Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing:

[0027] Such as Figure 1 to Figure 9 As shown, the model test device for simulating earthquake occurrence and propagating soil-bond interaction in the present invention is realized by using a soft connection test model box combined with a multi-array shaking table system, and the earthquake propagation medium and model similarity law are considered in the test. The soft connection test model box is a soil and structural container, which is composed of two parts: a rigid part and a flexible part. Such as figure 1 , figure 2 As shown, the rigid part is a box made of rigid material, and the opposite surfaces of adjacent rigid parts are open. Such as image 3 As shown, the flexible part is composed of a universal joint pair device 3, a U-shaped steel skeleton and a rubber membrane. The structure of the universal joint pair device is as follows image 3 As shown, it inclu...

Abstract

The invention relates to a test device for simulating soil-structure interaction during earthquake occurrence and spread in the research of earthquake engineering. The device consists of a rigid part and a flexible part, wherein the flexible part consists of a universal joint pair device, a U-shaped steel framework and a rubber film; one end of a steel connecting rod with a slipway is fixedly connected with the upper end of a universal joint upper member, while the other end is connected with another universal joint upper member through a roller; the U-shaped steel framework is connected with the steel connecting rod with the slipway through a slideable connecting member; and the rubber film is arranged in a U-shaped space formed by the U-shaped steel framework and the universal pair device and is rigidly and segmentally connected with a model casing. Earthquake occurrence is simulated by combining a plurality of array vibrating table systems and applying different excitations to two adjacent vibrating tables simulating faulting. Corresponding excitations with different speeds are applied to other vibrating tables according to a similar rule so as to further research the interaction between soil and structural power with the consideration of the spread of earthquake in a medium.

Description

technical field [0001] The invention relates to a test device for simulating earthquake occurrence and propagating soil-structure dynamic interaction, which belongs to the field of earthquake engineering research. Background technique [0002] As we all know, earthquakes are mostly caused by the dislocation of faults. Shaking table model test is an important method to study the dynamic interaction between soil and structure, and plays an important role in the field of geotechnical earthquake engineering. Using model tests to truly simulate the dynamic interaction between soil and structures in earthquake occurrence and propagation is a research direction in the field of earthquake engineering. Among them, how to simulate fault dislocation is a difficult research problem. Designing a corresponding test model box device is an important part of its realization by using a multi-array shaking table test system. At present, the corresponding test model box device has not been rep...
