Course Aim
The course will give you an understanding for rock mechanics so you after the course will be able to:
- Judge whether rock slopes and underground constructions are stable and be able to give recommendations how to stabilise an unstable construction.
- Judge whether foundations on rock have enough bearing capacity or not.

To be able to do so, you have to be able to:
- Judge which rock properties that are important for the performance and stability of a rock construction
- Understand the importance of and carry out pre-investigations
- Understand the principles of hemispherical projection and be able to carry out stability analyses using the method
- Suggest optimal shape and orientation of underground cosntructions and optimal excavation sequence with respect to the state of stress and the structural geology
- Understand the different failure mechanisms of rock and be able to judge if failure will occur or not.
- Understand the importance of deformations for different kinds of rock constructions and how this affect the design
- Identify potential failure mechanisms in slopes and judge whether they are critical or not.
- Choose a suitable method/criterion to determine/estimate the deformation and failure behaviour of the rock.

Contents
Introduction -
Rock mechanics pre-investigation and classification -
Structural geology, Geological structures in rock and their significance from a rock mechanics perspective. Mapping of joints. Rock mass classification methods. Hemisperical projection.
Rock stress -
Virgin stresses in the rock mass. Stress measurements. Absolute and effective stresses. Stresses around underground openings. Shallow and deep seated excavations are treated. Mohr stress circles. .
Deformation and failure of rock -
Constitutive laws. Failure mechanisms and failure criteria. Experimental methods to determine deformation and strength parameters. Mohr stress circles and failure criteria.
Analytical analysis -
Deformations and stresses around excavations. Analytical methods are covered. Failure of underground excavations. Failure mechanisms and failure criteria. Overstressed rock.
Design and stability of underground constructions and rock slopes -
Design methodology for underground excavations. Local and global stability. Effects of groundwater and on groundwater. Hemispherical projection methods are used to investigate the risk of fallouts and sliding of wedges and blocks. Theories for plane, wedge, circular and toppling failure of slopes. Hemispherical projection methods are used to identify failure modes. Effects of groundwater and drainage. Design criteria for slopes. Remedial measures.

Realization
The teaching consists of lectures, home assignments, laboratory assignments and a field assignment. The laboratory lessons, the field trip and the written tests are compulsory.

Examination
Written tests, home assignments, laboratory assignments and a field assignment. Written examination with graded marks.
