Construction of Auxiliary Navigation Opening Bridge of Donghai Bridge

Xuefei Shi

Abstract

The auxiliary navigation opening bridge of Donghai Bridge is a four-span prestressed concrete continuous box girder bridge. It is different from usual continuous box girder bridge because it has non-balanced cantilever segment. The displacement of this kind of continuous box girder bridge is large so that its construction and construction control are more difficult than usual continuous box girder bridges. In this paper, the construction of station K6 bridge of auxiliary navigation opening bridge of Donghai Bridge is introduced and features of this kind of bridge are analyzed.
