摘　　要：深圳市黄木岗交通枢纽立交桥为国内首座站桥合建的下承式大跨度钢拱桥。为了解决枢纽地下车站与拱桥合建问题,对大跨度桥梁与地下结构合建的节点体系构造进行了研究,并采用数值模拟方法分析了站桥合一结构的静力特点和动力特性;同时对桥梁结构的抗风性能、桥梁结构形式及受力特点进行了分析。该桥的设计研究对于站桥合建的桥梁建设提供了新的思路,可供相关人员参考。The overpass at Huangmugang Transportation Junction in Shenzhen City is the first long-span through steel arch bridge of the co-constructed bridge and station in China.In order to solve the problem in the co-construction of underground station and arch bridge in the junction,the joint system structure of the co-constructed long-span bridge and underground structure is studied,and the static force characteristics and dynamic properties of the co-constructed structure of station and bridge are analyzed by the numerical simulation.At the same time,the wind resistance performance,structural form and stress characteristics of bridge structure are analyzed.The design study of the bridge provides a new idea for the co-construction of the station and bridge,which can be used as reference for relevant personnel.
