摘要
万州长江大桥为三跨连续钢桁拱桥,其钢梁架设除采用了临时支墩和吊索塔架辅助悬臂架设外,还首次应用了架梁爬行吊机(起重量350kN、能在24°斜坡行走)。简要阐述连续钢桁拱桥钢梁架设方案及关键技术。
Wanzhou Changjiang River Bridge is a 3-span continuous steel truss arch bridge. During the cantilever erection of the steel girder of the Bridge, in addition to the temporary piers and cable bent towers used in aid of the erection, the crawler cranes with lifting capacity 350 kN each and able to climb a 24°slope were also used for the first time. In this paper, the erection schemes and key techniques for the steel girder are described.
