Title

A 2-D MASW Shear-Wave Velocity Profile along a Test Segment of Interstate I-70, St. Louis, Missouri

Abstract

The University of Missouri-Rolla acquired multi-channel surface wave (Rayleigh wave) seismic data along a 6400 ft segment of Interstate I-70 in downtown St. Louis, Missouri. the acquired surface wave data set was processed [multi-channel analysis of surface waves (MASW)] and transformed into a 2-D MASW shear-wave velocity profile with a station-spacing of 40 ft. the interpreted depth to bedrock along the length of the 2-D profile varies between 20 ft and 44 ft. Geotechnical data provided by the Missouri Department of Transportation and presented herein indicates the interpreted 2-D MASW shear-wave velocity profile correlates well with available bedrock (borehole) and seismic cone penetrometer control, supporting the conclusion that the MASW technique can be used to generate reliable 2-D shear-wave velocity profiles.
