预应力连续箱梁桥悬臂法施工技术的应用

Application of Cantilever Construction Technology for Prestressed Continuous Box Girder Bridge

文章基于预应力混凝土连续梁桥悬臂施工特点,对两种施工方法悬臂拼装与悬臂浇筑的施工方法及施工要求、施工设备等内容进行了相应的探讨。除此之外,笔者又分别从设计、施工进度以及施工设备、施工质量等层面对悬臂拼装与悬臂浇筑两种方法的施工差异进行了探讨,希望为实现更科学、更环保的悬臂施工技术引用提供参考作用。

Based on the characteristics of cantilever construction of prestressed concrete continuous girder bridge, the construction methods, construction methods, construction equipment and so on of the two construction methods cantilever assembly and cantilever pouring are discussed accordingly. In addition, the author discusses the construction difference between the cantilever assembly and the cantilever casting method from the aspects of design, construction progress, con- struction equipment and construction quality, and hopes to provide reference for the realization of more scientific cantilever construction technology reference The
