钢管混凝土拱桥拱肋吊装施工技术

结合祁家黄河大桥主桥拱肋的吊装施工技术,阐述了无支架缆索吊装拱肋的施工技术,实践证明：精心的在缆索吊装法基础上采用千斤顶斜拉扣挂法施工的方法,能够较好的解决大跨径拱桥多节段拼装、扣索系统操作复杂、拱轴线难于控制、施工风险大等问题。

On construction technique of rib-assembling in steel pipe concrete arch bridge

By combining with the rib-assembling construction technique in Qijia Yellow river Bridge,the paper illustrates the non-support cable rib-assembling construction technique.It is proved through the practice that the adoption of the lifting-jack inclined cable-stayed buckle based on the cable assembling method can solve some problems of the large-span arch bridge,such as multi-section assembly,complicated tie cable system,the out-of-control arch axis and high-risk construction.
