| 摘 要： | 基于粗粒料的邓肯-张（E-B）本构模型,采用非线性有限元方法仿真模拟了高填方路基分层碾压填筑的施工过程,预测了路基的变形分布规律。计算结果表明：对于高填方路基,采用薄层填筑、分层碾压的施工方法可有效的控制路基变形,也可为工程提供一定的理论依据。

| Abstract: | Based on Duncan-Chang （E-B） model of coarse-grained materials, nonlinear FEM is adopted to simulate the high fill subgrude construction process of stratified rolling and filling, and the distribution of subgrude deformation is predicted. The results show that： for the high fill subgrade, using thin-layer filling, stratified rolling construction method can effectively control the subgrade deformation, and also can provide some theoretical basis for engineering. |
