    Abstract

    In this paper, the residual mechanism of the non-linear wave-induced pore water pressure accumulations in marine sediments is examined. Unlike previous investigations, the second-order Stokes wave theory is considered in this study. The new model is verified with experimental data and provides a better prediction of pore pressure accumulation than the previous solution with linear wave theory. The parametric study concludes that the influences of wave non-linearity becomes more significant as either wave steepness (H/L) or residual parameter (a) increases. However, an opposite trend is found for another residual parameter (ß).
