Problems solved by technology

However, after more than ten years of effect observation, it was found that most of the treatment projects did not achieve the expected results. The root cause was the inaccurate determination of the movement path of debris flow and the low accuracy of calculation of debris flow impact force.

Abstract

The invention provides a device for a debris flow impact test. The device comprises a base, a debris flow slurry supply device, a debris flow solid-phase particle supply device, an upper flow-guidingplate, a middle flow-guiding plate, a lower flow-guiding plate, four telescopic support columns, multiple impact sensors, multiple acceleration sensors and a conduit. The device provided by the invention has the advantages that the device for debris flow impact test can simulate the flowing process of the debris flow fluid and acquire the corresponding data, so that the people can research the debris flow movement evolution rule and the debris flow gully impact load change rule.

Description

technical field [0001] The invention relates to a test device, in particular to a device for debris flow impact test. Background technique [0002] my country is a mountainous country with frequent debris flow disasters. The total mileage of highways located in high-incidence areas of debris flow reaches 1.5 million kilometers (as of the end of 2017). Road-breaking disasters caused by debris flow, such as subgrade erosion, concrete pavement suspension, road silting, and bridge pier foundation erosion damage, have the characteristics of "multiple points, wide area, and severe disasters". It has become a national demand to improve the technical level of debris flow breakway disaster reduction as soon as possible. For a long time, scholars at home and abroad have carried out continuous, in-depth and systematic research on the transport and dynamics of debris flow, and have obtained fruitful research results in aspects such as debris flow velocity, curve superelevation, and imp...
