Engineering Geological Characterization and Mapping

Objectives

Students should dominate several field and laboratory techniques of geotechnical exploration, their benefits and limitations, since they are as important for geological engineers as the knowledge of analysis and design using the parameters obtained from field/laboratory tests.

Besides, they will also gather sufficient knowledge on the application of parameters in the framework of assessing an engineering geological zonation of the ground. So, it is intended that students must acquire the skills that allow them to develop engineering geological or geoenvironmental mapping studies for supporting site studies of civil engineering design, risk analysis and regional and urban planning

Prerequisites

No special requirements, but the previous knowlege of mechanical exploration techniques, and of soil mechanics and engineering geology classes are advisable.

The presence of the students on, at least, two thirds of the classes is required, unless they are registered under a special status.

Teaching method

Theoretical classes with audiovisual media support (powerpoint) that students can access from the Clip platform. Students must check the references provided for additional information. Practical classes which include the observation of several methodologies of engineering geological mapping, solving problems involving data took from different in situ tests and engineering geological field mapping.

Evaluation method

Continuous evaluation by two tests (respectively 30% + 45% of the final grade) and one final report about field mapping (25%).
