Adjustable multifunctional landslide river stacking and disaster-caused range test equipment

Abstract

The invention provides adjustable multifunctional landslide river stacking and disaster-caused range test equipment, which comprises a river model device, a landslide model device, a driving device and a water flow velocity control system, wherein the river model device comprises a bottom plate, two ramps and two side plates; the two side plates are mounted at the front and rear ends of the bottomplate; the two ramps extend along a front-back direction, are located between the two side plates, can slide along a left-right direction and is mounted on the side plates in a manner of rotating around the bottom end; the landslide model device is located on the right side of the river model device; the gradient of a landslide can be adjusted; the driving device is opposite to the upper end of the landslide model device and is used for driving a landslide test sample to slide downwards along a landslide bottom plate; and the water flow velocity control system is used to control the water flow velocity in the river model device. The adjustable multifunctional landslide river stacking disaster-caused range test equipment provided by the invention has the beneficial effect that a comprehensive research on influence factors of multiple aspects on landslide river stacking and a disaster-caused range is realized, and various influence factors of the entry speed of the landslide, the waterflow velocity of a river, a river width, the gradients of both shores and the like are simultaneously considered.

Description

technical field [0001] The invention relates to the technical field of landslide model simulation devices, in particular to an adjustable and multifunctional landslide channel accumulation disaster-causing range test equipment. Background technique [0002] The accumulation of disaster landslides in the river has a very significant impact on the natural environment, human life and construction projects. Landslides accumulate in the river, and the increase of silt thickness is easy to block the formation of barrier dams, causing the rapid rise of the water level and endangering the safety of the downstream; at the same time, during the occurrence of the landslide, the water entering will cause a huge impact, and the formed surge will have a strong impact on the buildings on the bank slope. and people's life and property; in the reservoir area, thick landslide material is deposited in the channel after the reservoir is impounded, and it is easy to trace back to the source when...

Landslides accumulate in the river, and the increase of silt thickness is easy to block the formation of barrier dams, causing the rapid rise of the water level and endangering the safety of the downstream; at the same time, during the occurrence of the landslide, the water entering will cause a huge impact, and the formed surge will have a strong impact on the buildings on the bank slope. and people's life and property; in the reservoir area, thick landslide material is deposited in the channel after the reservoir is impounded, and it is easy to trace back to the source when the water level of the reservoir drops, and as the water level drops, the deposited material is prone to collapse , increase the storage capacity, and affect the safe operation of the hydropower station. After the reservoir is impounded, the bank slope collapses and the mud and sand accumulated in the debris flow outbreak is close to, or even exceeds the storage capacity of the dead water level, the reservoir will lose its regulation and power generation functions, which directly affects the safe operation of the reservoir.
