Abstract: In order to make the bottom smoothness of the precast bridge decks meet the welding precision requirements of the pre-burying stud shear connector, and make the board splicing precision of precast bridge decks meet the design requirements, the precision control study was carried out for the bottom smoothness of the precast bridge decks and the manufacturing process of the joints between decks. It is proposed that the adjacent bridge board can be continuously standardized, and the inter-board joints can be adapted to meet the design and construction precision requirements. Strictly controlling pre-burying precision of assembled stud shear connector and using rigid formwork can ensure the bottom surface smoothness, which meets the joint requirements of weld seams between the steel vertical plates of PCSS shear connector and the top surface of the steel truss. The engineering practice indicates that the proposed method is simple and feasible, which can meet the accuracy requirements and is available for similar bridges to reference.
