结合工程实例探讨钢管混凝土拱桥施工技术结合工程实例探讨钢管混凝土拱桥施工技术 摘要:钢管混凝土拱桥是我国近年来桥梁建设进展的新技术,具有自重轻、强度大、抗变形能力强的优点,是大跨度拱桥的一种比较理想的结构形式
随着跨径的增大,钢管本身的架设难度也越来越大
本文结合武汉轨道交通工程一号线工程实例,对跨江岸货场槽形梁拱组合桥钢管拱施工技术进行了探讨
关键词:武汉某工程;钢管拱施工;技术要点 Abstract: The CFST arch bridge is a new bridge building technology development in China in recent years has the advantages of light weight, high strength, strong resistance to deformation, it is an ideal structural form of large span arch bridge
With the span increasing, the erection of steel pipe is more and more difficult
This combination of Wuhan rail transit project line 1 example, arch construction techniques discussed arch bridge of steel tube to cross the river yard trough girder
Key words: an engineering in Wuhan; steel tube arch construction; key technology 中图分类号:U415
