Course Aim
To provide a deeper understanding of some areas of soil mechanics and foundation engineering and to introduce the student to ongoing research in some areas of soil mechanics. A number of subjects well aimed for student thesis work are also introduced. Further, the intention is to train the students capability of finding information and to present it in the form of a small research paper.

Contents

Soil Dynamics (25%)

Principles of soil dynamics based on mass oscillator, wave propagation and equivalent elastic soil behaviour, Introduction into the basics of geotechnical earthquake engineering, vibration and vibration protection, liquefaction

Strength and deformation properties of soils-constitutive modelling (30%).
Laboratory and field methods for determination of strength and deformation properties of soils. Behaviour of soils under compression and shear. Reversible and irreversible deformation. The concepts of contractance, dilatancy and critical state.Laboratory test with performance of a triaxial test on a soil sample for termination of its strength and deformation properties. Theories for the constitutive modelling of soils, especially the flow theory of plasticity. Example from Cam Clay model (critical state theory). Computer laboratory with the application of a constitutive driver for the simulation of a triaxial test.


Heat transfer mechanisms and frost action in soils (5%).
Frost susceptibility (classification).Ice lens formation. Frost heave. Unfrozen water in frozen soil. Models for calculation of frost heave in a freezing soil. Permafrost and its technical and economical consequences.

Slope stability and landslides (30%).
Different slide mechanisms. Classical methods of slope stability analysis with emphasis on drained analysis (co-analysis).Computer laboration with the drained analysis of a slope, comparison of different theories. Numerical methods of slope stability analysis. Geotechnical investigations inslide potential areas. Computer simulations with a commercial finite element software.
