摘要
丹东月亮岛大桥是宽跨比为 1 /2 2 .44的下承式钢管混凝土系杆拱桥 ,采用单片桁架式 X型拱肋 ,利用桥面板内张拉钢铰线作为桥梁的系杆 .通过对该桥施工控制中采用的计算方法及施工中关键问题的分析 ,为该桥提出了合理的施工方案 .
Dandong Moon Island Bridge is a through concrete-filled steel tubular (CFST) X type tie arch bridge with ratio 1/22.44 of width of deck to span. The section of the arch ribs adopts monolithic truss type,and the tie bar adopts the deck of the bridge. By analyzing the analytic method and some key questions in the erection of the structure,the rational construction method is provided. It can give a reference to the construction supervisory of long-span concrete filled steel tubular narrow tied arch bridge.
