| 摘 要： | 通过分析老路拓宽工程中差异沉降研究的现状,指出了目前计算方法的不足。结合通用有限元程序AN SY S,运用粘弹性材料来模拟土体的非线性,对老路拓宽工程进行了非线性有限元分析,总结了差异沉降的规律,并依据计算结果对老路拓宽的设计提出了建议。

| Abstract: | Through analysis of actual studing the differential settlement of widened road,the shortages of present calculate method are indicated.Integrating with general purpose finite program ANSYS,viscoelastic materials are chosen to simulate the non-linearity of soil.The finite element analysis of widened road is given,the law of differential settlement summarized and the suggestions for the design of widened road are put forward based on the computed results. |
