This paper outlines a procedure for evaluating
liquefaction resistance of soils using shear wave
velocity measurements. The procedure follows the general
format of the Seed-Idriss simplified procedure based on
SPT blow count. It was developed following suggestions
from industry, researchers, and practitioners, and using
case history data from 26 earthquakes and over 70
measurement sites in soils ranging from sand to sandy
gravel with cobbles to profiles including silty clay
layers. The procedure correctly predicts moderate to
high liquefaction potential for over 95% of the
liquefaction case histories. A case study is provided to
illustrate the application of the proposed procedure.
