Overall objective

Apply continuum mechanics to soils and rocks in order to describe and model their (hydro-)mechanical behavior under the effect of natural or anthropogenic activities.

Course content and organisation

This course covers the study of the response of soil and subsoil constituents used as materials or supports for structures (mines and quarries, tunnels, buildings, etc.), to enable their exploitation or development.

Contents:
- Reminder of continuum mechanics
- Characterization of soil and rock behavior in the laboratory
- Stresses and strains induced by underground structures
- Water in soils and rocks (hydrostatics, effective stresses, hydrodynamics)
- Soil settlement and swelling
- Fractured rock masses: geometry and mechanical behavior
- Stability of unconsolidated slopes and fractured rock slopes


At the end of this course, students will master the fundamentals of soil and rock mechanics, and be able to use them to analyze or predict their behavior, and to carry out simple settlement and stability calculations and pre-sizing of surface or sub-surface structures such as tunnels, cuts and embankments. Applications include civil engineering (public works), extractive industries (mining, oil, quarrying, etc.) and natural hazards (landslides).


Particular attention is paid to the intellectual approach required to provide quantitative answers to concrete problems where data is complex, incomplete or uncertain.

Skills

Levels Description and operational verbs
Know Know the basic quantities of continuum mechanics (stresses, strains) and the relationships that link them to each other (Hooke's law) or limit them (fracture criteria). Know the methods for describing the geometry of fractured rock masses and their mechanical behavior. Know the the methods used to characterize the mechanical behavior of soils.
UnderstandUnderstand the difficulties inherent in applying continuum mechanics to geomaterials. Understand how the presence of discontinuities (fractures, faults, etc.) modifies the (hydro-)mechanical behavior of a rock mass, making it different from that of a laboratory specimen. Understand the fundamental role of water in soils.
Apply  Effectively apply continuum mechanics to describe the behavior of geomaterials. Apply this knowledge to the analysis of rock blocks stability (rockfalls), the quantification of soil compaction and the analysis of slope stability in soft ground (landslides).
Analyse 

Analyze in detail the mechanical consequences of creating a void (gallery, tunnel, etc.) in an initially loaded medium. Analyze the specific (hydro-)mechanical behavior of fractured rock massifs, compared with that of soils, and vice versa.
