| Abstract: | Qingyi River Bridge locates on NingWu Line.It is a tied-arch bridge with a span of 2＆#215;88m. It only takes a year to complete the construction,although it is close to the existing line.Under the condition of limited clearance,the method of erecting girder first and arch late is used.The construc-tion of the superstructure and substructure is coordinated and implemented by using rapid construction technologies.The way to build the bridge not only meets the requirements of the construction period, but also avoids construction risks very well.The successful completion of the bridge provides practical basis for the similar projects. |
