摘　　要：新建大张高速铁路温家窑特大桥主跨转体连续梁上跨铁路中跨合拢施工时,采用了钢盒进行合拢段的施工新技术,合拢段的所有施工均在钢盒内进行,对铁路行车基本无干扰,不仅完全确保了铁路行车安全,且不需搭设铁路安全防护棚,减少铁路封锁要点的时间及次数,大幅降低了施工成本。In the closure for midspan bridges of the swing construction of a continuous beam across the railway of the new constructed Datong-Zhangjiakou high-speed railway Wenjiayao super major bridge,all the construction of closure sections is taken in the steel boxes,which has no disturbance to the railway traffic,not only ensures the safe running of railway,but also has no railway safety protection shed,so as to reduce time and the number of the railway points blockade,greatly reducing the construction cost.
