摘要
回顾历史上地铁地下结构的震害现象,尤其是日本阪神地震大开地铁站的震害.简要归纳目前地下结构抗震研究主要方法,包括静力法、BART法、反应位移法及动力有限元法等.总结地铁地下结构在一致地震动作用下的地震反应研究现状.对地铁地下结构在非一致地震动作用下的地震反应研究、非一致地震动自由波场输入方法及其人工边界研究进行简要描述.概述了地铁地下结构的振动台试验研究现状,包括普通振动台试验、离心机振动台试验和针对非一致激励的振动台试验.对地铁地下结构抗震领域提出进一步研究展望.
Firstly review the seismic damage phenomena of subway structures in history,especially focus on the seismic damage mechanism of Japanese Dakai station which heavy damaged during the great Hanshin earthquake.And than briefly summarize the major methods of seismic response analysis in recently,including static method,BART method,the method of response displacement,and dynamic finite element method,and so on.Summarize the numerical modeling research method status of subway structures under uniform seismic excitation,the research method status of subway structures considering the spatial variation of earthquake ground motion,and summarize the research status of input methods of non-uniform seismic wave and artificial boundary.And at last,briefly summarize the shaking table test research of subway structures,including the general shaking table test and the centrifuge shaking table test and the special shaking table test for non-uniform seismic excitation.In the end,give out some advice about further seismic research of subway structures.
