摘　　要：系杆拱桥是欧洲常用的一种结构体系,因具有受力合理、用材经济、施工方便、造型优美等优点,近年来在我国得到广泛应用。四拱肋无风撑系杆拱桥造型更加丰富,景观效果极佳,但受力也较常规系杆拱桥更加复杂。以采用四拱肋无风撑系杆拱桥方案的珠海市斗门区幸福河拱桥为工程背景,建立有限元模型进行计算,对拱轴线、矢跨比、拱间连接形式、施工顺序等关键参数进行了分析比选,综合考虑结构受力及景观效果后,最终选定了该桥的合理设计方案。相关研究和设计成果可为今后同类桥型设计提供借鉴。The bowstring arch bridge is commonly used in Europe,and has become very popular in China because of its merits such as reasonable stress,economic material,convenient construction and beautiful design.The four-arch-rib no-wind-brace bowstring arch bridge has more abundant shape and excellent landscape effect,but its stress is more complicated than the normal bowstring arch bridge.Taking Xingfu River Arch Bridge in Doumen District of Zhuhai as the engineering background,the finite element model is built to calculate,analyze and select the key parameters such as arch axis,rise span ratio,arch connection and construction sequence.By comprehensively considering the structural stress and landscape effect,the reasonable design scheme of the bridge is selected.The relevant research and design results can provide reference for the design of the similar bridges in the future.
