摘要 介绍了波形钢腹板在桥梁结构中的应用发展概况和国外大跨度混凝土拱桥最新的研究进展,提出了波形钢腹板混凝土拱桥新型桥梁结构,并以重庆万州长江大桥为原型进行了试设计,对试设计初步成果进行了介绍。分析结果表明,这种新桥型在减轻拱圈自重、方便施工、缩短工期等方面具有相当的优越性,为混凝土拱桥向大跨径发展提供了一个新的思路。 This paper gives a summarized account of the application and development of corrugated steel webs used for bridge structures,the latest research advancement of long span concrete arch bridges abroad and proposes a new type of concrete arch bridge structure composited with corrugated steel webs. By taking Wanzhou Changjiang River Bridge in Chongqing as the prototype, the trail design of the proposed new type of the arch bridge is carried out and preliminary achievements of the trial design are presented. The results of the design and analysis show that the new type of the bridge structure has considerable advantages in aspect of decreasing dead weight of main arch ring, making construction easier and shortening construction time schedule, and the type of the bridge provides a new alternative for the development of concrete arch bridges towards still longer spans.
