基于第一作者提出的弹性波动方程 ,研究了匀质弹性饱和地基的 Lamb问题 .考虑线源和点源两种情形 ,通过 Fourier变换和 Hankel变换 ,导出了 Lamb问题的积分形式解 .通过算例研究了该积分形式解数值实施的可行性 ,给出了地基表面竖向位移的衰减曲线 ,并由此考察了土的渗透性以及激振频率对它的影响 Based on the elastic wave equation proposed by the first author, the Lamb problem of homogeneous elastic saturated soil is studied. The integral form solution of Lamb problem is derived by Fourier transform and Hankel transform, considering both the source and the point source. The feasibility of numerical solution of the integral form is studied. The decay curve of the vertical displacement of the ground surface is given, and the permeability of soil and the influence of excitation frequency on it are investigated
