Overview

Enhanced In-Situ Geotechnical Testing

Course Description

This course provides an overview on the types of in-situ geotechnical tests and geophysical methods. Special emphasis is placed on the utilization of the expedient seismic cone penetration testing (SCPTu) for efficient collection of site-specific data for geotechnical investigations. Perform up to five independent readings on soil response and review interpretative methods for obtaining a suite of soil parameters and properties often required in geotechnical analyses, especially numerical modeling simulations. Gain hands-on experience and evaluate numerous case studies, which are interwoven throughout the course to show the general applicability of the approaches in soil behavior, as well as direct applications to full-scale foundation response.
