Abstract:

This paper presents preliminary guidelines for assessing the liquefaction resistance of soils using small-strain shear wave velocity. The guidelines are based on field performance data from 17 earthquakes and in situ shear wave velocity measurements at over 40 different sites in soils ranging from sandy gravel with cobbles to profiles including silty clay layers. Additional data are needed from denser soil sites shaken by stronger ground motions to further validate the proposed liquefaction potential boundaries.
