摘　　要：用二维非线性有限元动力分析法研究日本阪神地震中神户人工岛地震液化及预建新机场液化可能性，计算结果与人工岛实测资料进行验证，提出海床冲积砂层液化及人工岛基础冲积砂层趋向液化观点，计算结果也表明，相同地震作用下，新机场也发生液化．In this paper, two dimensional FEM is used to study the liquefaction of the artificial island in Kobe during Hanshin earthquake and the liquefaction possibility of the designed airport. The analytical result is compared with the observation data obtained from the island . The viewpoint of liquefaction of the alluvial sand on the seabed and the liquefaction tendency of the alluvial sand on the island foundation is presented. The calculation result also shows that liquefaction will occur at the airport under the same earthquake .
