沪陕国家高速公路京杭运河斜拉桥主桥设计

Design of the Grand Canal Cable-stayed Bridge of Hushan National Expreesway

文章介绍沪陕国家高速公路京杭运河斜拉桥主桥的结构设计概况和特点,重点介绍了桥梁的总体布置,主塔、主梁、拉索的结构设计,并对结构进行了静力分析、局部应力分析和动力分析,结果表明,主桥成桥状态及最大悬臂施工状态抗震性能和抗风稳定性均满足规范要求。

The paper introduce the project design overview and the characteristics of the Crand Canal cable-stayed bridge of Hushan national expressway, the general plan, the structure design of main tower, main girder and cable are introduced emphatically, the static analysis, dynamic analysis and local analysis for bridge structure are also conducted. The results show that the seismic and wind resistance performance of main bridge in completion station and the largest cantilever construction state can meet the specification requirements.
