论桥梁预应力混凝土箱梁预制施工与安装实践

Prefabricated Construction and Installation Practice of Bridge Prestressed Concrete Box Girder

为有效地确保箱梁预制工程施工质量、规范箱梁预制施工作业程序,通过某桥梁预应力混凝土箱梁预制施工实例,结合箱梁预制工程的施工特点以及笔者工程施工经验,探讨后张法箱梁预制施工技术,可为同类工程提供参考和借鉴。

In order to effectively ensure the construction quality of the box girder prefabricated projects and specify the operating procedures of beam prefabricated construction, through a prefabricated construction example of prestressed concrete box girder of one bridge, combined with the characteristics of box girder precast works and the construction experience, this paper explores the post-tensioned box girder precast construction technolo- gy. It can provide a reference for similar projects.
