摘　　要：通过对移动模架箱梁施工在模架移动、混凝土浇筑、预应力张拉的荷载作用下的工况分析和施工监测,获得各工况下梁体挠度变化值,经综合分析确定立模预抛值,为此类模架施工预抛值设置提供参考。By way of the operating mode analysis and construction monitor of constructing box girders under the different loads with SL-MSS,the variation values of box girder deflection under various operating modes are collected. The camper of formwork erection is determined via comprehensive analysis. The results may supply references for the camper selection for this kind of box girders construction with the scaffolding system.
