1. Introduction. “Soil” – “rock”. Characteristics of rocks and rock massifs. Field investigations.
2. Physical properties of rocks.
3. Non-destructive methods – ultrasonic investigations.
4. Destructive methods. Types of strength investigations. Uni-axial stress: strength to uni-axial stress and Young’s modulus. Uni-axial stretching (Brazilian method) – strength to stretching.
5. Integrity. Characteristics of weathering processes and degradation mechanisms in rocks. Description of methods modelling long-term destructive processes.
6. Classification of rock massifs (Bieniawski – RMR, Barton – Q, Hoek – GSI).
7. Destruction criteria: Coulomb-Mohr failure criterion, Hoek-Brown criterion and generalized Hoek-Diederichs formula.
8. Based on the Hoek-Brown criterion, determination of rock massif parameters (mb, s and a), rock massif deformation modulus and Coulomb-Mohr parameters (c and ).
9. Parametric analysis of the changes in stress distribution in rock massifs during construction of excavation using the finite-elements method.
10. Determining the influence of tunnel geometry on stress distribution and visualization of stress distribution around excavation.
Type of course
On completion of the course, the student:
- makes assessment of a rock massif,
- calculates the physical parameters of rocks,
- calculates the strength to uni-axial stress and Young’s modulus,
- interprets the degree of degradation of rocks,
- determines integrity and calculates the changes,
- understands deterioration mechanisms and describes them using a mathematical apparatus.
Final written assessment.
