| 摘 要： | 地下结构的关键构件(如柱子等)在地震作用下可能发生破坏,进而影响结构体系的整体稳定性。在借鉴传统反应位移法的基础上,提出了一种新的位移时程反应分析方法,采用该方法对日本神户大开地铁车站进行地震响应分析。结果表明:位移时程反应分析方法能够考虑土-结构相互作用、材料非线性、几何非线性、水平地震与竖向地震的耦合作用及地震动传播的时空效应,适用于地下结构地震反应分析,利用该方法得出的地铁车站结构变形及损伤破坏与实际震害观察具有较好的一致性,并指出大开地铁车站结构的整体垮塌是由于柱子剪坏和高轴压联合作用所致。

| Abstract: | Under the action of earthquakes, some key components of underground structures may be damaged, and the stability of the whole structure may deteriorate. Based on the traditional response displacement method, a new response analysis method of displacement time-history is proposed, and the characteristics and solution procedure of the method are introduced. Seismic response analysis of the Daikai subway station in Kobe, Japan, was conducted using the proposed method, which takes several aspects, e.g., the soil-structure interaction, material nonlinearity, geometry nonlinearity, coupling effect of horizontal shock and vertical shock, and the time-space effect of ground motion propagation, into consideration simultaneously. As the deformation and damage failure of the metro station obtained by the proposed method agreed well with actual results, the method is suitable for seismic analysis of underground structures. |
