Il corso ha come obbiettivo primario quello di rendere gli studenti in grado di acquisire in situ, mediante tecniche speditive, dati di natura geotecnica, geomeccanica e idrogeologica, nonché di elaborare tali dati al fine di realizzare carte tematiche applicative.

GEOTECHNICAL AND HYDROGEOLOGICAL SURVEY AND LABORATORY The course aims to provide to the student the ability to acquire geotechnical, geomechanical and hydrogeological data, by means of easy in situ and laboratory techniques, and to process such data in order to create thematic applicative maps or produce the dataset for engineering design. The course comprises lectures in which the fundaments of engineering geology are recalled, and the main geotechnical and hydrogeological instruments described, focusing on the practical and executive aspects as well and the data processing methods. Laboratory practical classes and data processing exercises are planned. The course includes field activities: guided or individual field surveys and in situ measurements, followed by a personal geo-technical and hydrogeological report that will be evaluated.
Each topic comprises a description of procedures for data collection and data processing. The main contents are: - geological-technical description of soil, with visual or simple field instruments - geotechnical soil classification (USCS - AASHO) - hydrogeological properties and measurement methods - hydraulic flow measurements - execution and processing of geomechanical surveys for the characterization of rock masses - rock mass classifications (Basic Geological Description (BGD); GSI, RMR (Bieniawski),Q system (Barton), and rock mass strength and deformability - landslides classification, and morphometry - definition of geo-technical units - examples of engineering geological mapping intended to specific cases.
The suggested methods for data collection and processing are presented in accordance with and referring to the existing legislation.
