摘　　要：分析了当前拱桥的施工技术,针对等切面悬链线钢筋混凝土箱拱预制进行创新,提出了等切面悬链线钢筋混凝土箱拱预制施工技术,采用专门的预制场地,施工方便,不影响其他工序的进度,节约时间,提高了效率,降低施工费用。通过平面作业,减少了浇筑混凝土等工序的高空作业,降低安全事故发生概率。Analysis of the current construction technology of arch bridge,for the innovation of precast reinforced concrete box arch section catenary,proposes the prefabricated construction technology of reinforced concrete box arch section catenary,prefabricated site,special construction is convenient,does not affect the progress of other processes,save time,improve efficiency,reduce the construction cost.Through plane operation,the work of pouring concrete is reduced,and the probability of safety accidents is reduced.

关 键 词：钢筋混凝土箱拱 平面作业 高空作业
