The second part of the course focuses instead on the analysis of groundwater movement describing the procedures for geo-hydrological characterisation and the relevant methods for engineering design. AIMS AND CONTENT LEARNING OUTCOMES To introduce the principles of rock mechanics and rock testing at the laboratory and field scale To demonstrate the relevance of rock mechanics to the study of boundary value problems To present some of the methods for the engineering analysis of groundwater flow To apply some of the existing groundwater flow models to the study of geotechnical problems AIMS AND LEARNING OUTCOMES Understanding the models that describe strength and deformation of rocks Recognizing the influence of geological structure on the engineering behaviour of rocks Using mathematical models for the analysis of instabilities in rock masses Applying analytical tools to the prediction of hydro-geological variables Evaluating soil parameters that govern groundwater infiltration Assessing the effects of groundwater abstraction on ground subsidence PREREQUISITES The prerequisites of the course are: a) a good knowledge of solid mechanics and b) a sound understanding of the principles of geotechnical engineering including both mechanical aspects (e.g. laws of soil deformation and strength) and hydraulic aspects (e.g. flow in porous materials under both transient and stationary conditions). TEACHING METHODS The course has an approximate duration of 50 hours. It consists of a combination of theoretical lectures and class exercises. The language of the course is English. SYLLABUS/CONTENT Rock mechanics Geological setting of rock materials Stress and strains in the context of rock engineering Intact rock behaviour Discontinuities and rock masses Rock testing techniques Foundations and slope instability mechanisms in rock masses Rock excavations Rock reinforcement and support Groundwater analysis Definition of groundwater: phreatic aquifers versus artesian aquifers Methods of measuring and estimating groundwater infiltration capacity Transient and steady state processes Dupuit’s theory Steady-state pumping from wells Transient pumping from wells Groundwater and permeability testing Permeability of fractured rocks RECOMMENDED READING/BIBLIOGRAPHY Rock mechanics J.

The written test lasts typically two hours and includes between two and four questions, whose weight is equally split between the subjects of rock mechanics and geo-hydrology. The oral presentation lasts about half hour and is followed by questions posed by peers and lecturer. The subject of the oral presentation is free but it must cover an engineering case study relevant to the domain of rock mechanics and/or groundwater analysis. ASSESSMENT METHODS The written test and the oral presentation have the purpose of evaluating the student's learning outcomes in different contexts. The written test enables the students to demonstrate their knowledge in a context that favours reflective reasoning on blind questions. The presentation allows the students to demonstrate their knowledge in a context that privileges communication and dialectical interaction skills. The written test has a weight between 80% and 90% of the final grade of the exam. The individual oral presentation is evaluated collectively by the students and the lecturer. It weighs between 20% and 10% of the final grade of the exam.
