Abstract
This article deeply discusses the key links of the plane rotation construction technology for continuous beam bridges on highways,and applies the plane rotation technology to the construction of continuous beam bridges.Firstly,the rotating pier cap of the continuous beam bridge is erected;Then,the box girder is rotated and pushed forward to facilitate the installation of the hanging basket and the closure section;Final-ly,based on the actual construction conditions,determine the construction process flow and monitor the displacement of the selected test points in the project.The results show that with the proposed technology,the vertical amplitude of the measuring points is less than 1 mm,and the ro-tation process is smooth,which meets the technical requirements for the planar rotation construction of continuous beam bridges on highways.关键词
