Introduction Greeting the coming of the 21st century, Professor HU Yu-xian and other Chinese scholars briefed the trend of earthquake engineering in China and aboard (HU, 1999; HU, ZHOU, 1999). The experiences and lessons learning from the destructive earthquakes in China and abroad in re-cent years, the damage action of the large velocity impulse in ground motion in near field in seis-mic design, numerous earthquake examples show that there are many weaknesses in aspects of earthquake p… 相似文献

神户大开地铁车站的地震反应分析 总被引:24,自引:3,他引:24
本文对阪神地震中大开地铁车站的地震破坏机理进行了分析,复反应分析方法的计算结果表明大开车站的中柱在水平和竖向地震动作用下产生的较大内力,导致了整个地下结构的破坏;计算结果还表明在阪神地震中,竖向地震动作用下地下结构所产生的内力比水平地震动作用下产生的内力要大。 相似文献

Dynamic contact theory is applied to simulate the sliding of surface fault.Finite element method is used to analyze the effect of surface fault to site ground motions.Calculated results indicate that amplification effect is obvious in the area near surface fault,especially on the site that is in the downside fault.The results show that the effect of surface fault should be considered when important structure is constructed in the site with surface fault. 相似文献
