摘　　要：地震时土体液化是港口建筑物及其他建筑物破坏的主要原因之一,所以在结构抗震设计规范中都有地基土液化判别的方法。但由于土液化的复杂性,不同国家的研究者对液化认识的不同,不同国家规定的液化判别方法也不同。对我国、日本、美国、欧洲等国家抗震设计规范中地基液化的判别方法及考虑的因素进行了分析对比,并给出了一个对比分析实例。Experience demonstrates that one of the most significant sources of earthquake damage to port facilities is sand liquefaction, as a result of which liquefaction identifying method of ground soil has been involved in seismic design code worldwide. Different methods exist in various design codes due to complexity of earthquake- induced liquefaction. In this paper, comparative study on identifying method with considerations of corresponding influences in seismic design guidelines of different areas is analyzed by evaluating liquefaction in engineering practice.
