预应力混凝土连续箱梁桥悬臂法施工关键技术

Key Technology of Cantilever Construction of Prestressed Concrete Continuous Box Girder Bridge

预应力混凝土连续箱梁桥是一种施工要求高、施工难度大的新型桥梁,悬臂施工法是预应力混凝土连续箱梁桥施工常用方法。简单介绍了预应力混凝土连续箱梁桥悬臂法施工背景,论述了预应力混凝土连续箱梁桥悬臂法施工技术流程,并对悬臂法施工控制要点与结果进行了进一步分析,希望为悬臂法在预应力混凝土连续箱梁桥中的应用提供一些参考。

Prestressed concrete continuous box girder bridge is a new type of bridge with high construction requirements and great construction difficulties. Cantilever construction method is a common method for the construction of prestressed concrete continuous box girder bridge. This paper briefly introduces the background of cantilever construction of prestressed concrete continuous box girder bridge, discusses the technical process of cantilever construction of prestressed concrete continuous box girder bridge, and further analyzes the key points and results of cantilever construction control, hoping to provide some reference for the application of cantilever method in prestressed concrete continuous box girder bridge.
