Side cover plate for geotechnical engineering physical model test

Abstract

The invention relates to a side cover plate for a geotechnical engineering physical model test, comprising a main cover plate framework, an organic glass plate, a supporting frame and a stiffening rib, wherein the organic glass plate and the supporting frame are both installed on the main cover plate framework; the inner side of the supporting frame is in contact with the outer side of the organic glass plate; one end of the stiffening rib is rotatably connected to the main cover plate framework; the stiffening rib is adhered to the outer side of the organic glass plate; and the organic glass plate is provided with an excavation hole. The side cover plate for the geotechnical engineering physical model test can be repeatedly utilized, the organic glass plate facilitates digital photographing, and the information, such as soil mass deformation and the like around a cavern is directly collected.

Description

technical field [0001] The invention relates to a side cover plate for a geotechnical engineering physical model test, in particular to a reusable side cover plate for a geotechnical engineering physical model test. Background technique [0002] In the field of geotechnical engineering, the methods commonly used to investigate the actual engineering conditions are mainly prototype observation, numerical method and model test. Prototype observation is the most direct and convincing method to study the properties of structures, but the prototype test steps are complicated and expensive, and it is only used in a small number of engineering practices. The numerical method is a method of abstracting the numerical model from the actual research object, which is less expensive and convenient, but the accuracy of the numerical model mainly depends on the accuracy of the input parameters and the constitutive relationship, and the input parameters and the constitutive relationship obt...

Problems solved by technology

[0005] (1) The stiffeners in the middle of the excavation hole cover will affect the excavation of subsequent tunnels and caverns;

[0006] (2) When carrying out tests under different working conditions, due to the differences in the excavation size, number, depth and relative position of the caverns under different working conditions, it is necessary to replace the cover plate of the excavation hole as a whole, which requires a large amount of work and high production costs
