Simulation test platform for high-altitude landslide debris flow anti-impact blocking structure

Abstract

The invention discloses a simulation test platform for a high-altitude landslide debris flow anti-impact blocking structure, and relates to the technical field of geological experiments and geologicaldisaster prevention and control. The platformcomprises hoisting equipment (1), a sliding block (2), a first-stage sliding groove support (3), an inclined hydraulic lifting platform (7), an automatichydraulic lifting platform (8), a protective wall (9), a ground anchor trench (11), a drag reduction recycling pool (12) and a multi-stage sliding groove. The multi-stage sliding grooves comprise thefirst-stage sliding groove (4), the second-stage sliding groove (5) and the third-stage sliding groove (6) from top to bottom. The platformcan be built in a nearby place, and pile forest dams, pile beam dams and other test models can be installed in ground anchor ditches; large-scale and even full-scale impact tests of various anti-impact blocking structures can be achieved on the same platform, the test site is not limited by the site environment, anti-impact blocking tests and data acquisition can be conveniently and repeatedly conducted, and the cost can be controlled. According to the invention, various automatic hydraulic lifting platforms are additionally arranged, so that the movement of debris flow under various angle combination working conditions can be simulated.

Description

technical field [0001] The invention relates to the technical field of geological experiments and prevention and control of geological disasters, in particular to a high-level landslide debris flow anti-shock blocking structure simulation test platform. Background technique [0002] High-level landslide debris flow is a typical chain-type geological disaster in the high mountain area of ​​my country. The high-level landslide disintegrates during the movement to form a high-speed debris flow, with high-content boulders in the middle, which has the characteristics of high energy and high impact force, and can often cause Catastrophic event, causing severe loss of life and property. [0003] At present, the usual method of blocking high-level landslide debris flow is to use gravity dams, grid dams, pile forest dams, pile beam dams, etc., which have been widely used in high-level debris flow blocking projects. And the pile-beam dam has the advantages of separating fluid and soli...

AI Technical Summary

Problems solved by technology

[0006] Foreign high-level landslide debris flow and retaining structure tests basically use existing hillsides to carry out related motion and impact tests. The disadvantage is that the test site is easily restricted by the site environment.

Moreover, the test site is often far away from the urban area, and the cost of each test is relatively high and takes a lot of time.
