A number of studies focus on the pore-water pressure in seabed under the waves and seabed instability induced by liquefaction, but rarely on the wave pressure of liquefied soil. In this paper, flume tests were performed at varying wave heights under both conditions of liquefied and stable seabed. The total pressures equal to soil pressures and pore water pressures were measured and analyzed at each depth. The results showed that the liquefied seabed had little difference from the stable seabed on the peak pressures. However, the pressure amplitude of the liquefied soil increased by several to 10 times and decreased faster with increasing soil depths, compared with the stable soil. According to the experiments and further analysis, an empirical equation between pressure amplitude of the liquefied soil and wave parameters was put forward under the flume test. The results provide a valuable reference for engineering applications.
