Laboratory experiment system for simulating sliding process of landslide along three-dimensional terrain

Abstract

The invention discloses a laboratory experiment system for simulating the sliding process of landslide along three-dimensional terrain. The laboratory experiment system for simulating the sliding process of landslide along three-dimensional terrain comprises a control device, a chute device, an observing unit and a linking unit, wherein the observing unit is used for recording and simulating the flooding track of a landslide body; the linking unit is used for enabling the observing unit and the control device to operate synchronously; the chute device comprises a horizontal chute and a plurality of slope chutes which are connected from head to tail; two adjacent slope chutes can be connected rotatably; chute lifting devices for adjusting the heights of the horizontal chute and each slope chute are arranged under the horizontal chute and each slope chute; the control device comprises a control table, a control table lifting device for supporting and adjusting the height of the control table, a driving part arranged on the control table as well as a starting device; the bottom of an actuating part of the starting device is arrange in the slope chutes and is tightly matched with the slope chutes; the driving device drives the actuating part of the starting device to act so as to simulate the flooding of a landslide body; an included angle between each slope chute and the horizontal level and an inclined angle between two adjacent slope chutes can be adjusted randomly, so that the slope path becomes universal, and is wider in applicability.

Description

technical field [0001] The invention relates to a simulation experiment system, in particular to a simulation experiment system for a sliding process of a landslide along a three-dimensional terrain, in particular to an indoor experiment system for simulating a sliding process of a landslide along a three-dimensional terrain. Background technique [0002] The landslide simulation experiments abroad began in the 1960s, and the initial application of the landslide model was in the landslide of the Vaillant Reservoir in Italy. By the 1970s, foreign research institutions such as the United States and Japan began to use artificial rainfall as an inducement to study the formation mechanism of rainfall-type landslides. [0003] At the end of the 20th century, the method of indoor simulation of rainfall to study landslides began to be used by domestic scholars. By using similarity theory, experimental studies of landslide problems can be carried out in the laboratory. Song Keqiang...

AI Technical Summary

Problems solved by technology

[0006] 1. The sliding bed simulated by the chute is mostly a single straight line segment, which cannot simulate a curved landslide track

[0007] 2. The start of the landslide mostly depends on the pouring after the gate of the upper device is opened, which cannot simulate the characteristics of the original landslide

[0008] 3. There is a lack of research on the disaster impact of high-speed landslides on the area below the slope, including the study of the impact area of ​​the landslide and the analysis of the final accumulation shape of the landslide, and the impact of the landslide on the structures below the landslide The analysis of parameters such as force and displacement response of structures is rarely carried out.
