Landslide surge simulator

Abstract

The invention discloses a landslide surge simulation device, which includes a slideway, the slideway is spliced ​​by multiple sections along the slideway, and a wave height meter is arranged between two adjacent sections of the slideway along the course, and the slideway The upstream of the road is provided with a water inlet device, and the downstream is provided with a water outlet device. A landslide simulation system is fixed on one side of the upstream of the slideway, and a simulated sliding body is placed on the landslide simulation system. The landslide simulation system includes a height adjustment system , the top of the height adjustment system is connected with a plurality of conveyor belts, and the roughness of each conveyor belt surface is different, and the conveyor belts are connected with the control system, and the simulated sliding body includes a flexible box, and the flexible box is equipped with There are a plurality of small balls, and signal transmitters are arranged in the small balls. The invention can accurately control the inclination angle of the sliding surface, the water entry speed of the sliding body, and the sliding sequence of the sliding body, and accurately measure the climbing height and propagation distance of the surge caused by the landslide. The device is simple and easy to operate, low in cost, and high in test efficiency. High precision.

Description

technical field [0001] The invention relates to a simulation device, in particular to a landslide surge simulation device. Background technique [0002] The analysis of the movement mechanism of accumulation body landslides has always been an important problem to be solved urgently at home and abroad. The unstable sliding of sliding soil along the sliding surface will cause various secondary and derivative disasters, such as surges and damming, which seriously threaten the safety and stability of the project and cause greater economic losses. Therefore, the analysis of the movement mechanism of the landslide slide zone is of great significance for engineering safety and disaster prediction and early warning. Usually, the main methods of landslide mechanism research include theoretical analysis, model test, numerical simulation, etc., and physical model test is one of the most direct research methods. [0003] At present, the existing physical models for simulating the slid...

AI Technical Summary

Problems solved by technology

[0004] (1) The slope is single and the slope height is fixed, which cannot adapt to different types of landslides;

[0005] (2) The method of changing the water entry speed of the slide body by changing the slope angle cannot accurately control the slide body movement form, sliding sequence and water entry speed of the slide body during the sliding process;

[0006] (3) The sliding body slides down by its own weight to generate sliding force. When the friction coefficient of the sliding surface is too large, problems such as non-slip or incomplete sliding often occur
