| Abstract: | Bowl- shaped box girder has a complicated configuration and structural behavior, which brings great difficulty in the design and construction of framework and also concrete east. By taking a practical bridge as engineering example, study and practice on the construction of bowl - shaped concrete box girder have been conducted, and some favorable construction techniques are also concluded and prooved to be efficient, which provides practical guidance for constrution of similar bridges. |
