On box girder construction technique of over-line railway

Taking super-large bridge project along Qinglin road as the example,the paper introduces the foundation treatment,the support structure,the load pre-loading,the manufacture of box girder model,the process of reinforcement and the concrete grouting of the upper continuous box girder cast-in-place construction of over-line bridge,and illustrates the technical measures in the construction,so as to accumulate the construction experience for the over-line bridge construction,so as to direct similar projects.
