【 摘 要 】

Concrete-filled steel tubular arch bridge is a relatively new structure system, because of its unique mechanical properties, it has a good advantage in the construction of modern Bridges. In the course of construction, the arch rib axis and the system beam will have the upper and lower deformation. If improper linear control, the compression performance of the material cannot be fully played after the arch rib is formed, which has a great influence on the state of the bridge. In order to make the arch axis of the bridge more reasonable, this paper takes a concrete-filled steel tube arch bridge with a span 60m as an example. Through theoretical analysis and monitoring, it is found that the line shape control of the bridge is reasonable in the construction stage; the line shape of the bridge stage is basically consistent with the design expectation, and the line type is smooth, the multiple cable adjustment is eliminated and the expected target of the construction period is reduced.
