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。
Donghai Bridge auxiliary pass hole bridge for the 4-span prestressed concrete continuous box girder bridge. It differs from ordinary continuous box girders in having asymmetrical cantilever segments. This kind of continuous box girder bridge has great deflection in the construction process, and it is more difficult to control the construction and construction than the ordinary continuous box girder bridge. This paper introduces the construction of K6 bridge in the auxiliary navigation bridge of Donghai Bridge and analyzes the characteristics of such bridges.
