摘　　要：福建省漳州开发区双鱼岛大桥主桥为36 m+2×66 m+36 m独塔双索面斜拉桥,主梁采用鱼腹式预应力混凝土连续箱梁,索塔为双鱼门型钢塔,桥墩为椭圆造型,采用钻孔灌注桩基础。介绍该桥各主要结构的设计,通过建立有限元整体计算模型及局部计算模型对该桥主梁、索塔、斜拉索、钢锚箱的受力进行分析并对其施工方案进行介绍。Main bridge of Shuangyudao Bridge in Fujian Zhangzhou Development Zone is a 36m ＋2×66m ＋36m cable-stayed bridge with single pylon and double cable planes, and its girders are fish-belly prestressed concrete continuous box girders, cable pylon is twin-dolphin gate-typed steel tower, piers are in elliptic shape and bored pile foundation is adopted. This paper introduces design of all major structures, analyzes stresses on girder, cable pylon, stayed cable and steel anchor box of the bridge by establishing finite-element integral and local computational models and introduces its construction scheme.
