摘　　要：应用模糊数学,研究饱和砂土地震液化的主要因素,通过建立隶属函数、模糊矩阵和权重向量,得出液化评定指标及其等级划分,并通过工程实例说明。同时,以文中计算成果与现行规范计算成果进行对比,得到一致的判定。This paper uses the fuzzy mathematics to research the main factors of the liquifaction characteristics of the saturated sand by earthquake.It obtains the synthetic judge target and grade of the liquifaction through building membership function,fuzzy matrix and weighing vector.This method is interpreted futher through engineering example.At same time,Its calculation is consistent with calculation of the method in current design code.
