Problems solved by technology

But mudslides occur less frequently, making it difficult to track ongoing mudslides
In addition, the characteristics of debris flow in different periods are quite different, and it is difficult to predict future debris flow parameters through the movement and accumulation parameters of individual periods of debris flow

Abstract

The invention discloses a debris flow moving and accumulating process simulation experiment system. The debris flow motion and accumulation process simulation experiment system comprises a conveyor belt, elevators, a stirring box, a work platform, a water tank, a connection groove, straight circulation grooves, a bent circulation groove, a circulation groove valve, hole pressure testing devices, a bayonet, a flow-speed and flow testing device, an impact force testing device, a high-speed camera, an accumulation area, a column base, a water drawing device and a receiving host. Solid particles with certain granularity compositions are prepared into a debris fluid with a certain slurry concentration by the conveyor belt, the elevators, the stirring box, the work platform, the water tank and the water drawing device, and the column base is used for ensuring the stability of the work platform. The circulation groove valve is used for controlling the debris fluid to move in the straight circulation grooves or the bent circulation groove. The elevators are used for controlling the moving gradient of the debris flow. Moving and accumulating processes and dynamics parameters of the debris flow are tested and monitored by the hole pressure testing devices, the flow-speed and flow testing device, the impact force testing device and the high-speed camera.

Description

technical field [0001] The invention relates to a mud-rock flow simulation device, in particular to a mud-rock flow movement and accumulation simulation experiment system. Background technique [0002] Debris flow is a common geological disaster in mountainous areas, which has the characteristics of sudden outbreak and huge destructive ability. Debris flows often carry huge boulders, which have a strong impact and endanger the lives and property of people passing through the area. Therefore, predicting the dynamic parameters and accumulation characteristics during the movement of debris flow has strong guiding opinions for disaster prevention and mitigation of debris flow. [0003] At present, the movement and accumulation parameters of debris flow are mainly obtained by on-site monitoring or actual measurement. But mudslides occur so infrequently that it's hard to keep track of ongoing mudslides. In addition, the characteristics of debris flow in different periods are qu...
