摘要：

The liquefaction potential index (LPI) has been extensively applied to ground liquefaction hazard assessments. In this paper, the Robertson's unified cone penetration test (CPT) based method was applied to determine the LPIs for case histories in two well-documented investigation areas: Adapazari in Turkey and Yuanlin City in Taiwan. A statistical method was applied to find LPI threshold values for low, medium, and high ground liquefaction potential at LPIs of 5.6, 12.5, and 21.7, respectively. According to an analysis of the various risk levels by applying Bayes' theorem of conditional probability, the probabilities of liquefaction are 0, 32.3, 85.2, and 100% at the low, medium, high, and extremely high ground liquefaction risk level, respectively.
