SUMMARYThe residual mechanism of wave-induced pore water pressure accumulation in marine sediments is re-examined. An analytical approximation is derived using a linear relation for pore pressure generation in cyclic loading, and mistakes in previous solutions (Int. J. Numer. Anal. Methods Geomech. 2001; 25:885-907; J. Offshore Mech. Arctic Eng. (ASME) 1989; 111(1):1-11) are corrected. A numerical scheme is then employed to solve the case with a non-linear relation for pore pressure generation. Both analytical and numerical solutions are verified with experimental data (Laboratory and field investigation of wavesediment interaction. Joseph H. Defrees Hydraulics Laboratory, School of Civil and Environmental Engineering, Cornell University, Ithaca, NY, 1983), and provide a better prediction of pore pressure accumulation than the previous solution (J. Offshore Mech. Arctic Eng. (ASME) 1989; 111(1):1-11). The parametric study concludes that the pore pressure accumulation and use of full non-linear relation of pore pressure become more important under the following conditions: (1) large wave amplitude, (2) longer wave period, (3) shallow water, (4) shallow soil and (5) softer soils with a low consolidation coefficient.

“…This framework was further extended to the three-dimensional short-crested wave-induced seabed response in a seabed of finite thickness (Hsu and Jeng, 1994) and a layered seabed (Hsu et al, 1995). Later, many theoretical studies for more complicated wave and seabed conditions were reported: for example, crossanisotropic soil behavior (Jeng, 1997a;Kitano and Mase, 1999); nonhomogenous seabed (Jeng and Seymour, 1997;Kitano and Mase, 2001); inertial effects (Jeng et al, 1999;Jeng and Rahman, 2000;Ulker et al, 2009); fully dynamic soil behavior (Jeng and Cha, 2003;Ulker et al, 2009); and, recently, combined wave and current loadings (Ye and Jeng, 2012;Wen et al, 2012;Zhang et al, 2013;Liu et al, 2014).…”

“…Among these, Yamamoto et al (1978) considered two-dimensional progressive waves over isotropic and homogeneous seabed with infinite thickness. Later, some progress has been made by considering anisotropic and nonhomogeneous seabed behaviors (Jeng, 1997;Jeng and Seymour, 1997;Kitano and Mase, 1999). In addition to analytical solutions, numerous numerical models and experimental works have been reported in the literature (Cuomo, Allosp, and Takahashi, 2010;Jeng and Lin, 1996;Kudella et al, 2006;Sassa et al, 2006;Wen, Jeng, and Wang, 2012;Zen and Yamazaki, 1990;Zhang et al, 2009).…”

Liu, B.; Jeng, D.S., and Zhang, J.S., 2014. Dynamic response in a porous seabed of finite depth to combined wave and current loadings. Journal of Coastal Research, 30(4), 765-776. Coconut Creek (Florida), ISSN 0749-0208.In this study a u-p approximation for the dynamic response of a porous seabed to nature dynamic loadings is proposed. Unlike most previous research, the effects of currents are considered in the new analytical solution. Based on the numerical examples, the significant influence of combined wave and current loadings on seabed response in shallow water is concluded. This influence affects not only the amplitudes of the seabed response but also the distributions of the space region. The relative difference of the maximum pore pressure between different direction currents can reach 8% of the static water pressure. In addition, the relative difference of maximum liquefaction depth between the previous model (without currents) and the present model can reach 19% of the maximum liquefaction depth of the case without currents.ADDITIONAL INDEX WORDS: Current, third-order wave/current interaction, liquefaction, pore pressure.
