摘要
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。
The damage mechanism of the Dakai subway station in Hyogoken nanbu earthquake is analyzed in this paper. Complex response is used to calculate earthquake response of the underground structure. The analyzed result shows that the larger shear forces and axial forces, which were caused by horizontal and vertical ground motion, resulted in damage of the whole structure station. The calculated result also shows that the response of mid column of the Dakai subway station, which was resulted from the vertical ground motion, was larger than that resulted from the horizontal ground motion.
