针对辽西地区风积土特殊的物理力学性质,结合已有的试验结果,利用大型数值模拟软件ADINA对风积土路面结构进行了模拟分析,获得了在轴载作用下风积土路基路面结构的变形特征,数值模拟结果表明,在轴载作用下风积土路基路面结构将同时出现横向和纵向两个方向的位移,且纵向位移较大。不同路基深度处路基的纵向位移变化是不同的。

According to in western Liaoning aeolian soil for the special physical and mechanical properties,combined with existing experimental results,the use of large-scale numerical simulation software ADINA aeolian soil road surface structure of the simulation analysis,obtained axleloads in the aeolian soil subgrade deformation characteristics of pavement structure.The simulation results show that the axial loads in the aeolian soil subgrade pavement structure will simultaneously horizontal and vertical displacement in both directions,and the vertical displacement of large.Different depth of the roadbed subgrade vertical displacement of the different changes.
