摘　　要：缅甸曼德勒大桥主跨(3×224)m连续钢桁拱为中承式刚性拱柔性梁结构,钢梁利用拉索平衡进行悬臂架设。该方法新颖、独特,且技术可靠,为钢梁架设提供了新的方法。The continuous steel truss arches of the main spans （3 × 224 m） of Mandalay Bridge in Myanmar are of half-through rigid arch and flexible girder structures, whose steel girders were erected by the cantilever method balanced by the cable supports. The method of erection applied to the Bridge is novel, unusual and is technically reliable, thus contributing a new way to the erection of steel girders.

关 键 词：拱桥 钢梁 刚性拱柔性梁结构 悬臂架设 桥梁架设
