In this paper, results of Standard Penetration Test (SPT) and shear wave
velocity (Vs) measurements have been compared for liquefaction potential evaluation
in south of Tehran in Iran. Liquefaction potential by SPT was evaluated based on the
simplified procedure of Seed and Idriss [1-2] and specifications for highway bridges
[3] for sandy soils and silty soils respectively. On the other hand, the liquefaction
potential assessed using the Vs measurements based on the method proposed by
National Institute of Standards and Technology (NIST) in 1998 [4]. In this study, 118
borehole data were studied considering the soil type and ground water level. Vs data
was obtained based on 9 downhole and 75 seismic refraction tests performed by the
International Institute of Earthquake Engineering and Seismology (IIEES) [5]. The
safety factor at different depths and liquefaction Potential Index at different
boreholes was compared. Generally, results of the two methods are in agreement,
especially if the soil is considered to be cemented.
