Abstract: This study investigates the pore water pressure response mechanism and the liquefaction behavior of silty sand seabeds under wave loading through numerical simulations and physical experiments. Using FLAC software, a numerical model was developed to simulate the seabed liquefaction process induced by wave loading. Additionally, a wave flume experiment was conducted to simulate seabed liquefaction induced by wave action physically. Pore water pressure variations under different wave conditions were detailed, and the experimental results were compared with numerical simulations. Results demonstrate that wave-induced excess pore water pressure is most evident in the shallow seabed, with liquefaction depth closely dependent on wave parameters. The numerical and experimental results exhibit strong agreement, offering compelling theoretical insights and experimental validation for wave-induced seabed liquefaction.
