下穿既有线城市桥梁现浇混凝土箱梁施工技术

Construction Technology of Cast-in-Place Concrete Box Girder of City Bridge Under Crossing Existing Line

以某下穿铁路项目为背景,围绕该项目现浇混凝土箱梁施工技术展开探讨,从下部结构及上部结构施工2个方面分析其施工工艺,并针对其监控量测及控制措施进行分析,旨在提升现浇混凝土箱梁技术的应用水平。

Taking a certain under crossing railway project as the background,this paper discusses the construction technology of the cast-in-place concrete box girder,analyzes the construction technology from two aspects of the construction of the substructure and superstructure,and analyzes the monitoring measurement and control measures,in order to improve the technical application level of the cast-in-place concrete box girder.
