Introduction to Geomechanics 1300-OWGMW

1. Basic concepts. Stress field rules, including stresses in the earth's crust.
2. Review of basic knowledge on rocks, rock massifs with respect to studies of tectonophysics and in a determination of paleostress.
3. Geomechanical assessment of rock massif (rock mass properties). Engineering facilities implemented in rock massifs, rock massif stability problems. Rock massifs as underground storage of waste and resources.
4. Types of stress in the Earth's crust, relative stress magnitudes, Anderson's classification scheme, stress magnitudes at depth. Measuring in situ stress, in the laboratory as well by geologic stress indicators.
5. Ultrasonic nondestructive tests, study methods and measurement of longitudinal, shear and surface wave velocity.
6. Behavior of rocks under variable load and deformation conditions (impact of confining pressure, temperature, pore fluids and time).
7. Stress and deformation parameters.
8. Models of rock behavior in critical states, equilibrium conditions in a triaxial stress state.
9. Deformation mechanisms, failure models and ways to counteract them.
10. The stress-strain criteria in a determination of deformation phases; the pre- and postcritical states of deformation manifested in propagation of elastic waves and correlation with acoustic emission.
