ABSTRACT

In this paper, an experimental study for the wave-induced pore pressure in marine sediments was reported. In the experiment, a one-dimensional facility was set-up with a vertical cylinder and a 1.8 m thick sandy deposit and 0.2 m thick water above the deposit. Unlike the previous experiments in Zen and Yamazaki (1990a, b), we added additional static water pressures on the harmonic dynamic wave pressure, which allowed us to simulate the case with larger water depth. A series of experiments were conducted under numerous different wave and soil conditions, which allowed us to examine the influence of wave and soil parameters on the wave-induced pore pressure as well as liquefaction. The experimental results showed the significant influence of liquefaction on sandy seabed in shallow water.
