EXPERIMENTAL ANALYSIS OF WAVE-INDUCED LIQUEFACTION IN A FINE SANDBED

Kojiro Suzuki, Shigeo Takahashi, Yoon-Koo Kang

Abstract


A series of experiments were conducted to examine wave-induced liquefaction in a loosely packed fine sandbed, which was specifically used to ensure the presence of residual excess pore pressure. Also observed was the compaction of a liquefied sandbed in response to cyclic wave loading; a phenomenon thought to reduce the possibility of liquefaction. In addition, pore water was supplied from the bottom of the sandbed such that the effect of underground water pressure on liquefaction could be clarified.
