Embodiment Construction

[0027] Such as figure 1 , figure 2 , image 3 , Figure 4 Shown, a kind of assembly type variable rigidity model box that is used for shaking table test, described model box is spliced ​​by wall body, bottom plate 6 and side column 4, and described wall body is made of several beams 1, some columns 2, The bottom beam 3 and the enclosure plate 5 are flexibly connected and formed by fasteners; the side wall of the model box is formed by flexible connection of multiple walls through the side column 4, and the side wall of the model box is hinged and fixed on the bottom plate 6 to form the model box. The bottom plate 6 is rigidly connected to an external vibrating table 8 .

[0028] The wall is formed by flexible connection of several crossbeams 1, several upright columns 2, bottom crossbeams 3 and enclosure plates 5 via bolts 7.

[0029] Described crossbeam 1 quantity is the crossbeam quantity that makes the lateral rigidity of model box structure reach the required rigidity...

Abstract

The invention discloses an assembling type variable rigidity model case used for a vibrating table test. The model case is composed of walls, a bottom plate and side pillars through splicing. The walls are formed by flexible connection of multiple transverse beams, multiple pillars, bottom transverse beams and enclosing plates through fasteners. The side wall of the model case is formed by flexible connection of multiple walls through the side pillars. The side wall of the model case is fixed on the bottom plate so that the model case is enabled to be formed. The bottom plate is rigidly connected at an external vibrating table. Side rigidity of the model case can be flexibly adjusted in the vibrating table test requiring simulation of a hard soil or soft rock site so that the model case is enabled to be suitable for the vibrating table test of the hard soil or soft rock site.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to an assembled variable rigidity model box for shaking table tests. Background technique [0002] In the structural testing of underground buildings (such as subways, tunnels, etc.), the shaking table test plays an important role. In the shaking table test of underground structures, the structural model is usually placed in the model box together with the rock and soil model to simulate the seismic response of the structure in the actual site. Therefore, the structural form of the model box, especially whether its lateral stiffness characteristics are compatible with the dynamic characteristics of the simulated site, has a great influence on the rationality of the test results. [0003] At present, the commonly used shaking table test model box includes two categories: rigid box and layered shear box. In the design index of the model box, the lateral stiffness of the mo...
