This study examines two recently-developed DMT-based methods, one CRR7.5-KD boundary curve and one CRR7.5-ED boundary curve, for evaluating the liquefaction resistance of soils using in-situ test data. The collected data consist of a number of liquefied and non-liquefied case histories, which were performed shortly after the disastrous Chi-Chi earthquake in 1999. The results of examining the CRR7.5-KD and CRR7.5-ED boundary curves showed that both curves are capable of accurately estimating the liquefaction resistance of soils and thus the liquefaction potential of soils. The developed DMT-based methods therefore have the potential to be an alternative to the existing procedure of liquefaction evaluation, such as the SPT and CPT evaluation methods, to practically obtain a more accurate liquefaction resistance of soils.
