-
摘要: 本文从柱坐标系下弹性力学基本方程出发,经关于方位角的Fourier变换及关于径向的Hankel变换,建立了介质层的传递矩阵,利用层间完全接触条件,给出了多层半无限弹性体在任意荷载作用下的理论解。由于不必要引入应力函数,所以,本方法概念清晰、易懂、便于实际应用。Abstract: By means of the Fourier-Hankel mixed transform, the explicit solution for layered half-space under arbitrary loading is derived driectly from the essential equation based on the displacement method for three-dimensional nonaxisymmetrical problems. This method is clear in concept, and the corresponding fomulas given in the paper are simple and covenient for application.
