Abstract:

During the cast-in-situ construction of the main girder section at the transition pier of a continuous steel bridge, the eccentric force of the cantilever of the cast-in-situ beam section on the pier body will cause verticality deviation of the pier and axis offset of the pier cap. In order to meet the requirements for stress, verticality and axis deviation in the construction quality of bridge piers and pier caps in the specification, the project has implemented four measures: design triangular brackets for transition piers, perform checking calculation on the force of the brackets, reversed pull the brackets, and balance partial bending moment of box girder to pier. So that the verticality and axis deviation of the bridge pier and pier cap are within the allowable range, further to ensuring the construction quality of the transition pier.

Key words: transition pier, verticality, axis deviation, construction quality
