摘　　要：以黑山南北高速公路连接线处的DRCKA桥为研究对象,对其桥墩处横梁建立若干局部分析模型,参考国内横梁分析方法提出了恒载及活载的施加方式,进而对其进行配筋及裂缝计算,并与该桥整体结构模型分析的结果进行了对比。结果表明,所述横梁局部分析模型计算结果能够较好地与整体结构模型计算结果相吻合,在实际工程应用中可采用局部模型进行计算,以简化横梁计算工作。In the paper,the DRCKA bridge on the access roads of Montenegro North-South Highway is taken as the research object,some local analysis models for the beam at its pier are established,and by referring to the domestic analysis method of crossbeam,the construction methods of dead load and live load are put forward,then its reinforcement and cracks are calculated.By comparing with the results of the whole structure model analysis of the bridge,the results show that the local analysis model of the beam described in this paper can be in good agreement with those of the whole structure model.In project applications,the local model can be used to simplify the calculation of the beam,which can also provide a reference for similar projects at home and abroad.
