Course Description

• Geology of rocks and the relevant definitions that characterize their properties. Types of rocks. The stress state of the rock. Elastic, plastic behavior, analysis and synthesis of stresses and deformations.
• Landslides and control of rocky slopes. Hoek & Bray method.
• Construction of tunnels and underground works. Vertical and horizontal tunnel opening methods.
• Construction of open vertical tunnels (CUT and COVER). The up-down method. Methods of construction and slope support technics.
• TBM method. Types of drilling machines.
• NATM method, design of temporary support measures with the theory of plastic zones, anchors and bolts, dimensioning of the final supporting ring.
• Theories on the calculation of stresses in tunnel walls.
• Basic empirical rock classification methods for the construction of tunnels: Bieniawski, GSI, Barton. Design of support measures with empirical methods.
