The course represents a link between the rock mechanics fundamentals and the rock engineering application. The course is based on the characterisation of rock materials and masses and on the solution of some typical conditions for surface-underground excavations, while the monitoring of natural - artificial structures is presented as a part of the design methodology in geomechanics. The content of the lessons represents a useful basis for other engineering oriented courses such as Tunnelling, Rock and soil reinforcing, Mining methods, Underground excavations, Landslides and slope stability.

The student will be able to define and obtain the main geomechanical properties of a rock material and of a rock mass as well. These elements contribute to understand the behavior of rock masses and materials: behaviour and technology are fundamental for the solution of the practical problems in the geoengineering field, aspect that is also developed in the course. The main competence for the student will therefore be related to stability assessment in the excavation engineering problems.

The presentations of the lessons are loaded on the website and they follow the program. Class notes taken directly during lessons are fundamental for the student.
Reference textbooks are presented (and available in the DIATI library) for details. Among the others:
Hoek E. Practical Rock Engineering, Rocscience;
Brady B.H.G. Brown E.T. Rock Mechanics for Underground Mining.
The presentations of the various lessons are loaded on the website and they follow the program; they can be downloaded for free.

Links to scientific boards websites are uploaded on the Portale della Didattica for continuous and updated knowledge .
Modalità di esame: Prova orale obbligatoria; Prova scritta su carta con videosorveglianza dei docenti;
The exam follows modes a) and b) as indicated by Politecnico for online exams.
The exam is oral, with about 3 questions regarding all the program of the course. In addition there will be a written exercise, live, regarding the stress- strain analysis of rock materials, the limite equilibrium method and the geostructural projections. Timing about 30-40 min.
Each part is contributing to the final score in the same way (final vote from 18/30 to 30/30 +L).
Self verifications carried out during the course will help the students to understand the questions.
Exam: Compulsory oral exam; Paper-based written test with video surveillance of the teaching staff;
The online exam is oral, as indicated by Politecnico for this option of exams.
Objective of the exam: this exam is intended to evaluate the ability of the student to solve analytic exercises in geomechanics, and to evaluate the knowledge in theoretical background. The reference by the student to practical examples is also appreciated, considering that this is an engineering course!
No didactical material can be used during this exam.
At the beginning of the exam there will be a written exercise, to be solved live, regarding the stress- strain analysis of rock materials, the limite equilibrium method and the geostructural projections. Then the oral questions (2-3) regarding all the program of the course: for example a question on failure criteria, on rock mass classification, on the redistribution of stresses around an underground opening, monitoring issues, excavation for mining purposes.
Timing about 30-40 min.
Each part is contributing to the final score in the same way and proportion. Final mark range is from 18/30, which is obviously the minimum to pass the exam, to 30/30 +L.
Self verifications proposed and carried out during the course session will help the students to understand the questions and appreciated.
