Multifunctional three-dimensional model testing platform for roadbed slope and underground engineering

Abstract

The invention provides a multifunctional three-dimensional model testing platform for a roadbed slope and underground engineering. The multifunctional three-dimensional model testing platform is composed of an underground groove body, a ground reaction wall, a ground groove body, a servo actuator, a loading plate, a middle separation plate, an underground water system and an artificial rainfall system, wherein the ground reaction wall is located at one end of the underground groove body; the ground groove body is mounted on the side wall of the underground groove body; the servo actuator is arranged between the ground reaction wall and the ground groove body; the underground water system is arranged in the ground groove; the artificial rainfall system and a shower nozzle are arranged above the ground groove body. The construction of the multifunctional three-dimensional model testing platform for the roadbed slope and the underground engineering can further improve an existing large-size foundation and slope model testing system, so as to provide a good testing platform for a large-scale model test of engineering projects including roadbed slope supporting structures, foundation treatment, tunnels, foundation pits and the like; the construction cost is reduced and the model testing efficiency is improved.

Description

[0001] technical field [0002] The invention relates to a multifunctional three-dimensional model test platform for roadbed slope and underground engineering. Background technique [0003] Geological hazards of subgrade slopes generally include landslides, collapses, and debris flows. Roadbed and slope disasters often interrupt traffic, block rivers, bury villages and towns, destroy factories, and destroy farmland, causing huge losses to people's lives and property, and seriously affecting engineering construction. [0004] Large-scale physical model test is one of the effective means to study the occurrence law of landslides and other subgrade slope disasters, as well as the mechanical characteristics of retaining structures and support effects. It can effectively help solve landslides and other subgrade slope disasters and control engineering Theoretical and practical problems, can show the whole process of the development of landslides and other disasters that are d...

AI Technical Summary

Problems solved by technology

[0006] However, the above-mentioned model test system still has many deficiencies, mainly as follows: 1) There is no large-scale horizontal loading facility, so it is difficult to carry out model test research on subgrade slope retaining structures, foundations, tunnels, foundation pits, etc. ; 2) The model slots are all above the ground, so deformation control is difficult and the cost is high; 3) The see-through area of ​​the side wall is small, and it is difficult to observe the deformation of the model, etc.
