Abstract
The construction of vertical cross cast-in-place box girder support method generally adopts the sequence of top to bottom.The current pre-construction of box girder will pose difficulties for the construction of the upper span box girder support method.Based on the successful case of bridge construction on Qingcheng Interchange,this paper explores the construction method of pouring beams on top of beams.Through the design of bridge deck buckle type full hall support and construction techniques such as support installation,preloading,and dismantling,the deformation coordination and unity of the support are ensured,as well as the safety and construction safety of the lower box girder structure.关键词
