摘　　要：针对高架桥盖梁临时支撑结构,将托架加贝雷梁的施工工艺作为设计方案,采用大型通用有限元软件Midas,建立托架加贝雷梁的盖梁支架结构有限元模型,分别进行末班支架顺桥向I18工字钢、贝雷梁及托架体系静力有限元计算,最后进行了托架稳定性计算。Temporary support structure for viaduct plate beam,the bracket and bailey beam construction technology as a design scheme of adopting large general finite element software Midas,establish bracket and bailey beam bracket structure finite element model of plate beam,respectively,for the last bridge bracket suitable to I18 beams,bailey beam and bracket system static finite element calculation,finally calculate the stability ofthe bracket.The results provide safety guarantee and suggestions for the construction ofviaduct girder.
