抚顺万新大桥为主跨 16 0 m 的自锚式钢筋混凝土悬索桥 ,主梁采用单箱 5室钢筋混凝土箱梁 ,主缆每根索股首尾相连形成环绕闭合结构。介绍了主梁滑动模架施工、鞍座安装、环绕闭合钢丝绳主缆无猫道施工、索股下料误差的解决、体系的转换施工等 。
The Wanxin major bridge in Fushun City is a reinforced concrete self-anchored suspension bridge with main span 160m.The main girder is a single reinforced box with five rooms. The strand head and tail connects each other to become the stemming oval main cable.
