Abstract
ABSTRACT The oscillatory pore pressure excited in porous seabed by ocean waves is theoretically and experimentally examined in the context of the wave-induced liquefaction. A govering equation on the oscillatory pore pressure is presented and verified with the model tests. The comparisons of the finite difference solutions with the measurement of the oscillatory pore pressure have shown a good agreement. The governing equation is also adopted to estimate the liquefaction potential of the model seabed and its applicability is confirmed. It is shown that the wave- induced liquefaction is a kind of quick sand caused by the upward seepage force induced repeatedly in the seabed by ocean waves.
