| Abstract: | In this paper,the forward calculation of Rayleigh wave dispersion curves was carried out by using fast scalar transfer algorithm.It has studied the weak interlayer bottom velocity which impact the dispersion curve of the Rayleigh wave,analyzed and summed up the change rules of Rayleigh-wave dispersion curve in the frequency and wave velocity(f-c),frequency and wave number(f-k),depth and velocity(h-c) with the weak interlayer bottom velocity. |
