Dangerous rock collapse test simulation device

Abstract

The invention discloses a falling type dangerous rock collapse test simulation device, and relates to the technical field of rock mass stability. The device can simulate structural plane evolution characteristics and instability collapse rules of the dangerous rock mass in the nature under the action of gravity. A vertical load is applied to a dangerous rock body through a loader, the rock body stress begins to change, the rock body gradually moves, the opening degree of a structural surface between the dangerous rock and a mother rock is increased, a control panel adjusts a load numerical value, the rock body movement change is observed through a total station and a full-field strain measurement system, and the mother rock is stabilized through a clamp. The whole process overcomes the defects of long traditional on-site monitoring time and high cost, and dangerous rock mass collapse phenomena under various working conditions can be conveniently simulated. The falling type dangerous rock collapse test simulation device has the advantages of being easy to operate, convenient to observe, short in test time, capable of being repeatedly operated, low in cost and the like, collapse of dangerous rock bodies of various sizes can be simulated, and falling type dangerous rock collapse test simulation under various structural surface conditions can be met.

Description

technical field [0001] The invention relates to a drop-type dangerous rock collapse test simulation device, which relates to technical related fields such as the stability of dangerous rock and the damage mechanism of dangerous rock collapse. Background technique [0002] The instability and failure of dangerous rock is a common geological disaster. With the construction of a large number of infrastructure and reservoir resettlement projects in my country, dangerous rock collapse disasters have become an important part of disaster prevention and control. Dangerous rocks pose a greater threat to the safety of life and property of residents below the mountain slope and road traffic, and have become a major threat to the people. A major source of danger for life safety, it is imminent to effectively prevent the disaster caused by the collapse of dangerous rocks. The device for simulating dangerous rock collapse is to collect data on the whole process of dangerous rock collapse ...

AI Technical Summary

Problems solved by technology

[0003] For a mechanical problem with many influencing factors, complex physical process and serious human disturbance, it is difficult for people to understand all the factors affecting the problem clearly, but they cannot quickly and accurately describe the whole process of dangerous rock collapse catastrophe, so It is often impossible to carry out precise theoretical analysis of the problem

However, the inherent period of on-site measurement is long, consumes a lot of manpower and material resources, and is severely restricted by on-site conditions. interaction, increasing the difficulty of field survey
