Research on the Application of Horizontal Rotation Construction Method with Flat Hinge in Cable-Stayed Bridge Construction

Rotation construction method includes building the bridge parallel to the obstacle being spanned (a river, a highway or a railway) and then rotating the superstructure into place. The method can optimize bridge construction in terms of reducing impacts on traffic, safety, and overall project budget and duration. Therefore, the method became so popular that it has been used successfully in about one-hundred bridges in China. In this paper , taking the Suifenhe cable-stayed Bridge as project background, the design idea (single point with flat hinge) of bearing system has been brought forward. The successful rotation construction of Suifenhe cable-stayed Bridge proved the feasibility and technical advancement of the horizontal rotation construction method with flat hinge in similar engineering construction, especially the bridges with symmetry structure.
