水和荷载作用是沥青路面早期损坏的主要原因之一，为研究水对沥青路面的影响，利用积分变换和传递矩阵的方法推导了FWD动荷载作用下路基路面层状粘弹性体超孔隙水压力轴对称问题的解析解。通过引入F．durbin方法实现Laplace逆变换的数值方法，求解了层状粘弹性体的时域解，并给出了算例。结果证明，该方法概念清晰，公式简洁，易于应用。

The moisture and loading action is the primary factor of initial failure for asphalt pavement at first. To study impact on water to asphalt pavement, the solution has been derived by means of the transference of matrix and integral transformation to the axis - symmetrical problems of super - pressure of the multi - layered viscoelastic body in small opening water on asphalt pavement in the FWD dynamic case. F. Durbin＇s numerical solution to inversion transformation of Laplace has been successfully introduced to solve multi - layered viscoelastic problem in time filed. This method is clear in concept, and the corresponding formulas given in the paper are not only simple but also convenient for application.
