After successful completion of the course, students are able to...

• name the differences between soil and rock mechanics,
• explain the differences between rock and rock mass,
• describe suitable exploration measures for different building projects in rock mass,
• discuss different concepts of rock mass classification,
• discuss rock mechanical characteristics and appropriate laboratory and field tests,
• quote methods for tunnel and tunnel design and to outline the basics of rock mass behavior-analysis based on the perforated disk,
• distinguish between different tunneling methods,
• list the basic principles of the new Austrian tunneling method (NATM), 
• outline the load transfer of foundations in rock masses,
• give an overview of the common anchor types and to explain the functioning of different anchor types in soil and rock,
• solve simple numerical examples related to rock mechanics and slope stability.

The course covers the following topics:

• Rock mechanics
• Rock engineering
• Tunneling

An introduction to the basic concepts of rock mechanics will be given, exploring the importance of distinguishing between rock and rock mass. Essential laboratory tests and field tests to determine parameters of rock mechanics are explained. Different methods for rock mass classification, which are influenced by these parameters are presented. 

Various options for the calculation of tunnel structures, possibilities for assessing the slope-stability in rock engineering and the concept of the ‘observational method’ used in Austria are explained. Furthermore, the principle of operation for different types of anchors is discussed and state of the art construction methods for both slopes in rock masses and tunnels are outlined. 

Introduction to basics of rock mechanics and rock mechanics related issues. Rock mass classification systems and options for the calculation of tunnel structures and specific failure mechanisms of slopes in rock engineering are discussed. Common construction methods for tunnels and slopes in rock masses are presented. Simple numeric examples can be solved with the knowledge provided in this lecture.
