Recently studies reveal that the viscoelasticity of the asphalt layer, the transverse isotropy of each structure layer and the foundation condition of the pavement structure are important factors when analysing the data from falling weight deflectors. However, these factors have not been considered in present analytical solutions simultaneously. To fill this gap, the wave propagation approach was extended to establish a new analytical solution. It was shown that the wave propagation approach could eliminate the positive exponential functions in matrix and only matrix with four elements was adopted in calculation, which contributed to an immense improvement in computational stability and efficiency. A subroutine for transversely isotropic viscoelastic material in finite element software ABAQUS was developed to verify the accuracy of the proposed analytical solution. Several numerical examples were also presented to discuss the influences of the aforementioned factors on the dynamic responses of asphalt pavements.

最近的研究表明，沥青层的粘弹性、各结构层的横向各向同性和路面结构的基础条件是分析落锤导流板数据的重要因素。然而，这些因素并没有在目前的分析解决方案中同时考虑。为了填补这一空白，波传播方法得到了扩展，以建立新的解析解。结果表明，波传播方法可以消除矩阵中的正指数函数，仅采用四元矩阵进行计算，极大地提高了计算的稳定性和效率。开发了有限元软件ABAQUS中横向各向同性粘弹性材料的子程序，以验证所提出解析解的准确性。还给出了几个数值例子来讨论上述因素对沥青路面动力响应的影响。
