摘　　要：通过有限元方法,计算分析轻质填料在路堤加宽工程中的地基变形特性。结果表明:轻质填料直立式填筑与斜坡式填筑效果接近;随填土高度增加,地表沉降增速放缓;地表沉降主要来自于浅层软弱土体的固结沉降;深部下卧层土体特性对地表沉降影响较小。The finite element method is used to analysis the foundation deformation of lightweight filling method in embankment widening. The results show that the vertical filling effect of light fill is close to the slope filling effect. With the increase of fill height,the increase of surface settlement slows down. The surface settlement mainly comes from the consolidation settlement of shallow soil. And the deep underlying soil has little influence on surface settlement.
