Abstract：Aiming at the problem that the arch rib alignment deviates from the target alignment seriously due to too many steel plates inserting into the arch segments during the construction with the cantilever assembly cable-stayed suspension method, the coordinate correction formula of arch segments after inserting steel plates was deduced, according to the geometric relationship between arch segments. The influence of the padded steel plate between arch segments on the cable force and the main arch alignment was also studied by using finite element software. The results of the study show that: in the process of assembling the arch rib, the steel plate padded at the back of the arch will increase the cable force during the construction process, with the cable force error reaching 49.69%; the alignment of the arch rib after the completion of the arch is higher than the target alignment, and the maximum deviation of the alignment will reach 204.9 mm. The steel plate padded at the arch soffit will decrease the cable force in the process of construction, and the cable force error is up to -50.26%; the alignment of the arch rib after the completion of the arch is lower than the target alignment, and the maximum deviation of the alignment will reach -201.9 mm. Therefore, the use of padding steel plates between arch segments should be precautious in the arch segments construction.
