dc.description.abstractA standing wave in front of a seawall may reach a height more than twice of its incident component. When excess pore pressure occurs, it may even induce seabed instability, hence endangering the structure. This issue was studied previously using only linear wave theory. In this paper, standing-wave theory to a second-order approximation is applied, in order to demonstrate the differences between these two solutions. The spatial and temporal variations in the instantaneous pore pressure are first calculated, in addition to their vertical distributions. The effects of wave height, water depth and the degree of soil saturation on pore pressure distributions are then discussed, followed by the net pore pressure averaged over one wave cycle. The results suggest the existence of a residual pore pressure in the seabed and its net pore pressure can be used to estimate the wave-induced liquefaction potential in a soil column. It also indicates that, in deep water, the second-order solution predicts that a negative pore pressure at an antinode which may be greater than a positive pressure. Overall, the second-order solution is found to agree better with the experimental results of the pore pressures available, compared to the linear solution.
