摘　　要：文章以弹性波横波速度为参数,利用瑞利面波频散曲线的快速标量传递算法进行正演模拟计算,系统研究软弱层速度对瑞利面波基阶模频散曲线的影响,分析和总结了频率与相速度(f-c)、频率与波数(f-k)、深度与相速度(h-c)等瑞利面波基阶模曲线随软弱层速度变化的规律。In this paper, the formula of fast scalar quantity transfer arithmetic of the Rayleigh-wave dispersion curve has been calculated with transverse wave velocity. It also studies the impact of the weak interlayer velocity on the dispersion curve of the Rayleigh wave, analyzes and sums up the changes of Rayleigh-wave dispersion curve （frequency and wave velocity ： f-c, frequency and wave number ： f-k, depth and velocity.. h-c）with the interlayer velocity.
