摘　　要：文章以正在建设的常泰长江大桥和张靖皋长江大桥为例,对超大跨径斜拉桥和悬索桥的结构体系进行分析,讨论了超大跨径斜拉桥的塔梁约束、索塔锚固及沉井基础,超大跨径悬索桥的缆塔约束、索塔形式、锚碇基础及正交异性桥面板等结构体系设计的关键技术问题,给出了相应的解决方案,以期为我国其它超大跨径缆索承重桥梁的建设提供借鉴。Taking Changtai Yangtze River Bridge and Zhangjinggao Yangtze River Bridge under construction as examples,this paper analyzes the structural system of super long span cable-stayed bridge and suspension Bridge.Firstly,the key technical problems in structural system design,such as the restraint of pylon and girder,anchorage of SOTTA and caisson foundation of super long span cable-stayed bridge,the tower restraint,tower form,anchor foundation and orthotropic deck plate of super long span suspension bridge were researched.Then,new structure systems for super-long span bridges is proposed as a solution.It is expected to provide reference for the construction of other super-long span cable-supported bridges in China.
