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.
