The investigation of liquefaction‐induced ground failures during the Kanto earthquake in Tokyo lowland shows that the sandy desposits containing only a small amount of fines were more prone to liquefy rather than those containing considerable amount of fines. The undrained cyclic strength on undisturbed specimens containing fines is considerably strong in sprite of small SPT N‐values. The formula estimating liquefaction strength proposed herein is formed not only with SRT N‐values, effective overburden pressure and mean diameter, but also with fines contents and confining stress. The grounds which consist of liquefiable sandy deposits within surface layer are generally likely to induce severe ground failures. So a criterion of liquefaction susceptibility with FL values of surface layers is proposed herein in order to estimate liquefaction potential for wide area. A ccording to the comparison between the liquefaction analysis for boring records in actually loquefied sites and unlique キーワード（英）： - 記事区分： - 区分 　　　　論文集
