| 摘 要： | 根据京津塘高速公路工程地质条件和处理方法建立模型，运用现场试验所获得的参数和FLAC^3D程序对软土地基的变形进行了数值模拟，对地基沉降，尤其是路基表面沉降进行了分析．为了缩短沉降固结的计算时间，采用等效渗透系数，模拟结果与实际基本一致．

| Abstract: | Based on the geological condition and treatment method of Jing Jin Tang highway project,a model is established. With parameters acquired from the site experiment and the ELAC3D program, the deformation behavior of soft base is simulated, and the settlements of the ground, especially of the surface are analyzed. The equivalent permeability parameter is used to decrease the time of calculation for settlement consolidation. The results are similar with practice. |
