Experimental device for simulating slope rockfall trajectory

Abstract

The invention discloses an experimental device for simulating a slope rockfall trajectory. The experimental device comprises a slope simulation structure, a shell, a rockfall sample and a rockfall release device, the slope simulation structure is arranged in the shell; the shell comprises a steel frame and a plurality of organic glass partition plates, and the falling stone releasing device comprises a sliding block, a height control device and a releasing mechanism; when the slope raising test block is used for experiments, only the slope raising test block needs to be replaced for different slope shapes, so that the slope raising speed can be increased, and the loss of related materials is reduced; the falling rock releasing device is simple in structure and easy to assemble, the falling rock releasing device can be further adjusted according to the actual position of the slope dangerous rock mass, and the horizontal position of falling rocks can be adjusted through sliding of the sliding blocks in the sliding grooves; and the purpose of adjusting the release height can be achieved by fixing the slide block on the clamping holes with different heights between the two positioning rods.

Description

technical field [0001] The invention relates to the technical field of slope engineering experimental equipment, in particular to an experimental device for simulating rockfall tracks on a slope. Background technique [0002] Rockfall refers to the sudden downward collapse of dangerous rock mass or dangerous rock on the slope after exceeding the critical balance point, and rolls down the slope through one or more combinations of rolling, collision, rebound, jumping or sliding motion. , a dynamic evolution process until it falls to flat ground, rivers, reservoirs or obstacles and stops moving. And when there are human activity areas such as residential areas and construction sites under the falling rocks, it may cause huge casualties and property losses. Therefore, in actual engineering, it is necessary to understand the trajectory and impact range of slope rockfall, and the experimental device for slope rockfall simulation can clearly collect the corresponding trajectory, p...

AI Technical Summary

Problems solved by technology

[0005] 1. The in-situ test technology simulates slope rockfall. Although the simulation of trajectory and impact range is more accurate, the cost is too high and it is not suitable for large-scale use. After the test, it is easy to disturb the balance of the slope, causing the dangerous rock mass to roll down in advance ;

[0006] 2. Due to the differences in the slope shape and rock parameters of different slopes, it is necessary to re-make all the slopes for each simulation. The construction period is long, the cost is high, and it is easy to cause waste of materials;

[0007] 3. The relevant devices that can adjust the angle of the slope cannot accurately simulate the shape of the slope. Due to too much simplification, the rationality of the obtained results and the consistency with the actual situation need to be verified, and the reference is weak

[0008] 4. The release height of the dangerous rock test piece cannot be adjusted; and the release lateral position of the dangerous rock test piece can only be realized by moving the dangerous rock test piece. When there are too many dangerous rock test pieces, it is inconvenient to move
