Abstract

The present invention relates to the field of geological disaster simulation tests, in particular to a slope test system, in which a groove is provided at the bottom of the transparent box close to the extruding device, and a drain is provided on the side wall of the transparent box corresponding to the groove , the slope model is preset with a hose with holes to simulate the seepage state of the slope model; the rainfall device is used to simulate the rainfall state, and the vibration device is used to vibrate the slope model; the extrusion device is set opposite to the vibration device On the other side of the transparent box, the extrusion device is used to laterally extrude the slope model to change the cohesive force of the slope model; the monitoring device monitors the slope model through image acquisition, and processes and analyzes the image information , which can adjust the bonding force of the slope model and the vibration intensity of the slope model according to the test requirements, and conduct tests on the slope model under the conditions of vibration, rainfall, high humidity and seepage.

Description

technical field [0001] The invention relates to the field of geological disaster simulation tests, in particular to a side slope test system. Background technique [0002] Among all kinds of natural disasters, landslides and debris flows cause serious losses. There are side slopes around traffic roads, river bed dams and mines in mountainous areas. Landslides and debris flows are more likely to occur on slopes under vibration and rainfall conditions. [0003] The existing slope test system can only test the prefabricated slope model, but cannot change the structural strength of the slope model, and the slope test has certain limitations. Contents of the invention [0004] The object of the present invention is to provide a kind of slope test system, it can adjust the cohesive force of the slope model and the vibration intensity that the slope model is subjected to according to the test needs, and carry out the slope model under the conditions of vibration, rainfall, high h...
