预应力连续箱梁桥以其外形简洁、受力合理、施工工艺成熟、行车舒适等独特优势在近年来得到了迅速发展。预应力混凝土连续箱梁桥悬臂施工过程中,已浇筑完梁段的线形在后期施工中是不可调节的,为了保证大桥的顺利合拢及成桥线形满足设计要求,同时使成桥内力控制在设计容许范围内,必须在桥梁施工过程中进行施工控制。本文结合工程案例对预应力混凝土连续箱梁施工要点进了探究,希望对同类型工程起到参考作用。
Prestressed continuous box girder bridge with its simple shape, reasonable force, mature construction technology, driving comfort and other unique advantages in recent years has been rapid development. In the process of cantilever construction of prestressed concrete continuous box girder bridge, the linear shape of the completed beam has not been adjusted in the later construction. In order to ensure the smooth closing of the bridge and the alignment of the arch bridge to meet the design requirements, Within the allowable range, construction control must be carried out during bridge construction. In this paper, the construction case of prestressed concrete continuous box girder is explored in the project case, hoping to play a reference role for the same type of project.
