Concrete-filled Steel Tube Arch Bridge Construction Technology In The Application Of The Third Bridge Of XiPing

As a long-span bridges, concrete-filled steel tube arch bridge structure is a more satisfactory form. In recent years, in our country It is to be a wide range of applications. Due to the lack of systematic analysis and research and information feedback, concrete-filled steel tube arch bridge construction technology need to continue to improve.In this paper, the third bridge of XiPing scor thereen f engineering background of half-through arch bridge CFST choose the overall construction program, construction processes, construction techniques were studied. The study: to determine the economic rational and technologically advanced construction program will take full account of environmental construction, machinery, materials and other factors. Also in accordance with the actual situation at the scene of half-through concrete-filled steel tube arch bridge construction process is optimized, refined. A key point on the construction technology, analysis of the template, frame strength, rigidity, stability, and calculation results based on pre-degree camber settings are discussed. Analysis of the pre-stressed tensegrity systems, such as boom, tied the cord to wear, traction control ,Cam,and construction aspects etc.
