Abstract

The invention relates to a model box rotary joint device used for tunnel structure multi-point vibration table test. The joint device is connected with two model boxes; the joint device comprises a rotating shaft toggling bolt, a toggling slot, springs, end portion U-steel, cover plates and an impermeable material; the rotating shaft toggling bolt is arranged at an edge of the bottom of one of the two model boxes; the toggling slot is arranged at an edge of the bottom of the other model box; edges of adjacent bottoms of the model boxes are respectively provided with end portion U-steel; the end portion U-steel is provided with the cover plates; the rotating shaft toggling bolt is inserted into the toggling slot, such that a connecting component can be formed; two sides of the connecting component are symmetrically provided with springs for connecting the two model boxes; the impermeable material is arranged between the two model boxes and is used for preventing model soil arranged inside the two model boxes from being exposed. Compared with the prior art, the model box rotary joint device of the invention has the advantages of sufficient strength, elastic rotation capacity, high axial stiffness, high shear stiffness, sealing function and the like.

Description

technical field [0001] The invention relates to a connection joint, in particular to a model box rotary joint device used for multi-point shaking table tests of tunnel structures. Background technique [0002] With the occurrence of earthquake damage to underground structures, the research on seismic resistance of underground structures has received extensive attention. Shaking table model test is an important method for seismic analysis of underground structures, which has been widely used and recognized. An important difference between the seismic response of underground structures and aboveground structures is that the underground structure is located in the rock-soil medium. Under the action of an earthquake, the structure and the rock-soil medium interact to show different vibration characteristics. By placing model geotechnical materials and underground structure models in the model box, the interaction between underground structures and geotechnical media can be simu...
