A Comparative Analysis of 2-D MASW Shear Wave Velocity Profiling Technique

Abstract

Multi-channel surface wave data were acquired along near-linear traverses at four separate test sites in southeast Missouri. Each of the acquired surface wave data sets were processed using multichannel analysis of surface wave (MASW) software and transformed into 2-D MASW shear-wave velocity profiles. Shear-wave velocity control extends from the surface to sub-bedrock depths. the interpreted 2-D MASW shear wave velocity profiles were compared to available crosshole seismic and seismic cone penetrometer shear wave velocity data, and to borehole (depth to bedrock) and cone penetrometer control provided by the Missouri Department of Transportation. the 2-D MASW profiles correlate very well with available geotechnical and subsurface velocity control, supporting the conclusion that the MASW technique can be used to generate reliable and interpretable 2-D shear-wave velocity profiles of the shallow subsurface.
