摘要：常泰长江大桥是一座集成高速公路、城际铁路、普通公路三种交通运输方式的大跨度桥梁。三种交通功能在桥上采用相对独立的方式布置，最大限度地节约资源、保障安全、提升桥梁使用功能。为尽量减少桥梁建设对长江航运的影响，主航道桥采用主跨1176m的斜拉桥跨越长江主航道。主跨1176m的超大跨度斜拉桥建造充满技术挑战，设计中对斜拉桥结构体系、新型基袖型式、新型桥塔结构及索塔锚固结构、恒载横向不对称结构行为等开展了系统研究，提出了温度自适应体系、台阶型沉井基袖、空间钻石型桥塔、钢箱一核芯混凝土组合结构，较好地解决了超大跨度桥梁的建设难题。

Abstract：The Changtai Changjiang River Bridge is a long-span bridge that will fulfill multiple purpos of transportation by accommodating highway,intercity railway and urban road traffic after completion.The three types of traffic passages are parately arranged with intent to reduce the materials needed,ensure safety and improve the functionality of the bridge to the maximum.To elimina0e0heinfluenceofbridgecons0ruc0ionon0henaviga0ionof0heChangjiangRiver0oa minimum,the main navigational channel bridge is designed as a cable-stayed structure with a main span of1176m.Multiple technical challenges are faced by engineers to realize the construction of such agiqq帅气男生头像
