Course detail

Mathematical Modeling of Geotechnical Constructions

FAST-CF053Acad. year: 2017/2018

The content of the course is mainly focused on the solving the geotechnical constructions using mathematical modeling (finite element method). In the first part of the course, basics of continuum mechanics will be repeated. Emphasis is put on a description of soil constitutive modes, starting with the simplest elastic models, continuing with more complicated models involving plastic (irreversible) component of deformation. In the following part of the course, students will be familiar with process of creating a mathematical model both from a theoretical and practical point of view. Acquired knowledge will be applied in order to solve particular geotechnical constructions (shallow foundations, deep foundations, earth retaining structures, embankments, cuts, underground structures) using Plaxis 2D software. In the last part of the course, student will prepare and present term projects.
