Span Steel Tubular Concrete Tied Arch Rib Construction And The Construction Of Vertical Transfer Method Study

Arch rib is the key point during the process of the long-span concrete-filled steel tube arch bridge construction. This paper introduces the development and present situation of concrete-filled steel tube arch bridge in the world; generally analysis the mechanism, construction technology, construction equipment of the job practice; advance the entire scheme of the long-span concrete-filled steel tube arch rib construction; at last give the analysis the concrete scheme of the concrete-filled arch rib construction. This paper declares the reference value of the study through the above.
