摘　　要：箱梁具有整体性好、施工方便而且受力性能好等优点,已在工程界得到普遍采用。做具体设计时发现,在现阶段的桥梁工程中没有明确箱梁的横隔梁如何计算。经对轨道交通高架常用的中小跨径箱梁分析,通过建模并查看箱梁支反力以及横梁受力情况,在积累较多数据的基础上,得出的模型计算结果与实际情况误差在5%以内。因此,横梁简化计算方法可供工程技术人员借鉴。Box girder has been adopted widely inthe engineering field because of its good entirety,convenient construction and excellent stressperformance.It has not been definite that how tocalculate the cross beam of box girder during thesituation bridge engineering.Through the analysis ofmiddle to small span box girder used in railwaytraffic viaducts, box girder support reaction andcross beam stress have been mastered by ways ofbuilding the model.The error of the calculated databy the model was within 5% , in comparison withthe practical situation.The simplified calculationmethod to cross beam could provide references forengineering professionals.
