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.

Subject matter

Engineering Geological Mapping (EGM): Origin, evolution and contents; geotechnical and lithogenetic units. Classification; examples of methodologies and related information. IAEG approvals. 2.5D and 3D EGM. Geotechnical Zoning (GZ). Practical application to field studies.

Geotechnical characterization. Field tests versus lab tests. Characterization of sandy soil and clay soils. Weathering profiles. Field mechanical characterization: SPT (correction factors and correlations) and other dynamic penetrometers (DPL; DPH, DPSH). Equipments, test conduction, results and correlation factors of Static penetration cone test (CPT, CPTu / piezocone, SCPTu), Vane shear test (VST), Pressuremeter test (PMT) and Plate bearing test (PLT).

Main lab tests for soils with standards application.
