摘　　要：蒿枝港桥位于临海高等级公路启东北段,主桥跨越蒿枝港Ⅲ级航道,主桥上部结构采用(51+85+51)m变截面悬浇预应力混凝土连续箱梁。介绍了该桥主桥的设计概况、径向力控制、钢束布置、箱梁横向计算及合拢段设计等几个关键问题。Haozhi Harbor Bridge is located at the north section of Qidong of coastal high - grade highway, with the main bridge across the III - grade channel of Haozhi Harbor. The （51 ＋ 85 ＋ 51 ） m variable cross - section suspended casting prestressed concrete continuous box beams are adopted for the upper structure of the main bridge. Some key issues are introduced including the design, radial force control, restrained steel column arrangement, transversal calculation of box beams and closer section design of the main bridge, etc.
