| Abstract: | Based on the engineering background of Nantong North Changjiang Road West Extension(Yanhai Highway-Chengbei Avenue)Viaduct,the overall slope adjusting and jacking scheme of continuous curved beam bridge is systematically studied.The solution is proposed how to keep the equal proportion of jacking,to guarantee the jack to be perpendicular with the upper box beam and to limit the horizontal displacement of the jack in the process of slope adjusting and jacking of continuous curved beam.The relative technical scheme and the construction method can be referred for the planning and reconstruction of the similar bridges. |
