扬州江广快速路连续钢桁架拱桥设计及计算

Design and Calculation of Continuous Steel Truss Arch Bridge in Jiangguang Expressway of Yangzhou

结合扬州江广快速路茱萸湾大桥工程实例,系统介绍了工程概况、主要技术标准、总体布置、结构设计、结构计算,详细论证了连续钢桁架拱桥的主桁架、桥面系、组合桥面板、吊杆和系杆设计关键技术,对结构整体静力、动力、稳定、组合桥面板进行了深入计算分析,为类似桥梁工程建设提供参考。

Combined with the engineering case of Zhuyuwan Bridge in Jiangguang Expressway of Yangzhou, the engineering situation, the main technical standards, the overall layout, the structural design and the structure calculation are systematically introduced. The key design technologies of main truss,deck system, composite deck, suspender and tie bar of the continuous steel truss arch bridge are demonstrated in detail. The static, dynamic and stability of the whole structure and the composite deck are deeply calculated and analyzed, which can provide the reference for the construction of the similar bridge projects.
