Long Span Cfst Arch Bridge Cable Hoisting Integrated Construction Technology

This paper taking ZiGui LongTangHe bridge in HuBei province as a project background, studies about the unified construction technology of tower and buckle frame in erection with cableway used in steel pipe-encased concrete arch bridge constructioa Based on the analysis of the construction property of long span steel pipe-encased concrete arch bridge, this paper raises the general scheme and basic structure of unified construction, analyzes the mechanical behavior of unified structure of construction statue, mainly discusses the strength, stiflhess and stability of the unified structure. The paper also adopts dynamic monitor system to ensure the reliability of unified structure during the process of bridge construction, so forms a new perfect technology of erection with cableway, applies it in real project and gets excellent effect.
