Rock slope collapse physical experiment model and method

Abstract

The invention provides a rock slope collapse physical experiment model and method; on the basis of a basic rock slope collapse physical model experiment, similarity ratio calculation is carried out through a similarity theory, an anchor rod model and an anchor net assembly are manufactured, and a rock slope main body is mainly manufactured by stacking unit plates. The joint physicochemical phenomenon of a rock slope is formed through the unit plates; a high-precision stress monitoring unit is manufactured in a matched mode to monitor the axial force value of the anchor rod model, the stress monitoring unit can monitor the axial force change of an anchor rod in real time, the monitoring principle is similar to that of NPR anchor rod axial force monitoring equipment in engineering application, and monitoring data can provide certain reference for engineering practice; for more comprehensively obtaining displacement changes of rock bodies of all parts when collapse disasters happen to therock slope, a deformation monitoring unit is adopted on the front side face of a rock slope simulation module for monitoring, and strain displacement data of the experimental surface are obtained through a 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.
