摘　　要：为合理确定黄土填方路基竹筋格栅加筋方案,利用有限元软件进行数值分析。分未处治和竹筋格栅加筋两种情况进行对比分析,得出加筋后路基顶面沉降、水平位移和基底竖向应力均明显下降,路基承载力提升,说明采用竹筋格栅加固可限制路基变形,改善路基受力状况。因此,采用竹筋格栅加筋处治后路基稳定性得到了提升,施工方案可行。The finite element software was used to conduct the numerical analysis to reasonably determine the loess filled subgrade's reinforcement scheme with bamboo geogrid.By comparing two situations of untreated subgrade and bamboo geogrid reinforced subgrade,it was concluded that after the reinforcement,the settlement at the subgrade top surface,the horizontal displacement of the subgrade,and the vertical stress of the subgrade base were all decreased,and the bearing capacity of the subgrade was improved.It indicated that the bamboo geogrid reinforcement can limit the deformation of the subgrade and improve the subgrade stress.Therefore,the stability of the subgrade reinforced with the bamboo geogrid was enhanced,and the construction scheme was feasible.
