Device and method for monitoring landslide surge height and dynamic pressure with adjustable angle

Abstract

The invention relates to the technical field of geological disaster and water conservancy experimental equipment, in particular to an angle-adjustable monitoring device and method for the landslide surge height and dynamic pressure. Main flat plates and wave bearing plat plates which have different lengths are connected to different fixing points of an experimental water tank, and then the slope of the main flat plates is adjustable, the slope of the wave bearing flat plates can be flexibly adjusted, and the requirements of the experimental device for different slope changes can be met, so that the experimental simulation results are closer to reality. The experimental water tank is made of transparent organic glass, and a wave height meter is arranged in the center of the water tank. Thechange curve of the surge wave height with time is obtained through the wave height meter. A high-speed camera and the wave height meter can clearly record the propagation process of the surge in thewater tank and the wave height changes of the surge. Pressure sensors are arranged on the wave bearing flat plates, are used for pressure data acquisition, and can record the pressure change of the wave bearing flat plate during the experiment. The experimental device is simple, and is easy to operate and maintain.

Description

technical field [0001] The invention relates to the technical field of geological disasters and water conservancy experiment equipment, in particular to an angle-adjustable monitoring device and method for landslide surge height and dynamic pressure. Background technique [0002] Landslide surge refers to the sudden sliding of slope rock and soil and the interaction with water body to cause waves, and its destructive intensity sometimes exceeds that of earthquake-induced tsunami. In the edge areas of rivers and lakes, large-scale landslides pouring into the water will inevitably cause serious problems, such as threatening passing ships and causing suspension of navigation; destroying hydraulic structures around the reservoir and causing dam collapse; destroying downstream farmland houses and threatening the surrounding area of ​​the reservoir The safety of life and property of residents, etc. There are many safety accidents caused by landslide surges. For example, in 1762, ...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the above technical problems, the present invention provides a monitoring device and method for the height of landslide surge and dynamic pressure with adjustable angle, which can not only solve the problem that the angle of the falling body into the water slope cannot be solved in previous similar experiments. In addition, a wave-bearing slope with an adjustable slope can be designed, which can be used to study the impact force and climbing height of swell waves propagating to shores with different slopes; at the same time, high-speed cameras, wave height meters, etc. Measuring instruments observe and measure the propagation process of swell and measure the height and propagation speed of swell
