摘要
文章以宜万铁路宜昌长江大桥主桥设计、施工监控为工程背景,对钢管混凝土拱桥拱肋预拱度设置方法进行分析比较,总结出按二次抛物线法对钢管混凝土拱桥拱肋各节段预拱度设置,与设计值、实测值一致,基本满足设计要求,对拱肋施工控制有实际指导意义。
Wanzhou Railway Bridge of Yichang Changjiang River Bridge design, construction monitoring for the engineering background of concrete steel arch bridge camber setting methods were analyzed and compared, summed up by a parabolic law CFST Arch Bridge each segment camber settings, with the design value, Cece value consistent, basically meet the design requirements of the rib construction control has practical significance.
