土-结构动力相互作用的振动台试验研究综述

Review of Research on Shaking Table Test of Dynamic Soil-Structure Interaction

本文从土-结构动力相互作用振动台试验过程中所涉及的结构模型动力相似设计、模型土体的模拟及土体边界条件的模拟三个方面,回顾了近几年来土-结构动力相互作用振动台试验研究的发展历程与现状,重点描述了试验过程中为了更好地反映震动条件下土与结构动力相互作用的机理,学者们所采取的办法和措施。并在此基础上,介绍了一种新的研究土-结构动力相互作用的振动台试验技术。最后,总结了传统的土箱-振动台试验存在的不足,并与这种新的试验技术进行了对比,提出了对于这种新的试验方法仍需要进一步研究和解决的问题。

This paper presents a review of shaking table test related to dynamic soil-structure interaction in three aspects： i.e.scale modeling method,simulation of soil,and simulation of soil boundary conditions.The active and effective measures adopted by researchers for better reflecting the interaction mechanism between soil and structure under shaking are described emphatically.Moreover,the disadvantages of the traditional test way by means of model box and shaking table are summarized.Finally,a new test technology in shaking table test of soil-structure interaction research is introduced and contrasted with the traditional test way.Some problems about this new test method need to be solved and investigated further are put forward in the end.
