摘要
以实际工程为例,在分析山区特大公路钢桁梁斜拉桥施工方案时,详细论述了山区特大公路钢桁梁斜拉桥的施工技术,并从施工可行性、施工优缺点、施工工期、大型临时结构和结构施工安全性等角度开展了全面的研究和比较,最终确定使用双悬臂对称施工技术。经实践证明,该技术能显著提升山区特大公路钢桁梁斜拉桥的施工质量。
Taking the actual project as an example, the paper discusses the construction technology of steel truss girder cable-stayed bridge in mountain super highway project in detail when analyzing the construction scheme of steel truss girder cable-stayed bridge, carries out a comprehensive study and comparison from the aspects of construction feasibility, construction advantages and disadvantages,construction period, large temporary structure and structure construction safety. Finally, the double cantilever symmetrical construction technique was used. The practice proves that this technology can significantly improve the construction quality of steel truss cable-stayed bridge in mountainous area.
