摘　　要：随着经济的发展和交通需求的增加,桥梁建设变得越来越重要。传统的桥梁施工方法往往需要较长的施工周期和大量的人力物力投入。然而,装配式组合钢箱梁的引入为桥梁施工带来了革命性的变化。文章首先介绍了装配式组合钢箱梁桥的施工工艺,接着分析施工阶段单梁静载的影响,最后运用引入松弛系数的满应力齿行法优化求取最大约束值和整体偏移。With the development of economy and the increase of traffic demand,bridge construction becomes more and more important.The traditional bridge construction method often needs a long construction period and a lot of manpower and material input.However,the introduction of prefabricated composite steel box girder has brought revolutionary changes to bridge construction.This paper first introduces the construction technology of prefabricated composite steel box girder bridge,then analyzes the influence of static load of single beam during construction,and finally optimizes the maximum constraint value and the overall deviation by using the full stress tooth row method with relaxation coefficient.
