ABSTRACT
Soil liquefaction is the decrease in the shear strength of the soil due to the reduction of the effective stress due
to the increase in the pore water pressure in the ground due to sudden and rapid loading. The purpose of this
study is to compare and evaluate the current situation of the Standard Penetration Test (SPT) based soil
liquefaction analysis methods, which were rather deterministic approaches. In this context, many soil
liquefaction analyses were carried out using several reliable SPT data and the related geotechnical parameters
needed. The well-recognized SPT-based liquefaction analysis methods developed up so far, such as Seed and
Idriss (1971), Tokimatsu and Yoshimi (1983), Japanese Bridge Code (1990), Youd and Idriss (2001), and Idriss
and Boulanger (2014) were compared with each based on the analysis results gathered. Although there were
specific differences between the SPT-based soil liquefaction analysis methods utilized in this research, it was
seen that these differences were of low order, and the studies were instead concentrated on or around the
parametric expressions based on empirical studies, not to compensate for the deficiencies of exceptional cases
in soil liquefaction analysis.
