Analog test system for start, movement and impact of slope rolling stone

Abstract

The invention discloses an analog test system for start, movement and impact of a slope rolling stone. The system is composed of a slope rolling stone slide model, a rolling stone impact test system,a first rolling stone motion recording system, a second rolling stone motion recording system, a test data processing system, a number of connecting lines and an experimental rolling stone. The sloperolling stone slide model, the rolling stone impact test system, the first rolling stone motion recording system, the second rolling stone motion recording system and the test data processing system are arranged on a worktable respectively, and the model and the systems are connected with the test data processing system through a number of connecting lines. According to the invention, the system can be applied to simulate the rolling stone movement on a slope type combining different slope grades; the slope rolling stone slide model has high applicability, can be reused to realize whole courseautomation and integration of rolling stone starting, movement recording, impact testing and data processing, has the advantages of constant monitoring and strong anti-human interference ability, andprovides a scientific basis for the prevention and control of rolling stones.

Description

technical field [0001] The invention relates to a simulation test system, in particular to a simulation test system for start-up, movement and impact of rock rolling on a slope, and belongs to the technical field of geological disaster prevention and control. Background technique [0002] With the rapid development of my country's economy and the effective implementation of the western development strategy, major lifeline projects such as roads, railways, and water conservancy projects have been continuously implemented in the western mountainous areas. Due to the intensification of human activities during construction and the frequent occurrence of earthquakes in the western mountainous areas , will inevitably cause serious problems such as loosening of geological bodies along the above-mentioned project and instability of collapsed and dangerous rock masses. [0003] The instability of the collapsed dangerous rock mass seriously threatens the safety of engineering buildings...

AI Technical Summary

Problems solved by technology

The numerical simulation method can simulate the movement characteristics of rolling stones under different working conditions, but due to the corresponding simplification of material properties and boundary conditions, the simulation reliability is low

The field test method is a method of field simulation, which is expensive, difficult to implement, and not universally applicable

The indoor test method is a more commonly used method in recent years, but the equipment and devices used are highly disturbing, low in universality, and low in integration.
