Experiment device for measuring motion characteristics of slope rolling stone

Abstract

The invention relates to an experiment device for measuring the motion characteristics of a slope rolling stone. The device comprises a three-dimensional slope model, a bottom plate, a protective screen, force sensors, a data acquisition system and high-speed cameras, wherein the three-dimensional slope model is disposed on the bottom plate in an inclined manner, and the lower end of the three-dimensional slope model is connected with the bottom plate. The protective screen is disposed at the tail end of the three-dimensional slope model, and both ends of the protective screen are connected with protective columns, wherein the protective columns are connected with supporting columns through cables. The force sensors are disposed at the tail ends of the cables, and the high-speed cameras are respectively located at the left and right sides of the three-dimensional slope model and at an upper part. The device is simple in structure, is simple in operation, is novel in test method, is objective and accurate in test data, can measure the movement characteristics of rolling stones at the slopes in various geometric shapes, and effectively solves an experimental error caused by a traditional slope form. An obtained analysis result can be used for the cause study of the movement mechanism of the rolling stone, and provides a scientific basis for the disposal of dangerous rock masses and the installation of protective structures.

Description

technical field [0001] The invention relates to an experimental device, in particular to an experimental device for measuring the movement characteristics of rolling rocks on a slope. Background technique [0002] Slope rolling stones are a common natural disaster in mountainous areas, especially in road network traffic lines, mountainous towns, hydropower stations, transmission lines and other places in western mountainous areas of my country. Its own physical and mechanical properties have a great influence, and its occurrence has high frequency and uncertainty, which often poses a major threat to engineering structures, people's lives and property within its affected range, and causes huge losses. With the acceleration of infrastructure construction in mountainous areas, research on the characteristics of rolling rocks on slopes can no longer be ignored. How to prevent and manage disasters has attracted great attention and widespread attention from government departments, ...

AI Technical Summary

Problems solved by technology

In order to facilitate the calculation of slope angle, some idealized special values ​​are often selected. Although this helps to simplify the actual complex problems and greatly reduce the modeling and calculation time, the conclusions obtained are not consistent with the actual situation or even very different. It is difficult to predict the bouncing height, speed and impact force on the protective net when the rolling stone falls, so it is difficult to choose the type of protective net, determine the height of the protective net and the setting angle
