摘　　要：根据地震液化理论和前人对地震液化调查的研究成果,对《建筑抗震设计规范》等规范中地震液化判别公式存在的标贯点埋深对液化的影响问题进行了分析和讨论;指出了判别公式中临界击数(Ncr)与标贯点埋深(ds)成线性增大的关系与工程实际不符,并结合工程实例加以验证,对工程实践具有指导意义。According to the research on the theory and investigation achievement of earthquake liquefaction, analyses and discussion on the problem about the relation of Ncr and d_s in the decisive equation of ground liquefaction of the anti-seismic codes are carried out, and herein that proved by practical examples. The conclusions are helpful for engineering practice.
