Abstract
In this paper, according to a particular ground fissures in Xi’an city in the south of the actual stratigraphic profiles use a similar role of strong earthquakes and the theory of vibration table crack mechanical response model test for similar relation design. Find out the model of soil physical and mechanical parameters. And then, design the model soil box and the loading system. Finally, through the finite element software testing model, a numerical simulation, verify the vibration table model test the feasibility of the scheme. And we got strong earthquakes and the role of crack, acceleration, speed, displacement and shear stress response law of dynamic characteristics, etc. Do preparations for studying strong earthquakes and role of the dynamic response of crack shaking table model test. This paper sets the vibration model test design, and the finite element calculation results for the next step and strong earthquakes role of the dynamic response of crack shaking table model test study to lay the foundation. The method and the conclusion of the test, for future trials and Fen Wei basin with similar to crack period of linear across the seismic design of engineering structures provide certain theoretical support and reference value.
