摘　　要：结合通用有限元程序ANSYS,运用Drucker-Prager材料来模拟土体的非线性,分析地基的沉降以及路堤的变形和路面结构层的应力分布,并与实测结果作了对比。总结了新旧路基差异沉降的规律,并依据计算结果对旧路拓宽的设计提出一点建议。With the aid of trmite element program ANSYS, DP model is chosen to consider the non- linearity of soil, the settlement of the ground, the deformation of the embankment, associated with their stress distribution are analyzed. Additionally, the computed solutions are compared with those of in - site measurement. The law of the differential settlement is summarized, and some suggestions on the design of widened road are presented in the paper.
