摘　　要：交通综合体是重要的城市基础设施。针对兰州中川机场T3航站楼+GTC(综合交通中心)+国铁/地铁“哑铃型”结构布置特点,建立包含国铁车站和区间隧道、地铁车站和区间隧道、T3航站楼、GTC的空间三维结构化有限元模型,输入场地人工地震波,研究模型在7度设防地震下结构的动力响应时程。围绕结构抗震性能、国铁/地铁区间结构与车站主体结构的连接设计及抗震构造等进行评价,以实现其设计优化、性能提升、施工便捷,从而为兰州中川机场T3、GTC、国铁/地铁组合的结构设计提供设计建议和理论支撑。Transportation hub is one of the key urban infrastructures.Targeting the structure layout feature of’dumbbell’of Lanzhou Zhongchuan Airport Terminal 3+GTC(global transportation center)+national railway/metro,a 3 D structural finite element model that includes national railway station and interval tunnel,metro station and interval tunnel,T3 building,GTC is established.Site artificial seismic wave is input to study the structure dynamic response time history under 7-degree earthquake fortification design in the model.Evaluation is carried out on structure aseismic performance,connection between national railway/metro interval structure and station main-body structure and aseismic design.Design optimization,performance improvement and construction convenience are achieved,providing suggestion and theoretical support for Lanzhou Zhongchuan Airport T3,GTC,national railway/metro combination structure design.
