Geotechnical Studies: Preliminary Investigations

This lecture covers the importance of preliminary geotechnical studies, including cartography, existing geological surveys, and reconnaissance campaigns. It also discusses the depth of investigation required for a project, different types of geotechnical tests, and the significance of hydraulic conditions. The instructor emphasizes the use of various tools such as walk-over surveys, piezometers, and penetration tests to gather essential data for foundation design and construction. Additionally, correlations of soil properties and geological mapping are explored to understand the subsurface conditions better.
