Abstract

The invention provides a side slope three-dimensional bottom friction testing device and belongs to a testing device for simulating side slope damages. The side slope three-dimensional bottom friction testing device is composed of a side slope model, a friction device, a horizontal loading device and a basic framework, wherein the side slope model can be an entity with a plurality of steps and is packed in a rectangular box body; the friction device is arranged at the bottom of the side slope model; and the horizontal loading device is arranged at the back part of the side slope model. By utilizing the friction device at the bottom and the loading device at the back part, a shear force generated when a side slope is damaged is simulated, so that a condition that the three-dimensional side slope model is damaged under natural or manual conditions is simulated. The testing device provided by the invention is simple in structure and low in manufacture cost, can be used for clearly observing a damaging manner of the side slope, and also can be used for relatively accurately determining damage data and effect of the simulated side slope model.

Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a three-dimensional test device for simulating slope damage. Background technique [0002] Among all kinds of natural disasters, landslides, collapses and collapses of slopes are huge geological natural disasters. In my country, the economic losses caused by landslides are very huge every year, and the economic losses caused by landslides in open-pit mine slopes cannot be ignored. . Therefore, the study of the mechanism of landslide failure has become a very important research topic. The failure of the slope is caused by the shear stress exceeding the shear strength of the slope. For the different forms of slope failure caused by the shear stress at different positions, and the same failure form but different failure locations have a significant impact on the stability of the slope. The analysis provides very valuable data. Among them, the experimental analysis of using the bot...
