摘要
钢桁架桥因具有建筑高度低、跨越能力强、结构刚度大等优势而被广泛应用于现代桥梁建设中,文章结合跨京杭运河大桥主跨138.5m的钢桁架,从总体选型、结构设计、静力分析、施工方案等方面介绍了该大跨径变高度简支钢桁架梁的设计思路,旨在为今后类似桥梁的设计提供借鉴和参考。
Steel truss bridge is widely used in modern bridge construction due to its low building height,long-span capacity and largely structural stiffness.This paper introduces the design idea based on the main span of 138.5 m steel bridge over Jing-Hang Canal from the aspects of overall design,structural design,calculation analysis and construction plan,aiming to provide reference for the design of such bridges in the future.
