Prerequisites:

The proposed program will also allow students who have not followed the Structural Geology Course to achieve the indicated training objectives. There are therefore no prerequisites, but the integration of additional lecture material can be recommended.

Objectives

The Geomechanical Survey Course provides the necessary knowledge to characterize rock masses using conventional surveying techniques, based on the measurement of geomechanical parameters of rock and discontinuities. In addition, digital terrestrial photogrammetry techniques will be shown that allow the creation of 3D models and the possibility of obtaining a considerable amount of information in safe conditions. On the basis of the acquired data, it will be shown the procedure for the most commonly used rock masse classification systems, useful in the definition of geological hazard and in the evaluation of georisources.

Contents

Geomechanical characterization of rock masses. Geomechanical parameters, rock mass classifications, geomechanical surveys through conventional and digital terrestrial photogrammetry. Practicals.

Extended Syllabus

Criteria and methods of field geomechanical surveys:

- Geomechanical characterization by scanline method:
Fractures and Joints: definitions, general characteristics end relationships with respect to the major structures; geomechanical characterization (Jv/WJd, RQD and unit rock volumes); geomechanical parameters of discontinuities (i.e. orientation, spacing, persistence, roughness.)
Faults: fault rocks and their geomechanical characterization.
- Rock mass characterization and classification:
Quality indexes (RQD by Deere et al. (1967) and seismic indexes);
- Geomechanical classification:
RMR by Bieniawski (1976); Q by Barton et al. (1974); RSR by Wickham et al. (1972); Romana (1985, 1993, 1995); GSI (Hoek et al., 1995).
Significance and uses of quality indexes.
Rock and rock mass strenght criteria:
strenght of intact rock bodies and massive rock masses;
strenght of fractures rocks;
kinematic analysis of rock masses;

Field characterization of outcropping structures:
Geological and structural analysis of the main structures within foreland fold-and-thrust belts;
Geomechanical characterization of structures (faults, folds and thrusts) and of rock masses;

Digital terrestrial photogrammetry techniques will be shown that allow the creation of 3D models and the possibility of obtaining a considerable amount of information in safety conditions.

Teaching Methods

Lectures, class field practicals, geomechanical surveys through conventional and digital terrestrial photogrammetry carried out in the field.

Evaluation methods

Verification of learning:

The assessment consists in a mid-term written test and a final oral exam focused on the entire course program and on the field geomechanical survey report. It will be possible to access the final oral exam with a minimum score of 18/30 in the mid-term written test. The oral exam can increase the score of the mid-term written test up to a maximum of 8 points.

The teacher is available to the students during the hours of receipt or by appointment by e-mail. Tutoring is planned.
