摘　　要：蚌埠市大庆路淮河公路桥采用顶推施工技术。结合工程的实际概况,对钢箱梁顶推施工提出2种不同的施工方案,一是传统的拖动式顶推,二是步履式顶推方案。采用有限元软件对2种施工方案进行对比分析,选出适合工程条件的优化方案。The main bridge of Bengbu Daqing Road Huaihe River Highway Bridge adopting pushing construction technology. Combined with the engineering practical overview, put forward two different construction schemes for incremental launching construction of the steel box girder, One is the traditional drag pusher, a walking type pushing scheme. Comparative the two construction program using the finite element software, elected optimization program for engineering conditions.
