扬州市仪扬河大桥主桥总体设计

Overall Design of Main Bridge of Yiyang River Bridge in Yangzhou City

摘要:

城市跨河桥梁场地条件复杂、控制因素多、要求高，桥梁方案设计需要结合现场条件综合考虑多方面因素后才能确定。依托扬州市仪扬河大桥建设项目，对可行的主桥桥梁方案进行了充分比选，最终确定采纳所推荐的结构新颖、景观效果好的双层通行的矮塔斜拉桥设计方案。此外，对推荐方案的主桥总体设计进行了介绍，包括总体布置、结构设计、计算分析等内容，以期对同类桥梁的总体设计有所帮助。

Abstract:

The site conditions of urban cross-river bridges are complex with multiple control factors and high requirements. The design of the bridge scheme needs to be determined by considering various factors in combination with the site conditions. Relying on the construction project of the Yiyang River Bridge in Yangzhou City, the feasible schemes of the main bridge are fully compared. Finally, the design scheme for a double-deck low-pylon cable-stayed bridge with novel structure and good landscape effect is recommended and adopted. In addition, the overall design of the main bridge in the recommended scheme is introduced, including overall layout, structural design, calculation and analysis in order to provide the assistance for the overall design of similar bridges.
