摘　　要：以天津站交通枢纽工程结构为例,分别取结构典型的横向及纵向剖面,应用大型通用有限元分析软件ANSYS,建立考虑土与结构相互作用的有限元模型,采用动力时程分析方法,研究体系在水平地震作用下的弹塑性动力反应规律,分析结构在地震动作用下的位移和内力的分布,验证了车站结构的抗震性能,并为在武器打击下交通枢纽的动力响应分析提供参考。With the development of the urban traffic,the orbital transportation developed rapidly and became an important part of the transportation.The transportation hub also has the function of urban air-defence engineering.Considering the soil-structure interaction,the finite element model of two typical cross sections of the Tianjin Transportation hub were established by using the ANSYS software.The elastic-plastic time history analysis was made,and the seismic responses of the whole system under the horizontal seismic load were obtained.The seismic performances of the Tianjin transportation hub were validated.And the analysis method offered some certain valuable references on the transport hub structure under weapon hit.
