517 A Practical Guide to Geophysics for Geotechnical Site Investigation
Traditionally, geotechnical site investigation methods have relied heavily upon physical measurements of the ground through trenching, coring, and sampling. These methods are well-established and invaluable for the information they provide on composition, structure, and stability. However, precise analysis is limited to the region immediately surrounding the test location; between these sites, results can only be assumed. More test sites produce more comprehensive analysis, but physical testing can be slow and expensive. The rise of geophysical methods has allowed geologists and engineers to understand what is happening between the physical test locations with more certainty and, in the best situation, actually reduce the number of physical test sites required. This workshop, open to all (students, faculty, and professionals), will look at a selection of geophysical methods suited to site investigation projects and discuss how they work, what they can tell you about the subsurface and how they are implemented. This includes demonstrating how the project aims will dictate survey design and system set-up. The focus will be on seismic, resistivity, and GPR (ground penetrating radar) methods and include geotechnical and environmental case studies. The workshop presentation will be available to take away afterwards.
