摘　　要：青洲闽江大桥正桥为主跨 60 5m的结合梁斜拉桥 ,桥面宽 2 9m ,通航净高 4 3m ,该桥两主墩基础分别采用直径 2m钢管桩和直径 3m的钻孔桩 ,钻石形主塔 ,主梁采用工字形钢纵梁和混凝土面板共同受力的结合梁 ,主梁上的斜拉索锚固结构直接焊接于主梁的上翼板 ,斜拉索采用新型钢绞线体系。介绍该桥结构设计特点以及结构的架设与安装程序 。The main bridge of Qingzhou Minjiang Bridge is a composite girder cable stayed bridge with main span of 605 m. This bridge has the longest span of composite cable stayed bridge in the world and its deck width is 29 m, navigation clearance is 43 m. Foundation of two diamond\|shaped main towers are steel pipe piles with diameter 2 m and bored piles with diameter 3 m respectively. The composite girder consists of 2 steel I section longitudinal beams and concrete deck slab. Cable anchorage structures are welded on the top flange of longitudinal girders. New type strands are used for all cables. Distinguished anti wind behavior and aerodynamic measurement of this bridge are also presented in this article.
