Abstract

Shear wave velocity ( V s ) values calculated from Standard Penetration Tests (SPTs) and from multi-channel analysis of surface waves (MASW) are consistent in their prediction of V s . This analysis was based upon SPT and MASW data from 10 localities representing four different depositional environments across North America. Homogeneous deposits tend to produce the closest agreement between MASW- and SPT-derived V s . Poorly sorted deposits can predict less consistent agreement between MASW- and SPT-derived V s . Further, at depths of greater than 20 m below grade, based upon the testing geometry within this work, the prediction of V s between the two methods can differ.
