钢结构桥梁超重柔性钢梁大跨顶推施工技术应用研究

Application Research on the Incremental Launching Construction Technology for Larg-Span Overweight Flexible Steel Beam of Steel Structure Bridge

某大型桥梁工程经过综合分析论证,拟采用顶推施工法架设钢梁。论文介绍了顶推施工法的工作原理,具体研究了钢结构桥梁超重柔性钢梁大跨顶推施工技术的施工流程、施工准备工作、技术要点以及施工过程控制要点。

After comprehensive analysis and demonstration of a large bridge project, it is proposed to adopt the jacking construction method to erect steel beams. This paper introduces the working principle of the jacking construction method, and studies the construction process,construction preparation, technical key points and construction process control key points of the jacking construction technology of large span overweight flexible steel girder of steel structure bridge in detail.
