Abstract: Abstract: Based on the Scholte wave model with halfspace ocean bottom, the bottom model was extended to the horizontalstratified medium. With the wave equation of fluids and elastic solids in cartesian coordinates, the solution to Scholte wave, which was based on layered elastic ocean bottom model, was proposed. The particle orbits and displacement were also discussed using the normal modes theory. The influence of ocean environments (including sound speed profile and ocean bottom parameters) on the propagation of Scholte wave was studied. The simulation results show that the shearwave of elastic bottom has the greatest influence on Scholte wave, and the inflexion of its dispersion curve can be used to estimate the thickness of sediment.
