摘　　要：将相关论文[1]中得到的饱和土一维简谐响应解析解,应用到饱和土中两类压缩波的独立作用、饱和土中波的传播速度、u-p方程的适用范围等研究中。在两类压缩波的独立作用研究中,克服了以前文献中的数学不严密性。研究了饱和土各参数对三种体波波速的影响。通过比较u-w和u-p方程的解答,定量地说明了u-p方程的适用范围。The analytical solution of 1-D harmonic response in saturated soil, derived in the companion paper[1], is used in the research of individual contributions of two compression waves, wave velocity and the applicable scale of u-p formulation in saturated soil. Mathematical imprecision is overridden in the research of individual contributions of two compression waves. The influence of each parameter on the velocity of three volumetric waves is studied. The applicable scale of u-p formulation is quantitatively presented by comparison of the results of u-w and u-p formulation.
