摘要
基于第一作者提出的饱和土弹性波动方程，本文提出了饱和地基中端利波的频率特征方程，并由此分析了瑞利波传播速度和衰减系数随振动频率、土渗透系数等因素而变化的规律性。研究表明，在低频和低渗透条件下，饱和地基中瑞利波的速度符合经典波动理论公式，其值受第二P波的影响甚微。
Based on the theory of elastic wave in saturated soils estabblished by the fundamental equaations of Rayleigh wave in a saturated soil ground are derived herem.Analysis shows that the calssical theory for a singl-phased elastic soild could be used for calculation of the propagation velocity fo Rayleigh wave in a saturated soil ground at low frequency and/or permeability,which is almost not influenced by the second P-wave in the saturated soil.
