Example Embodiment

[0022] In order to facilitate the understanding of the present invention, the present invention will be described in detail below with reference to the drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0023] Unless otherwise defined, all professional terms used hereinafter have the same meaning as commonly understood by those skilled in the art. The terminology used herein is only for the purpose of describing specific embodiments, and is not intended to limit the protection scope of the present invention.

[0024] In terms of tunnel deformation research, shaking table model test is mainly to reproduce the characteristics of tunnel dynamic response under seismic load and to better study tunnel failure mechanism. The prototype site tunnel is a free field in a semi-infinite space, and the boundary effect of the model box restricts the relative movement of the tunnel and s...

Abstract

The invention discloses a boundary layer of a vibrating table test model box. The boundary layer comprises a sponge rubber plate arranged on the inner wall of the model box and a foam plate arranged on the inner side of the sponge rubber plate, the sponge rubber plate is composed of an end wall sponge rubber plate body arranged on the end wall of the model box and a side wall sponge rubber plate body arranged on the side wall of the model box, and the foam plate is composed of an end wall foam plate body and a side wall foam plate body. Relative displacement based on a site is a main reason for damage of an underground structure; when a vibration table model test is carried out, a composite material boundary layer composed of different materials is arranged on the boundary of the model box, the whole model can be allowed to generate a certain displacement, the boundary effect of seismic waves on the model can be reduced, and then the reliability of a vibration table model test result is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, in particular to a model box boundary layer used for a shaking table model test. Background technique [0002] Shaking table test is one of the important methods for studying the seismic response of underground engineering structures. In addition to the structure itself, the object to be simulated during the test also needs to simulate the surrounding stratum of the structure. Device - model box. The shaking table test is an equivalent way to place the test object—structure and formation model—in the model box. [0003] In recent years, scholars from various countries have continued to carry out shaking table model tests. How to effectively simulate the model failure characteristics under seismic loads is a challenging topic. Scholars from various countries have carried out research on the boundary layer of the model box. But the effect of the shaking table test carried out is ...
