Landslide surge simulation device

Abstract

The invention discloses a landslide surge simulation device which comprises a slide way, the slide way is formed by splicing multiple along-the-way slide ways; a wave height meter is arranged between every two adjacent along-the-way slide ways; a water inflow device is arranged on the upstream of the slide way; a water outflow device is arranged on the downstream of the slide way; a landslide simulation system is fixed to one side of the upstream of the slide way; a simulated sliding body is placed on the landslide simulation system; the landslide simulation system comprises a height adjusting system; the top of the height adjusting system is connected with a plurality of conveying belts; the roughnesses of the surfaces of the conveying belts are different; the conveying belts are all connected with a control system; the simulated sliding body comprises a flexible box; a plurality of small balls are arranged in the flexible box; and signal emitters are arranged in the small balls. With the landslide surge simulation device of the invention adopted, the inclination angle of a sliding surface, the water entry speed of the sliding body and the sliding sequence of the sliding body can be accurately controlled, and the rise and propagation distance of the surge caused by the landslide can be accurately measured. The landslide surge simulation device is simple, easy to operate, low in cost, high in test efficiency and high in 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...

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
