摘要
西江特大桥是广佛江珠城际铁路的重要桥梁,为取得主桥合理的桥式方案,遵循"安全、实用、经济、美观"的设计原则,按照单向通航和双向通航的净空要求,采用钢桁拱桥、钢桁斜拉桥及矮塔斜拉桥,对4种桥型设计方案进行对比分析计算,综合考虑施工难度、景观效果、通航条件及工程造价等因素,最终得出双孔252 m钢桁拱桥为推荐方案。
The extra-long bridge across Xijiang river is an important bridge on Guangzhou-Foshan-Jiangmen-Zhuhai intercity railway. In order to determine the most suitable bridge type,this article compares and analyzes 4 bridge schemes,including steel truss arch bridge,steel truss cable-stayed bridge and low tower cable-stayed bridge following the design requirements for safety,functionality,cost-effectiveness and aesthetics based on clearance requirements for one-way and two-way navigation.Finally,the scheme of double 252 m steel truss arch bridge is recommended in view of construction difficulty,landscape effect,navigation condition,engineering cost and other factors.
