The course wants to provide the students with basic elements of rock mechanics describing the mechanical behaviour and presenting the empirical, experimental and analytical method for the geotechnical characterization of the rock masses.
The problems that the course will deal with are stability of excavations and natural slopes, design of underground openings and stability of foundation in rocks. The course will contains application example and exercises

Mechanical behaviour of rocks: definition of rock mass, rock matrix and discontinues; quantitative description of discontinuity; shear strength of discontinuity and intact rock; rock mass classification methods; empirical method for the characterization of rock mass; field tests for the characterization of rock masses; water flow in fractures rock (field tests); numerical methods for rock mass description.

Excavation and foundation engineering: application of stereographic projection for the analysis of rock kinematics; limit equilibrium methods for the verification of stability of excavation ; rock retaining and reinforcing structures and their design; few cases history of open pitt mines, interesting civil structures and foundation in rocks.

Tunnelling and wide underground openings: surficial and deep tunnels; numerical and analytical methods for the calculation of tunnel support; empirical method for the choices of the construction methodology and of the support type for tunnels; analytical solution for the determination of stress and strain in the surroundings of underground openings; traditional excavation methods (explosives) and mechanised excavation methods (TBM); monitoring method for tunnels during their excavation; application of DEM for the design of tunnels and wide underground openings; application of FEM for the design of tunnels and wide underground openings.

Attività d'esercitazione
Graphical representation of discontinuities geostructural survey, monoaxials compressive tests, triassials tests, direct shear test along discontinuities; state of stress and strain, planar sliding, rock masses, state of stress in the surroundings of a tunnel.

Modalità d'esame
The exams will consist of an oral interview
