摘要

为剖析地震时地铁车站的动态响应及破坏机理,以1995年日本阪神—淡路大地震中遭受严重破坏的神户大开地铁车站为对象,进行了一系列的模型振动试验。为分析地下结构的地震时响应和箱型地铁中柱的减震效果,对地震波输入方向对减震效果的影响进行了深入细致的研究,得到了一些有益的结论,为今后的抗震减震工作提供了科学的依据。
In order to clarify the dynamic behaviors and the damage mechanism of the subway structure,a series of shaking table tests of Dakai subway station damaged in 1995 Hyogoken-nanbu earthquake are performed.To analyze the dynamic behavior of the subway structure and the effects of the shock absorption at the center column,the effects of the directions of waves on anti-earthquake are investigated.Some useful conclusions are given,which can improve the anti-earthquake designing level of underground structures.
