| 摘 要： | 用温克勒(Winkler)地基代替最下层的弹性半空间体,利用Laplace-Hankel积分变换技术及传递矩阵方法推导出了层间完全接触的N层弹性体系在轴对称动荷载作用下的道面弯沉的解析解。最后,给出了道面动态弯沉的数值计算结果表明推导结果的正确性。为今后此种模型下的具体道面结构的动态分析及参数识别工作奠定了一定的理论基础。

| Abstract: | The explicit solution of axisymmetic elastodynamic problem for multilayered elastic body on Winkler foundation is derived by means of Laplace-Hankel transforms and transfer matrix method.The solution can be used for any axisymmetrical dynamic problems where layers are completely contacted.Numerical example demonstrates that the results in this paper are correct.From the results of the paper,the foundation for more detail analysis and parameter identification of pavement structure could be established. |
