A Physical Experimental Model and Method of Rock Slope Collapse

Abstract

The invention provides a rock slope collapse physical experiment model and method. On the basis of the basic rock slope collapse physical model experiment, the similarity ratio calculation is carried out through the similarity theory, and the bolt model and the anchor net component are made. The main body of the slope is mainly made of unit slabs. The jointing phenomenon of the rock slope is formed through the unit plate; a high-precision stress monitoring unit is produced to monitor the axial force value of the bolt model. The stress monitoring unit can monitor the axial force change of the bolt in real time. The monitoring principle and engineering application The NPR bolt axial force monitoring equipment is similar to that of NPR, and its monitoring data can provide a certain reference for engineering practice; in order to more comprehensively obtain the displacement changes of each part of the rock mass when the rock collapse disaster occurs, the rock slope is simulated The front side of the module is monitored by a deformation monitoring unit, and the strain displacement data of the experimental surface is obtained through speckle technology.

Description

technical field [0001] The invention belongs to the technical field of rock slope collapse experiments, and in particular relates to a rock slope collapse physical experiment model and method. Background technique [0002] In my country, the rock slope collapse disaster is a high-frequency geological disaster. The disaster-causing process of the rock slope is very short, and it poses a huge threat to the life and property safety of the people in the disaster area. However, most data on rock slope collapse disasters are collected on site after the catastrophe occurs, and various parameters of the catastrophe process are difficult to obtain. great difficulty. The physical model test can restore the process of rock slope catastrophe to a certain extent, and can also monitor the physical and mechanical parameters of the key parts of the model under stress, which is helpful for the study of rock slope collapse disasters. At present, most of the physical model tests of collapse ...

AI Technical Summary

Problems solved by technology

At present, most of the physical model tests of collapse are the research on the failure mechanism of rock mass collapse, and the damage mechanism of the collapse disaster is only studied. There is no physical experimental model that can deeply study the combination of support and reinforcement of the collapse disaster and the monitoring and early warning system.
