“…83 84 Laboratory experiment is another common approach to investigate the soil response to 85 the wave action. The primary experimental studies mainly include the water flume 86 experiments (Tzang and Ou, 2006;Sumer et al, 2010;Zhang et al, 2016) and 87 cylinder experiments (Zen and Yamazaki, 1990;Liu et al, 2015), which generally 88 focus on the seabed instability induced by liquefaction. However, it is worth of 89 pointing out that the cylinder experiments only consider the excess pore pressure 90 5 induced by macroscopic compression, while the water flume experiments investigate 91 the excess pore pressure evolution characteristics under both the compression and 92 shearing actions.…”

18When ocean waves propagate over porous seabed, they cause variations of the pore 19 pressure within seabed, leading to the possible wave attenuation and soil liquefaction. 20In order to advance and improve our understanding of the process of wave-induced 21 seabed liquefaction and its impact on wave propagation, systematical experiments are 22 on the wave-induced pore pressures, liquefaction depth and wave attenuation in a silt 33 bed. 34 35

“…Due to the significance of the PSR in seabed soil, a few experimental studies have been carried out to study it. For instance, Nago and Maeno [12] and Zen et al [20] investigated the behavior of cohesionless sediments subjected to oscillatory pore pressure with largescale model in 1-g condition. Sassa and Sekiguchi [13] also carried out a series of centrifuge wave tests on seabeds with fine-grained sand.…”

This paper simulates the wave-seabed interactions considering the principal stress rotation (PSR) by using the finite element method. The soil model is developed within the framework of kinematic hardening and the bounding surface concept, and it can properly consider the impact of PSR by treating the PSR generating stress rate independently. The simulation results are compared with centrifuge test results. The comparison indicates that the simulation with the soil model considering the PSR can better reproduce the test results on the development of pore water pressure and liquefaction than the soil model without considering the PSR. It indicates that it is important to consider the PSR impact in simulation of wave-seabed soil interactions.

“…In the previous studies, experiments and analyses on wave-induced liquefaction have been also conducted (Nagano & Maeno, 1987;Zen & Yamazaki, 1990;Sassa & Sekiguchi, 1999). The rapidly decreasing water level brings the pore water pressure gradient, and the pore water pressure gradient causes a decrease in the effective stress.…”
