摘要
受两岸建设场地限制和乌江银盘电站蓄水影响,重庆武隆龙溪乌江大桥选用了“斜拉扣挂、挂篮悬浇”的钢筋砼箱型拱桥方案。文章重点介绍了大桥的主拱结构设计、主拱圈悬臂浇筑施工方案及工艺技术流程,可为受建设场地制约的大跨度砼拱桥的建设实践提供参考和借鉴。
Due to the limitations of construction sites on both sides of the Taiwan Strait and the impact of water storage at the Wujiang Yinpan Hydropower Station,the Wulong Longxi Wujiang Bridge in Chongqing has adopted a reinforced concrete box arch bridge scheme of"cable-stayed buckle hanging and hanging basket suspension casting".The article focuses on the design of the main arch structure of the bridge,the cantilever pouring construction plan of the main arch ring,and the technical process,which can provide reference and reference for the construction practice of large-span concrete arch bridges constrained by the construction site.
