采用基于弹性层状理论体系的BISAR软件,分析比较了有无铺面结构下的路基竖向附加应力沿深度方向的分布,提出考虑铺面结构下的路基工作区深度是合理的,与实际情况相吻合。同时将该结论运用到依托工程路基工作区深度的计算,为该地区路基地基处理深度提供参考。 Using BISAR software based on the elastic layered theory system, the vertical distribution of vertical subgrade stress in the presence or absence of pavement structure is analyzed and compared. It is reasonable to consider the depth of subgrade work area under the pavement structure, which is consistent with the actual situation . At the same time, this conclusion is applied to the calculation of the depth of work area of ​​subgrade based on engineering so as to provide reference for the depth of subgrade treatment in this area.
