| 中文摘要: |
| 膨胀土路基的变形取决于含水量的变化，本文采用ABAQUS对非饱和膨胀土路基的防渗进行分析。研究结果表明：未采取防渗方案时，降雨引起的含水量变化范围最大；在采取防渗方案后，含水量变化范围相应减小；另一方面，防渗越深，含水量变化值越为均匀，变化幅度越小。因此，土工膜防渗可以减小路基的变形。研究结果可为工程设计和数值计算的参数取值提供参考。 |

| Changes of water content determine the deformation of expansive soil subgrade. In this paper , the seepage treatments of unsaturated expansive soil are analyzed by ABAQUS software. The results show that there are small changes in water content value by using anti-seepage measures under the rainfall. Without using anti-seepage treatments, there is a large change at range of water content value. At the same time, the ranges of water content value obviously decrease with the increasing depth of anti-seepage measures. Therefore, deformation of pavement can be decreased by anti-seepage treatments. The results could be used for engineering design and numerical calculation. |
