预应力混凝土连续箱梁现浇技术探讨

摘要

通过结合某预应力混凝土连续箱梁现浇法施工实例,工程施工中采取移动式挂篮,以桥墩为中心对称向两端利用挂篮逐段灌注梁段混凝土,提出连续箱梁预应力后张法施工以及相应的施工注意事项,为同类工程提供了指导。%Integrating with continuous box girder casting case of the prestressed concrete,movable cradle is used in the engineering construction.Concrete is poured on the beam section by section with the pier as the center.This paper puts forward the prestressed post-tension construction method of continuous box girder and matters needing attention in the construction,which has provided guidance for similar engineering.
