タイトル（英）：	INFLUENCE OF LIQUEFACTION ON SEISMIC GROUND MOTION AT LIQUEFIED SITE IN SAKAI - MINATO
抄録（英）：	An earthquake ground motion record was obtained at a reclaimed land with widespread liquefaction in Sakai-Minatoduringthe 2000 Western Tottori earthquake. In this paper, simulations by an effective and a total stress analyses using program FLIP is carried out, which provides us an evaluation of input motion at the base of the record site. Further, an influence of liquefaction on seismic ground behavior at the site is discussed through the simulation above-mentioned. The effective stress analysis result with another acceleration record obtained at a hard soil site near the reclaimed site multiplied by 1.5 to 2.0 as an input motion provides a good agreement with the observed motion. The result of the analysis also shows that thin surface layer with silty fine sand might reach an initial liquefaction stage, harmonizing the situation associated with liquefaction of the surrounding ground.
