摘要
通过对大跨度钢管混凝土拱桥拱肋分段扣挂悬拼施工的介绍,利用吊装扣挂体系的几何关系,推导出交界墩墩顶水平位移与拱肋标高改变值之间的关系表达式。
This article illustrated construction techniques of arch rib assembling of concrete-filled steel tubular arch bridge with great span. Using of the geometric relationship of hang system, it derived a relational expression between the horizontal displacement at juncture pier＇s top and the variations of arch rib elevation.
