The objective of this course is to give the students basic knowledge with respect to rock engineering design, including the determination of: (1) intact rock and rock mass mechanical properties, (2) rock mass strength, (3) stresses and deformations around excavations and (4) different types of failure mechanisms. After the course the students shall be able to:

  • Understand the fundamental differences between the rock mass and other types of man-made construction materials.
  • Identify various geological hazards.
  • Use different rock mass classifications systems.
  • Determine the mechanical properties of intact rock and rock masses.
  • Calculate stresses and deformations around underground openings.
  • Understand and calculate the interaction between the rock mass and the installed support.
  • Analyse typical stability problems in rock for tunneling, slopes and foundations.

Content and learning outcomes

Course disposition

The course is conducted on campus and contains lectures on rock mechanical theory, as well as workshops in which the theory is trained in calculation exercises. Much of the work is conducted in smaller groups. The course includes a mandatory laboration and a site visit.

Course contents

  • Basic terms in engineering geology and rock mechanics
  • Geological uncertainties and ground behavior
  • Pre-investigation methods
  • Mechanical properties of the rock mass
  • Rock support
  • Interaction between rock mass and rock support in tunnel engineering
  • Block and arching stability in tunnels
  • Slope stability
  • Foundations on rock

Intended learning outcomes

After the course the students shall be able to:

  • Account for the fundamental differences between the rock mass and other types of man-made construction materials.
  • Describe ground behavior for different geological conditions and identify common geological uncertainties.
  • Use different rock mass classification systems such as the Q system, the Rock Mass Rating (RMR) and the Geological Strength Index (GSI).
  • Determine the mechanical properties of intact rock, joints, and rock masses to be used as input to the rock mechanical calculations.
  • Calculate radial and tangential stresses and deformations around underground openings.
  • Analyze the interaction between the rock mass and the installed support in tunnels with the ground reaction curve concept.
  • Analyze typical stability problems in rock engineering such as block stability, arching stability and slope stability.
