Model test device for simulating stability of immersed roadbed

Abstract

The invention discloses a model test device for simulating the stability of an immersed roadbed, which comprises a roadbed system, a water channel and a water circulation system, and is characterized in that the roadbed system is provided with a roadbed system model box and a roadbed system model box used as a roadbed slope of the immersed roadbed and used for stacking the roadbed slope; the upper part of the cross section of the roadbed slope is trapezoidal, so that two tested slopes are formed on the left side and the right side of the roadbed slope; the water channel and water circulation system is provided with a left circulation water channel system and a right circulation water channel system, and the left circulation water channel system and the right circulation water channel system are arranged on the two sides of a roadbed slope in a clamped mode. The left circulating water channel system and the right circulating water channel system are provided with flowing water, and all or part of the two tested slopes are clamped and immersed in the flowing water of the left circulating water channel system and the right circulating water channel system. The device can be soaked in water from two sides, the change of the water level is adjusted, and the test device for simulating the water flow can improve the related research in the field and provides scientific reference and support for further solving the problems.

Description

technical field [0001] The invention relates to a test device, specifically a model test device for simulating the stability of a submerged roadbed. Background technique [0002] The current social development is rapid, and road construction continues to advance. Many roads are built along rivers, thus forming flooded roadbeds. In addition to the traffic load, the flooded subgrade is also affected by the rise and fall of groundwater, seepage and river erosion, which affects the settlement and deformation of the subgrade and affects the long-term stability of the subgrade slope. [0003] At present, the main methods for studying the stability of submerged subgrades include theoretical analysis, numerical simulation, field monitoring and indoor model tests. Theoretical analysis and numerical simulation often need to simplify the parameters and establish an ideal model, which makes it more different from the actual situation; on-site monitoring needs to embed monitoring equipm...

AI Technical Summary

Problems solved by technology

The structure of the device is relatively simple. The slope of the subgrade is one-sided, and the water level rises and falls on one side. The water cannot flow, which is inconsistent with the actual situation of the subgrade near the water.
