SEMI-EMPIRICAL PROCEDURES FOR EVALUATING
LIQUEFACTION POTENTIAL DURING EARTHQUAKES

Abstract—Semi-empirical procedures for evaluating the
liquefaction potential of saturated cohesionless soils during
earthquakes are re-examined and revised relations for use in
practice are recommended. The stress reduction factor
􀀋rd 􀀌 , earthquake magnitude scaling factor for cyclic stress
ratios ( MSF ), overburden correction factor for cyclic stress
ratios ( K􀁖 ), and the overburden normalization factor for
penetration resistances ( CN ) are discussed and recently
modified relations are presented. These modified relations
are used in re-evaluations of the SPT and CPT case history
databases. Based on these re-evaluations, revised SPT- and
CPT-based liquefaction correlations are recommended for
use in practice. In addition, shear wave velocity based
procedures and the approaches used to evaluate the cyclic
loading behavior of plastic fine-grained soils are discussed.
