Fast Near-Surface Investigation With Surface-Wave Attributes

Abstract

Summary Fast methods for site characterization and imaging of potentially problematic zones, such as voids and discontinuities, are valuable in geotechnical engineering, to manage risks and meet business objectives. We present a nearly real-time screening tool which uses seismic surface-wave attributes (phase velocity and energy) to produce quantitative indication of lithological variations and other shallow targets. We present the results from an engineering experiment and compare them with a priori information on the site.
