Research on Construction Control of Long-Span Prestressed Concrete Continuous Girder Bridge

On the background of 318 highway bridge of the Yinjiang Jihan Navigation Project, it introduces the methods and contents of the construction control of long-span prestressed concrete continuous girder bridge, it adopts Midas/Civil softwares to have a simulation analysis and effective control for the construction process of whole bridge. The result indicates that safety of the bridge construction, linear and the variation of prestress are all in control. Finally, the condition of structure of bridge suits for computational state theoretically.
