Research on the Critical Technique of Synchronous Rotation Construction With Large Angle for T-shape Curve Rigid Frame Bridge

Abstract: The superstructure rotation method (SRM) can optimize bridge construction in terms of reducing impacts on traffic, safety, and overall budget. This paper focuses on the key scientific problems of synchronous rotation construction with large angles and takes two T-shaped rigid frame bridges of the Wuyi Expressway over the Chengdu-Kunming Railway as the engineering background. Construction technologies of this project are introduced, including the installation process of spherical hinges, the design of the tract… Show more
