Abstract

The invention provides a physical modeling experiment device for a multifunctional high-speed remote landslide dynamic process. The physical modeling experiment device comprises a support base, an upper sliding section, a transition section and a lower sliding section, wherein the upper sliding section, the transition section and the lower sliding section are successively connected with each other; the support base is arranged as a height adjusting mechanism; the top end of the height adjusting mechanism is connected with the lower surface of the inlet end of the upper sliding section; the upper sliding section comprises an upper sliding slot, a baffle and a rotating connector; the baffle is mounted in the upper sliding slot; the transition section is arranged as an arc-shaped slide slot matched with the rotating connector; the transition section is hinged with the rotating connector; the lower sliding section comprises a lower sliding slot and an adjusting module; one slot wall of the lower sliding section is hinged with the transition section while the other slot wall is connected with the transition section through the adjusting module. The device provided by the invention can be used for implementing a physical modeling experiment for the multifunctional high-speed remote landslide dynamic process; the three factors of landslide height, landslide volume and topographic condition are mainly contained; the topographic condition factor includes gradient, base and sliding path direction; the reciprocating test can be performed according to different topographic conditions.

Description

technical field [0001] The invention relates to a physical model test device for a landslide dynamic process, which belongs to the technical field of geological disaster model tests. Background technique [0002] The dynamic process of high-speed and long-distance landslides has always been a hot issue studied by scholars at home and abroad. According to the evolution law of high-speed and long-distance landslides, the dynamic process can be divided into three stages: departure, short-range and long-distance. The whole process of the sliding body from the shear outlet to the final stop of accumulation involves two stages, short-range and long-range, which can be collectively referred to as the motion accumulation stage. Due to the unique dynamics of the high-speed long-distance landslide movement and accumulation process, it can slide over a long distance at a very high speed in a short period of time, and it will often evolve into a catastrophic event on the path of the la...

Problems solved by technology

[0006] At present, when landslide simulation experiments are carried out indoors, most experiments are designed in conjunction with the geological data of a certain landslide event. Although this method can be relatively accurate, there are often the following problems in this experimental method: (1) The function is single, and generally only one influencing factor can be studied for a specific device; (2) the test period is long and the cost is high; (3) the reusability is poor; (4) for large-scale physical model test devices, it is difficult to disassemble and not Easy to move and assemble
