摘要
以张家口通泰大桥为背景,介绍斜交曲线下承式钢结构悬索拱桥的预应力施工方法,着重对吊索的安装、张拉和仿真模拟等关键施工环节进行阐述。目前,本工程已经建成并通车,预应力施工取得了很好的效果。
Taking Zhangjiakou Tongtai Bridge as the background, the construction method of oblique cross curve through type steel suspension arch bridge is introduced, the key construction steps such as the installation, tension and simulation of suspension bridge are described. At present, the project has been completed and opened to traffic. Prestressed construction has achieved good results.
