Near Surface Case Studies

Fundamentals of Active & Passive Surface Wave Testing

Researcher: Brady R. Cox, Ph.D., P.E. Department of Civil and Environmental Engineering Utah State University

Researcher: Joseph P. Vantassel, Ph.D. Department of Civil and Environmental Engineering Virginia Tech

This case study and training course explores modern MASW and passive surface wave testing methods used for geotechnical engineering, seismic site characterization, and subsurface analysis. Topics include active-source MASW acquisition, passive-wavefield testing, uncertainty quantification, dispersion analysis, and practical field setup recommendations for near-surface seismic investigations.

Multi-channel Analysis of Surface Waves

Researcher: Brian B. Herridge

This case study presentation demonstrates how MASW (Multichannel Analysis of Surface Waves) is used for geotechnical engineering, seismic site characterization, infrastructure evaluation, and subsurface strength profiling. Applications include bedrock mapping, pavement evaluation, void detection, bridge and tunnel investigations, crane path safety analysis, concrete inspection, and foundation stability studies using non-invasive seismic methods.
