地震引起的土壤液化是造成全世界范围内重大地震灾害的主要原因之一。这是岩土地震工程界长期关注的一个复杂现象。土壤液化评估是工程实践中不可或缺的一项工作。本文概述了过去 50 年土壤液化评价方法研究的发展和演变，重点在于从确定性方法和概率法分析的角度回顾土壤液化评估的简化方法所取得的最新进展。最近 20 年里，这些简化方法在两个方面取得了新的进展：(1)现场液化调查数据库的案例数量和质量提升，现场案例由一种或多种原位测试(如标准贯入试验，静力触探试验，剪切波速测试，和动力触探试验)进行描述；(2)各种不确定性的认识和概率评价方法的发展。通过对这些进展的回顾，提供了一些见解；并对循环应力比和液化强度计算的几个不确定性校正因素进行了讨论；对几种有代表性的液化评价方法进行了比较，并讨论了液化评价中遇到的共性问题。通过对数十年来土壤液化评估的研究、发展和实践经验的总结，为下一代土壤液化评估方法提供了前景。
Earthquake-induced soil liquefaction is one of the leading causes of significant earthquake damage worldwide. It is also a complicated phenomenon of long-standing interest in the geotechnical earthquake engineering community. Assessment of soil liquefaction potential is an essential task in engineering practice. This paper provides an overview of the development and evolution of the procedures for evaluating soil liquefaction triggering during the last five decades. The focus here is on the more recent advances in the simplified procedures for soil liquefaction potential evaluation from both deterministic and probabilistic analysis perspectives. Over the past two decades，these simplified procedures have been advanced，especially in two aspects：(1)advance in both quantity and quality of the databases of case histories，in which sites were characterized by one or more in situ tests(such as the standard penetration test，the cone penetration test，the shear-wave velocity measurement，and the dynamic cone penetration test)，and(2)recognition of various uncertainties and development of probabilistic evaluation procedures. Insights are provided herein through a critical review of these advances. Discussions are also extended to a few correction factors that relate to the cyclic stress ratio and the cyclic resistance ratio in situ tests under a set of reference conditions. Cross-comparisons are made among selected representative methods of liquefaction potential evaluation，and issues encountered in these evaluations are discussed. Lessons learned from decades of research，development，and practice of soil liquefaction potential evaluations，as summarized in this retrospective review，offer a prospect for next-generation liquefaction triggering evaluation procedures.
