Problems solved by technology

In addition, the on-site measurement of dangerous rock collapse takes a long period and requires a lot of manpower and material resources. It is severely restricted by the site conditions and has great limitations.
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

Abstract

The invention relates to the technical field of rock mass stability, and discloses a slip type dangerous rock collapse test simulation device. The test simulation device is characterized in that a movable vertical loading device is arranged at the top of the test device and applies a vertical load to a dangerous rock body, the opening degree of a structural surface between the dangerous rock and amother rock is increased, the test device is provided with a bearing platform clamp to stabilize the mother rock, and a control panel on a platform plate of the test device adjusts a load numerical value. The movement change of the rock mass is observed through a total station and a full-field strain measurement system. The device can simulate structural plane evolution characteristics and instability collapse rules of the natural dangerous rock mass under the action of self-gravity, and the whole process overcomes the defects of long time and high cost of traditional on-site monitoring. Thedevice has the advantages of being simple to operate, convenient to observe, short in test time, low in cost and the like, collapse of dangerous rock bodies of various sizes can be simulated by the test device, and sliding type dangerous rock collapse test simulation under various structural surface conditions is met.

Description

Technical field [0001] The invention is a sliding type dangerous rock collapse test simulation device, and relates to the technical related fields such as the stability of the dangerous rock and the failure mechanism of the dangerous rock collapse. Background technique [0002] Dangerous rock masses are one of the main geological disasters in mountainous areas, causing economic losses of up to billions every year, and have a great impact on the production and life of mountain residents. Dangerous rock masses formed by bare hard rock are subject to gravity and are affected by factors such as earthquakes, rainfall or artificial activities. They can easily roll or fall from heights, bury roads and railways, interrupt traffic, and destroy buildings, causing serious damage. Property damage and casualties. The device for simulating dangerous rock collapse is to collect data on the entire process of dangerous rock collapse in the real world on the basis of examples. It is a model test ...
