Suspender tension and cable adjustment are important construction procedures in the construction of through arch bridges. The traditional suspender tension method is asynchronous tension. Because it is tensioned in batches and manually reads, it will cause errors in the control of suspender tension, which often fails to reach the tension accuracy. Therefore, it is necessary to determine whether secondary cable force adjustment is needed according to the site conditions, which may increase the construction period, management cost and construction cost. In this paper, the overall intelligent synchronous tensioning technology is applied to a through arch bridge. By monitoring the measured suspender cable force, structural deformation and structural stress in the synchronous tensioning process and comparing them with the theoretical values, the traditional asynchronous tensioning technology and intelligent synchronous tensioning technology are compared based on the finite element software. The influence of the error caused by asynchronous tensioning on the structure is analyzed and compared with the suspender cable force, structural stress and structural deformation in the synchronous tensioning process. The results show that the bridge is relatively sensitive to the tension cable force, so it is necessary to accurately control the construction cable force. The overall intelligent synchronous tensioning technology can control the error of the suspender cable force within 3% during the bridge completion process, the geometric shape error of the whole bridge is controlled within 4mm, and the stress error is within 7MPa, avoiding the secondary cable force adjustment. It not only reduces the structural stress generated during the construction of the suspender, but also saves the construction period and construction cost, and ensures the safety of the construction process.
