| 摘 要： | 采用ANSYS软件计算分析不同公路等级的路基工作区深度，考察路基加固厚度和强度对路基工作区深度的影响。研究结果表明，路面结构厚度对路基工作区深度有显著的影响，路面结构厚度越厚，路基工作区深度越小，高等级公路的路基工作区深度比二级公路小；在加固强度一定的情况下，增大加固厚度可显著降低二级公路的路基工作区深度，而对高等级公路则效果甚微；在加固厚度一定的情况下，提高加固强度能显著降低路基工作区深度；与增大加固厚度相比，提高加固强度是一种更为有效的方法。

| Abstract: | With ANSYS software，depth of subgrade workspace for different highway classes is calculated and analyzed to study how the thickness and strength of subgrade reinforcement affect such depth.The results show that the structural pavement thickness influences the depth to a great extent that the larger the thickness is，the smaller the depth is，and the depth for highway in higher class is smaller than that for the ones in class II；in case of a given strength，increasing the thickness thereof may reduce the depth for highway in class II greatly，but minor effect would be obtained on highway in higher class；in case of a given thickness，enhancing the strength thereof may reduce the depth greatly；accordingly，compared to increasing the thickness，the enhancement of strength of reinforcement is a method having higher efficiency. |
