Research on Construction Technology of Hub Interchange Steel-Concrete Composite Box Girder
Combined with Zhangjiajie-Nanchong Expressway engineering,this paper introduces the construction technology of steel-concrete composite box girder of the main bridge of hub interchange in detail.For the main bridge of the hub interchange,on the basis of on-the-spot investigation of the construction conditions on the site,it is necessary to consider the influence of the transportation and installation of the steel-concrete composite beam on the traffic,and the construction is difficult.A set of feasible construction technologies of steel-concrete composite box girder suitable for hub interchange is summarized,which can provide reference for similar engineering.
