Multifunctional test platform for landslide impact strength

Abstract

The invention discloses a multifunctional test platform for landslide impact strength, comprising a slide channel, an accumulating channel, a supporting adjusting device arranged at the bottom of theslide channel, landslide impact sensors arranged in different positions in the accumulating channel, a data collection device arranged outside a test model channel and connected with the landslide impact sensors, and a rainfall simulator arranged above the slide channel; the slide channel and the accumulating channel are uniform in sectional size and are each formed by assembling a plurality of unit model channels 1 m in length and 1 m*1 m in inner diameter. The multifunctional test platform for landslide impact strength has the advantages that multifunctional landslide physical simulation experiments, such as rainfall-induced landslide mechanism analysis, landslide rock-soil deformation monitoring analysis, landslide speed monitoring and landslide impact test analysis can be carried out,and an experimental apparatus is simple and firm, convenient to disassemble and assemble; the multifunctional reusable test platform based on based on multiple variables is suitable for the scientificresearch and utilization of landslide disaster, and is worthy of popularization and application.

Description

technical field [0001] The invention relates to a geological disaster simulation test experiment platform, in particular to a multifunctional landslide impact strength test platform. Background technique [0002] my country is a country prone to geological disasters, with many types, wide distribution and high density, especially landslide disasters. At present, the landslide hazards and potential threats in China account for about 25% of the country's land area, and the losses caused by landslide disasters are hundreds of millions every year, bringing huge losses to the country and people's lives and property. Over the years, scholars at home and abroad have done a lot of research on the formation mechanism of landslides, monitoring and early warning, and risk assessment, and have achieved fruitful results. However, there are still many difficulties in the quantitative analysis of the consequences of landslide disasters and the quantitative assessment of landslide risk. In...
