| Abstract: | This paper mainly, combined with the Shanghai Yangtze River Bridge B1 section using 50 m mobile frame, introduces the linear control technology of continuous box girder, including the mobile frame preloading and camber setting method. It covers the theory deflection analysis of mobile frame under allkinds of working condition, pre-pressure data analysis and camber setting, box beam construction control and a series of technologies and construction requirements, which can provide reference for the mobile frame construction of continuous box beam linear control. |
