| 摘 要： | 东海大桥辅通航孔桥为4跨预应力混凝土连续箱梁桥。它与普通的连续箱梁桥的不同之处在于具有非对称悬浇节段。这种连续箱梁桥在施工过程中挠度大。施工和施工控制的难度比普通的连续箱梁桥大。本文对东海大桥辅通航孔桥中的K6桥的施工做了介绍，分析了这类桥梁的特点。

| 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. |
