摘　　要：泉州金鲤大桥长约1.61 km,连接晋江两岸,由南引桥、主桥、北引桥及匝道组成。主桥立意于泉州古城区鲤鱼轮廓造型,采用180 m跨网状吊杆系杆拱桥,桥面宽43.5 m;主梁采用钢-混组合梁,钢梁为双主梁纵横梁格体系;拱肋为变截面八边形钢箱提篮拱,横桥向2片拱肋采用横撑和斜撑连接;吊杆采用环氧涂层钢绞线成品索、销接式叉耳锚固。引桥及匝道主要采用预应力混凝土现浇大箱梁,主梁分幅布置,其中跨江引桥及匝道为基本跨径40 m等高梁,两幅桥之间的翼缘挑臂下敷设110 kV高压电缆随桥过江;跨江滨路引桥为主跨50 m变高连续梁;陆上引桥为基本跨径30 m等高梁,北侧陆上小半径曲线段引桥采用墩梁固结钢箱连续梁。通过采用钢-混组合梁网状吊杆系杆拱桥、分幅布置引桥及精细化设计,获得了良好的景观效果和经济性,在市政桥梁中实现了高压电缆随桥过江。The Jinli Bridge in Quanzhou crossing Jinjiang River consists of a south approach,a main bridge,and a north approach bridge,with a total length of about 1.61 km.To echo the cultural element—carp of Quanzhou(the outline of the ancient city of Quanzhou appears to be a carp),the bridge is designed as a network tied arch bridge spanning 180 m,with a deck width of 43.5 m.The deck system consists of latticed steel girders and concrete deck panels.The arch is a steel basket-handle arch of octagonal cross-section that tapers from the arch springing to the arch crown,the two arch rings are linked by horizontal bracings and the in-between M-shaped diagonal bracings.The hangers,consisting of epoxy-coated steel strands,are anchored via fork pins to the arch and the deck.The approaches and ramps have dual superstructures consisting of cast-in-situ prestressed concrete box girders,among which the portion of the river-crossing approaches and ramps comprise 40 m-long typical spans of constant-depth girders,and the 110 kV high-voltage cables are carried under the flanges of the box girders in the dual superstructures.The river-crossing Binbei Road approach is a haunched continuous girder bridge with a main span of 50 m.The land approaches consist of 30 m-long typical spans of constant-depth girders.The sharp-radius curved portion of north land approach is a continuous steel box girder structure in which the piers and the superstructure are fixed.The configuration of the Jinli bridge achieves great landscaping and economic effects,and allows the high-voltage cables to be carried over the river as well.
