Abstract

Soil liquefaction is one of the complex topics in geotechnical engineering, and a variety of liquefaction studies have been reported, including the hyperbolic function (HBF) method for calculating the liquefaction factor of safety. This research aims to assess its performance, quantitatively, in terms of accuracy, recall, precision, etc. To achieve the objective, a new soil liquefaction database with the data from published papers was also compiled. Based on a total of 796 soil liquefaction case histories, the study shows that the accuracy of the HBF method is about 92%. In addition, the findings from this research also include: (i) the accuracy of the HBF method is comparable with other well-known methods (also SPT-based) for computing the liquefaction factor of safety; and (ii) the HBF method mainly developed with the data from Taiwan is applicable to other regions, given its accuracy still above 90% based on the data outside Taiwan.
