从二维随机波场的相关理论出发，提出了如何从短周期地脉动（频率＞０．５Ｈｚ）时域信号中计算Ｒａｙｌｅｉｇｈ波弥散曲线，进而反演深层地基剪切波（Ｓ波）速度的理论方法和分析技术，并结合实测信号的分析结果，探讨了该方法的可行性和实用性。
Based on the related theory of two-dimensional random wavefield, this paper proposes how to calculate the dispersion curve of Rayleigh wave from the short-period pulsation (frequency> 0.5Hz) and then to inverse the shear wave (S wave) velocity of deep foundation Theoretical methods and analytical techniques, combined with the measured signal analysis results, discusses the feasibility and practicality of the method.
