Enhanced In-Situ Testing for Geotechnical Analyses and Foundation Design

Course Description

The course provides an overview on the types of in-situ geotechnical tests (SPT, CPT, CPTu, DMT, PMT, VST) and geophysical methods (Refraction, CHT, DHT, SASW), and places special emphasis on the utilization of the expedient SCPTu (and related SDMTa) for efficient collection of site-specific data for geotechnical investigations. Up to five independent readings on soil response are collected in a single sounding, particularly the tip stress, sleeve friction, porewater pressure, time dissipations and downhole shear wave velocity. Interpretative methods are reviewed for obtaining a suite of soil parameters and properties often required in geotechnical analyses, especially numerical modelling simulations. The usefulness of the small-strain shear modulus (Gmax), obtained from field shear wave measurements, is documented as an initial state parameter, representing the beginning of all stress-strain-strength curves (drained, undrained, static and dynamic). Numerous case studies are interwoven to show the general applicability of the approaches in soil behavior, as well as direct applications to full-scale foundation response.
