摘要
结合吊钟岩特大桥施工,对劲性钢骨架主弦钢管顶升法泵送混凝土施工技术和质量控制方法等进行了详细介绍,对混凝土灌注阶段钢骨架应力和变形的实测值与设计值进行了比较分析。
Based on the construction of Diaozhongyan Major Bridge, pumped concrete technology for steel tubes of the main chord in an arch bridge erected by swing and the methods of quality control are introduced in detail. The stresses and displacements in the steel skeleton measured during concrete pumping stage are compared with the design values.
