The relationship between the dispersion curve of Rayleigh wave and the structure of multilayered media is nonlinear, so the inversion method of the dispersion curve should be nonlinear. In this paper the authors applied the Quasi-Newton method to the inversion of the fundamental mode, with good effects obtained. With a practical example, the method was verified.
