摘　　要：泰州大桥是世界上首座超千米的三塔两跨悬索桥,加劲梁结构体系复杂并有其独特之处。在设计过程中根据三塔悬索桥的结构特点,加劲梁构造细节设计在润扬大桥的基础上做了较大改进和创新,介绍了加劲梁的结构体系、构造设计、结构计算以及梁段的加工制造和架设情况。Taizhou Bridge is the first three-tower two-span suspension bridge with the main span over 1 000 m in the world. The structural system of the stiffening girder is complicated and unique. Improvement and innovation have been made in detailed structure design of the stiffening girder based on Runyang Bridge according to the structural character of three-pylon two-span suspension bridge. In this paper, the structural system, structure design, structure calculation, manufacturing and erection of the stiffening girder are introduced.
