Investigation: Geotechnical Investigations

This module teaches the basics of geotechnical investigations for civil engineering purposes. The described subsoil investigation by indirect (e.g., drilling methods) and direct exploration methods (e.g., dynamic sounding) form the basis for an understanding of a civil engineering description and evaluation of soil and rock.

After completing this module, you will have a sound knowledge of:

• The objective of a geotechnical investigation;
• The purpose of structural and subsoil investigation by means of excavations;
• Differentiation between direct and indirect excavation methods, such as drilling methods and indirect excavation methods, such as dynamic sounding.
