为探究水-荷载耦合作用下的沥青路面车辙变形特点。基于Biot理论，运用有限元数值模拟方法，对比分析水-荷载耦合作用与单独荷载作用下的沥青路面车辙变形规律。分析结果表明：水-荷载耦合作用下的沥青路面车辙变形量及变形速率低于单独荷载作用，密闭于沥青路面联通空隙内部的水一定程度上有助于沥青路面的抗变形能力；水-荷载耦合作用与单独荷载作用下沥青路面的车辙变形比与荷载循环作用次数呈对数函数，且随着荷载循环作用次数的增加而降低。

In order to analyze the characteristic of rutting deformation of asphalt pavement under moisture-load coupling action,this paper compares and analyzes the rutting behaviors of saturated asphalt layer and dry sur-face layer by using FEM. The result indicates that the rutting depth is lower under saturated condition than dry condition,and the creep slope of asphalt layer under saturated condition decreases,compared to the asphalt lay-er under dry condition. The rutting deformation ratio between moisture and dry condition follows the log func-tion relationship with the loading number,and decreases with the increase of loading number.
