摘　　要：近年来,可液化场地桩-土-桥梁结构互作用问题一直是理论研究的热点。首先回顾了国内外破坏性地震中由于场地液化造成的桩基震害现象及其损伤破坏机理;然后梳理了国内外学者在液化场地桩-土相互作用领域开展的数值模拟、实验研究,系统总结了两种典型数值模拟方法、三类实验研究方法,并对其优劣进行了初步分析;最后,分析了现有研究存在的不足,提出了亟待解决的相关问题,给出了研究建议。研究成果可为该领域研究人员提供基础性借鉴。The problems of pile-soil-bridge interaction always are a hot spot in theoretical research in recent years.First,earthquake damage phenomenon and the damage failure mechanism of pile foundation in liquefaction site were summarized.After that,two typical numerical simulation methods and three kinds of experimental research methods in pile-soil interaction in liquefaction site which of both here and abroad were summarized.The contributions made by scholars at home and abroad in the field of pile-soil interaction in liquefaction sites were also summrized.Finally,the shortcomings of existing research were analyzed and the unsolved related problems were putforward and some suggestions for the research were proposed.The results can provide some reference for the relevant researchers.
