Abstract

Shear‐wave velocity (Vs) as a function of soil stiffness is an essential parameter in geotechnical characterization of the subsurface. In this study, multichannel analysis of surface wave (MASW) and downhole methods were used to map the shear‐wave velocity‐structure and depth to the bedrock surface at a 125m × 125m geotechnical site in Missouri. The main objective was to assess the suitability of the site for constructing a large, heavy building. The acquired multichannel surface wave data were inverted to provide 1D shear‐wave velocity profile corresponding to each shot gather. These 1D velocity profiles were interpolated and contoured to generate a suite of 2D shear‐wave velocity sections. Integrating the shear‐wave velocity data from the MASW method with the downhole velocity data and the available borehole lithologic information enabled us to map shear‐wave velocity‐structure to a depth on the order of 20m. The bedrock surface, which is dissected by a significant cut‐and‐fill valley, was imaged. The results suggest that the study site will require special consideration prior to construction. The results also demonstrate the successful use of MASW methods, when integrated with downhole velocity measurements and borehole lithologic information, in the characterization of the near surface at the geotechnical sites.
