钢管混凝土拱桥线形控制技术研究

Study of Alignment Control for Concrete Filled Steel Tube Arch Bridge

结合钢管拱肋节段的悬拼,讨论了施工过程中几种线形之间的关系,为施工线形控制提供了依据,在此基础上提出了计算和控制吊装线形的方法。这种方法也可运用于其他同类桥梁结构施工控制。

Based on the cantilever erection of CFST rib, the relationship of several alignments in the process of construction is discussed and some advices for control of the alignments are presented. Consequently a new method applicable to calculate and control the erection alignments are proposed. This method can be of reference to the construction of other similar kind of bridges
