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.
