摘　　要：上海军工路高架桥连接逸仙路高架与中环线高架,全长约7.3 km。其设计中,提出了“小型化、轻型化、快速化、工业化”的建设理念,在桥梁上部结构大规模采用钢-混凝土组合梁,分开预制钢-混凝土组合梁或整体预制钢-混凝土组合梁二种结构体系,并首次将重型H型钢应用于组合梁中。The Shanghai Jungong Road viaduct connects the Yixian Road viaduct and the Middle Ring Road viaduct,with a total length of about 7.3 km.Adhering to a construction philosophy of"miniaturization,light weight,rapidity,and industrialization",the upper structure of the bridge uses steel-concrete composite beams as the basic structural form,utilizing two main structural systems:separately prefabricated steel-concrete composite beams or integrally prefabricated steel-concrete composite beams.Heavy H-shaped steel was first applied to composite beams.
