摘　　要：对不同加筋工况下土工格栅处理加宽路基进行有限元分析,并比较了不同加筋长度下路基的差异沉降、侧向变形及稳定性,分析结果表明,路基扩建加筋效果与伸入老路的加筋长度有关,从而为海南省软基路段的旧路扩建设计提供依据。This paper analysis different reinforcement treating broaden roadbed by geogrid with finite element program. The differential settlement, horizontal displacement and stability of different reinforcement length of broaden road was compared in this paper. The results show that the effect of geogrid reinforcement have relation to the geogrid length in old road, so as to offer the basis for road broaden design with soft soil ground of Hainan province.
