In view of the limitations of traditional bridge swivel construction attitude adjustment by relying on experience and trial and error,the potential advantages of the calculation model in attitude adjustment were analyzed,as well as the application prospects in improving construction efficiency and saving construction period,etc.,a calculation model suitable for attitude adjustment of bridge swivel construction was proposed.Considering the actual constraints in bridge swivel construction and combining with the existing construction experience,the technical process of attitude adjustment was optimized to realize the optimization of attitude adjustment.The effectiveness and feasibility of the proposed optimization method have been verified through its application in the continuous beam swivel construction project of the Tianjin main canal of South-to-North Water Diversion Project.The practice proves that the optimization method can improve the construction efficiency while meeting the specification requirements.The successful application of the attitude adjustment optimization based on the calculation model in the swivel construction of bridge promotes the development of the field of attitude adjustment in the swivel construction,reduces unnecessary waste of resources,provides reference for optimization problems in other engineering fields,and provides strong support for the promotion of the calculation model and specific construction technology in the field of swivel engineering.
