... pressure. When the pore pressure extreme growth, the effective stress will decrease, which will lead to instability of the soil as the consequence of the horizontal or vertical movement of the soil particles, resulting in instability of the soil (Sumer, 2014). Therefore, determining pore-water pressures...

... pipelines may be exposed due to wave-induced liquefaction of underlying seabed soil layers. Generally, the fluctuating pressures acting upon the seabed due to progressive motion of ocean waves will further induce excess pore pressure and reduce the effective stress within seabed soil. When the excess pore...

... distribution pattern of pore pressure by changing the wave shapes. Introduction Wave-induced porous seabed response plays an important role in the mechanism of seabed instability around marine structures. Distribution of pore pressure in the seabed is mostly concerned as it may cause destruction of surface...

... Abstract The wave-induced pore pressure is a key factor in the prediction of the wave-induced liquefaction potential, which has been reported in the literature in conjunction with marine engineering (Sumer and Fredsøe, 2002). Most previous investigations for the wave-induced soil response have...
