Course contents

Requirements/Prior knowledge

A prior knowledge and understanding of Continuum Mechanics, Hydraulics, Soil Mechanics and Applied Geology is required to attend with profit this course.

This knowledge is typically acquired during the following undergraduate courses: Structural Mechanics, Hydraulics, Geotechnics, Geology and Applied Geology.

Fluent spoken and written Italian is a necessary pre-requisite: all lectures and tutorials, and all study material will be in Italian.

PROGRAM

Geotechnical characterisation of rock-masses (18 hours). Geotechnical description and classification of rock material. Joint properties. Stereographic nets. Strength, deformability and permeability properties of rocks, discontinuities and rock-masses. Rock-mass classification systems.

Calculation and design methods (2 hours). Limit equilibrium method. The new “Norme Tecniche per le Costruzioni” (chapters 2 and 6).

Underground constructions (2 hours). Stability of room and pillars mines.

Rock slope stability (14 hours). Planar slope stability. Influence of hydraulic conditions. Stability of 3D rock wedges. Rockfall. Toppling. Stabilisation measures. Monitoring.

Exercises (16 hours)

Teaching methods

Class lessons, class and home exercises

Assessment methods

Oral examination with exercise revision.

During the oral exam the student has to answer to 4 questions on the following points:

question on one of the first 5 exercises
question on the theoretical aspects covering the first part of the course dedicated to base Rock Mechanics concepts
question on one of the last 5 exercises
question on the theoretical aspects covering the second part of the course dedicated to applications in Rock Mechanics

Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents. To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, some ability for critical application, and a comprehensible use of technical language. A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, inappropriate use of language, and/or logic failures in the analysis of the subject.
