Problems solved by technology

[0005] However, due to the uncertainty of landslide mass state, sliding velocity, sliding mass entry angle, and surge propagation direction, in previous indoor hydraulic simulation tests, one device could only study the influence of one variable on surge. Causes the dilemma of increasing investment but few test results

Abstract

The invention discloses a model test device and method for studying a landslide surge propagation rule and a climbing effect. The model test device comprises a conveying device, a landslide mass model, an experimental water tank, a waveform test device, a climbing effect slope shape device and the like. The conveying device comprises a conveying belt, a lifting bearing platform, an engine and the like. The landslide mass model slides into the experimental water tank through the conveying belt; the water tank is fixed above the water tank bearing platform; the waveform test device comprises a high-speed image recorder and a wave measurer which are respectively arranged on the side surface and the bottom of the experimental water tank, and a terminal is connected with the receiving device; the climbing effect slope shape device is fixed in the experimental water tank during a climbing effect experiment; and the pressure sensing device is placed on the surface of the slope shape device. According to the invention, the propagation law of surges in different propagation directions in a horizontal tank and the propagation law of surges in an inclined water tank caused by one-time or continuous multi-time sliding of landslide bodies with different states, different sliding speeds and different water entry angles can be simulated through the test device.

Description

technical field [0001] The invention relates to the technical field of landslide surge geological disaster test and water conservancy and hydropower engineering test equipment, in particular to a model test device and a test method for studying landslide surge propagation law and climbing effect. Background technique [0002] Water conservancy and hydropower projects are mostly located in deep-cut canyon landforms, and the slopes in the reservoir area are characterized by large numbers, steep slopes, and large volumes. Once it loses stability, huge landslide surges will be generated once or several times in succession, causing water waves to propagate in different directions, and even climb to the opposite bank of the river. [0003] Research results on surge energy dissipation such as the invention patent (publication number CN110188443A) applied by Hohai University discloses a model test device for researching landslide surge energy dissipation effect and wave height predi...
