Forward dispersion curves is one of the most important steps of Rayleigh wave data processing. Forward modeling is the premise and basis of inversion. Fast and stable forward method is uesd to improve the efficiency of the calculation, and reduce the time of the use of the protection. According to the research at home and abroad, this article introduces the basic principles of fast scalar transfer algorithm proposed by Fan Youhua. Respectively, three different geological models of the dispersion curves forward calculation are introduced to obtain the dispersion characteristics in different geological conditionscompared with RT matrix algorithm. Numerical simulations experiments show that the fast scalar transfer algorithm is a fast and stable forward calculation method.
