摘　　要：文章以广西壮族自治区贵港市某跨江大桥总体方案为例,基于道路功能定位,结合规划条件、防洪堤交叉方式、通航净空及慢行交通过江方式,确定跨江大桥及连接线的路线和纵断面设计方案。重点探讨该跨江大桥主桥桥梁结构选型,提出335 m主跨中央索面斜拉桥、悬索桥、双索面斜拉桥,及钢箱提篮拱桥等桥型方案。结合“一桥一景”,经综合比较后确定中央索面斜拉桥为主桥推荐桥型,可为类似工程提供参考。Taking the overall scheme of a river-crossing bridge in Guigang,Guangxi Zhuang Autonomous Region as an example,this paper determines the route and profile design scheme of the river-crossing bridge and the connecting line based on the road function positioning,combined with the planning conditions,the crossing mode of the flood dike,the navigation clearance and the river crossing mode of slow traffic.It focuses on the structural selection of the main bridge of the river crossing bridge,and puts forward the bridge type schemes of 335 m main span central cable plane cable-stayed bridge,suspension bridge,double cable plane cable-stayed bridge,and steel box basket arch bridge.Combined with one bridge&one landscape,the central cable plane cablestayed bridge is determined as the recommended bridge type of the main bridge after comprehensive comparison,which can provide reference for similar projects.
