跨通航河道可提升式便桥施工技术

The Spanning Navigable Channel Lift Auxiliary Bridge Construction Technology

结合合福高铁(安徽段)铜陵长江大桥北引桥跨西河连续梁便桥的施工实例,详细介绍了跨通航河道的可提升式便桥的设计及施工技术,有效地解决了航道通航净空和便桥需要贯通的矛盾,设计合理,简便易行,安全可靠,有较强的实用性,可供类似工程借鉴。

Combined with the construction examples of west river-crossing auxiliary bridge used for continuous beam in northern bridge approach o fTongling Yangtza River Bridge in part o fHeFu High-speed Railway（Anhui Section）,this paper introduces spanning navigable channel lift auxiliary bridge design and construction technology which resolves effectively the contradiction of channel navigation clearance and the auxiliary bridge through.The design and technology which is reasonable,simple,security and reliable,has higher practicability and can be used for re ference by other similar project.
