摘　　要：近年来,无风撑空间网状吊杆拱桥在国内的应用方兴未艾,对其研究和成熟工程案例鲜有介绍。文章从二十涌大桥无风撑空间网状吊杆主桥吊杆的布置、主拱及箱梁的结构等方面进行精心设计,对其结构进行了深入的分析,提供了一座无风撑空间网状吊杆拱桥的工程案例。结合桥位所处的环境采用顶推施工方法,很好地满足了施工工期的要求。In recent years,the application of the spatial network arch bridge without wind bracing is in the ascendant in China,and its research and mature engineering cases are rarely introduced.This paper designs the layout of the arch boom,the structure of the main arch and box girder,and other aspects of Ershiyong spatial network arch bridge without wind bracing,conducts in-depth calculation on its structure,and provides an engineering case of spatial network arch bridge without wind bracing.Combined with the environment of the bridge,the jacking construction method is adopted,which well meets the requirements of the construction period.
