【摘要】 本文对浅埋于可液化南京细砂地基中的地铁车站结构的大型振动台试验结果进行了进一步的整理,主要分析了地铁车站结构侧向地基土发生液化大变形时车站结构的应变反应、加速度反应和土与结构侧墙之间接触面的动土压力反应,结果表明:地铁车站结构侧向土体发生液化大变形时,地基土的大变形造成地铁车站结构中柱和侧墙都发生较大的不可恢复的残余变形;在侧墙底部记录的动土压力反应幅值明显比中部和顶部处记录的值要大,中板处的峰值加速度都比底板处的对应值要大。更多还原

【Abstract】 A large-scale shaking table test for subway station structure built on the liquefied saturate sand soil is implemented.The earthquake response and the dynamic soil pressure on the interface between soil and subway station structure are mainly analyzed.From the testing results,it is obvious that the large residual strain developed because of the large strain of liquefied soil beside the subway station.The dynamic soil pressure on the bottom of the side wall is obviously larger than that on the top of the side wall.The peak acceleration of the middle plate is obviously larger than that of the bottom plate.At the same time,some other valuable conclusions are put forward.更多还原
