Taking the continuous beam bridge along Hangnan road of No. 2 phase project of waterway treatment along Dalu expressway,the paper explores the hanging basket cantilever section construction technique,surveys the general layout,main structural design and prestressed system layout of the bridge,calculates the internal force and stress of the bridge structure,and undertakes the statistical analysis of the evaluation of sim-ilar bridge structural parameter,so as to provide some reference for similar construction.%以大芦线航道整治二期工程航南公路连续梁桥为例，探讨了工程采用的挂篮悬臂节段施工技术，概述了大桥的总体布置、主梁结构设计及预应力体系布置等，并对桥梁结构内力和应力进行了计算，统计了类似桥梁结构参数的取值，为同类桥梁的设计及施工提供借鉴。
