In this paper, using multi-layered homogeneous isotropic elastic model, considering the continuity of displacement and stress at the interfaces, the free surface condition and the infinite radiation condition, we deduce the dispersion function of axis-symmetrical cylindrical Rayleigh wave in multi-layered media with cylindrical coordinate. We get good results from the numerical computation. This method could have some theoretical effect on the application of Rayleigh wave in engineering.
