Structural System Design&Stress Analysis of Curved Girder Bridge with Special-Shaped Arch Ribs
Jingzhansha River Bridge is located in Tianmu Lake scenic spot,Liyang,Jiangsu,with a total length of 248 m and span arrangement of 80 m+123 m+45 m.The curved beams,shaped arches and fan-shaped space cable surface form a Guqin shape.The overall shape is simple and novel,breaking through the traditional arch bridge shape.This paper describes the main structure design of the bridge,combined with the finite element calculation model,the structure system is compared and selected,and the structure system with the separation of arch pier is finally determined.The empirical calculation shows that the structure safety meets the design requirements,which can provide reference for the design and construction of similar bridges.
