通过利用ANSYS有限元软件,分析了不同重载交通条件下临离高速公路黄土路基工作区深度。通过分析,发现现行规范使用的路基工作区0.8m的路基工作区深度不符合重载交通实际影响深度,应该提高。在实际路基施工中要充分压实0.8m以外的区域,以保证路基的整体强度。路基工作区深度随车辆轴载的增加而增加,深度大约在1～2.5m范围内。
By using ANSYS finite element software, the depth of loess subgrade working area under the condition of different heavy traffic is analyzed. Through the analysis, it is found that the depth of the embankment work area of 0.8m subgrade working area used by the current code does not meet the actual impact depth of heavy traffic and should be improved. In the actual subgrade construction to fully compaction of 0.8m outside the area to ensure the overall strength of the subgrade. The depth of subgrade work area increases with the increase of vehicle axle load, and the depth is about 1 ~ 2.5m.
