    Abstract

    The phenomenon of wave-seabed interactions has attracted great attentions from marine geotechnical and coastal engineers involved in the design of foundation around marine installations. The effects of currents and dynamic soil behavior have been ignored in most previous research. In this study, an analytical solution for the combined wave and current-induced pore pressures in marine sediments with full dynamic soil behavior will be derived. With the newly analytical solution, the effects of currents, full dynamic behavior and high-order wave characteristics are examined. As shown in the numerical examples, the effects of currents on the seabed response are only significant in the top region of the seabed (around 10% of wavelength).
