| 介绍一个求解参数层状地基动力柔度系数的近似求解方法，这一方法的基本思想是将变参数层状地基等效的为均匀层状地基，这样便可应用目前已经获得的各种解析解的研究成果，使问题简化。 |
| 英文摘要: |
| \ \ A new approach is introduced for obtaining the dynamic flexibility of soil layer with variable physical parameters. In the approach, the basic idea is that the layer is equivalent to a homogeneous layer with same depth. Therefore, the analytical solutions of wave equation for the homogeneous soil layer can be easily applied to the nonhomogeneous soil layer. The equivalent principles are applied to both of the static deformation and the foundational shear mode of the layers. A brief evaluation method for the first mode of the nonhomogeneous soil layer is also suggested. The numerical examples show the approach has good precision. |
