چکیده

Liquefaction is a serious natural hazard in susceptible regions that are prone to earthquakes. according to empirical and field studies, insuciency of liquefaction assessment methods in determining liquefaction through clays and high prediction errors has caused an unceasing new development. in this article, a comprehensive history review is presented to organize the literature on the liquefaction potential evaluation published prior to 2017. a deterministic approach based on spt (standard penetration test) records is considered to create an appropriate connection between different methods, facilitate reviewing the development of correlations in the past and current decades, assess both the cyclic stress and the ow liquefaction in a unified system, compile the latest research developments, and identify the main sources as a database for the future investigators. the study attempts to assess cyclic stress method (1971) and chinese criteria (1982) in evaluating the liquefaction potential and to discuss the insuciencies of these methods with reference to the liquefactions caused by the chi-chi (taiwan) and adapazari (turkey) earthquakes in 1999. besides, the absence of soil improvement on the basis of vulnerability and performance is identified as a research gap in this study.
