Abstract
A new liquefaction prediction and assessment method considering the randomness of waveforms and duration of seismic motions has been developed. The validity of the proposed method was clarified in light of the past five case histories involving the Central Japan Sea Earthquake, the Kushiro offshore Earthquake, the Southern Hyogo prefecture Earthquake, the Suruga Bay Earthquake, and the 2011 off the Pacific coast of Tohoku Earthquake, Japan. The results demonstrate that the proposed method has improved the capability of the liquefaction prediction and assessment, thus warranting its wider applications to disaster mitigation at port and coastal area.
