A simplified method termed Seed and Idris’s method is often used by practicing engineers for evaluating the liquefaction potential. However, in the last 3 decades, significant developments have been made in this area. In this paper, standard penetration test (SPT) based three different approaches reported in the literature to evaluate liquefaction potential have been reviewed. The liquefaction potential is analyzed using these approaches for the Roorkee region. The standard penetration test has been conducted at five different locations in the Roorkee region, consisted of recording the number of blows (N) and the collection of soil samples. Based on these data, the liquefaction potential is computed for an earthquake magnitude of 7.0 on the Richter scale and peak ground acceleration of 0.24 g. For these parameters, the safety factor against liquefaction is found out using three different approaches reported in the literature. The results from these three approaches are then compared. Moreover, the study is also carried out for the earthquake magnitude of 6.5 considering the seasonal variation in the groundwater table to show its effects on liquefaction susceptibility. The present study is quite helpful in understanding the development of SPT-based relations for liquefaction study.
