simulating landslides and debris flows applied to geotechnical centrifuges. Background technique [0002] In the natural environment, mountains or man-made dams are affected by water erosion, geological movement, and human activities, which will cause collapse, slipstream and other phenomena, which will cause landslides, debris flows and other geological disasters. If such geological disasters occur in remote areas, they will cause changes in the natural environment; if they occur at construction sites, towns and villages and other population clusters, they will cause significant loss of personnel and property. In order to reduce the losses caused by landslide and debris flow disasters, researchers need to study the mechanism and process of the disaster to improve the accuracy of disaster forecasting and ...
