摘　　要：本文用Biot固结方程提出了地震作用下地基沉降的计算方法。为检验本方法的有效性 ,将计算结果与 1987年日本Miyagioki地震中在Sendai现场的观测值进行比较 ,两者具有较好的吻合性。This paper presents an analytical method for calculation of the earthquake-induced settlemint of foundation by using Biots type consolidation eguation. In order to investigate the effctiveness of the proposed method, a comparison, of the numerical result with obseved earthquake?induced settlement on the site at Sendai in Japan caused by the Miyagioki earthquake in 1987 are carried out, which shows both of them coincide closely to each other.
