Numerical modelling of liquefaction in loose sand deposits subjected to ocean waves

Abstract: The failure of marine structures is often attributed to liquefaction in loose sand deposits that are subjected to ocean waves. In this study, a two-dimensional integrated numerical model is developed to characterize the liquefaction behaviours of loosely deposited seabed foundations under various types of ocean waves. In the present model, Reynolds-Averaged Navier-Stokes (RANS) equations are used to simulate the surface wave motion, and Biot's consolidation equations are used to link the solid-pore fluid inter… Show more

“…The primary focus is on time-matching schemes, nonmatching mesh strategies, and ensuring the continuity of the interface pressure. The one-way coupling technique has been utilized in previous studies for wave-seabed-structure interactions [50][51][52], yielding notable results in achieving a balance between computation cost and accuracy. Figure 2 provides the schematic representation of the one-way coupling process between the two models.…”

“…Based on Biot’s consolidation theory [ 2 ], several researchers have proposed analytical solutions for wave-induced pore pressure on both finite and infinite seabeds [ 3 , 4 ]. Over time, more complex conditions have been investigated, including multi-layered seabeds [ 5 ], cross-anisotropic soil behavior [ 6 ], non-homogenous seabeds [ 7 ], fully dynamic soil behavior [ 8 ], combined wave and current loadings [ 9 ], and, more recently, the spatial variability of soil properties [ 10 ].…”

“…At present, there are three primary methods for assessing soil liquefaction: in-situ tests (Fergany and Omar, 2017), laboratory tests (Kumar et al, 2020), and numerical simulation (Ye et al, 2016;Zhao et al, 2018). These methods have been maturely applied in the study of liquefaction in sandy soils due to their safety and reliability (Amini and Qi, 2000;Dobry and Abdoun, 2017;Ye et al, 2018).…”
