Geotechnical Engineering, Advanced Course

The course focuses on practical application of the finite element method in geotechnical engineering with emphasis on problem definition, input parameters and evaluation of results. Various elasto-plastic material models for soils are described, discussed and applied. The students shall in exercises run advanced numerical simulations of soil structure interaction. The exercises cover simulations of laboratory tests for parameter determination, embankments on soft ground, foundations and supporting structures for construction pits. Seepage, consolidation and time dependent settlements are included. The course aim for using advanced digital tools.
