基于Boit理论，建立了考虑湿陷性路面响应的控制方程。通过傅里叶级数展开得到了解析解。此外，针对路面的水损伤，研究了渗透系数、交通荷载速度、排水边界和固体模量等参数对路面动力响应的影响。与干弹性路面相比，饱和沥青路面在交通荷载作用下，负的正应力集中，这可能是沥青路面产生破坏现象的原因之一。渗透系数各向异性对物理场的影响很大。在垂向渗透系数和水平渗透系数之间，物理场主要取决于垂向渗透系数而不是水平渗透系数，水平渗透系数对水平孔隙水速度的影响较为明显。另外，排水边界对高渗透性面层的渗流场有明显的影响。
Based on the Boit's theory, the governing equation was established to account for the response of moisture pavement. The analytical solutions were obtained through the expansion of Fourier series. Furthermore, the effects of parameters (i.e. hydraulic conductivity, traffic load velocity, drainage boundary and solid modulus) on dynamic response were investigated in terms of water-induced damage of pavement. Compared with the dry–elastic pavement, the negative normal stress in saturated asphalt pavement is concentrated beneath the traffic load, which may be a reason for a damage phenomenon in asphalt pavement. Hydraulic conductivity anisotropy plays a significant role in influencing the physical fields. Between vertical and horizontal hydraulic conductivity, the physical field almost depends on vertical hydraulic conductivity rather than horizontal hydraulic conductivity which just affects the horizontal pore-water velocity obviously. Moreover, the drained boundary evidently influences the seepage field of surface course with high permeability.
