Course abstract

The course explores the physical and mechanical properties of soil, basic concepts of soil mechanics, stress in subbase soils and its detection; determination of foundation deformations. BIM system software (MS Excel, AutoCAD) is used in the course.

Learning outcomes and their assessment

Knowledge: of subbase soil properties, of basic concepts of soil mechanics, of stress detection methods in subbase soils, subbase soil calculation methods; attendance of lectures, discussion;
Skills: choosing appropriate subbase soil strength and deformation calculation methods and perform the calculations; individual calculation papers;
Competence: ability to rationally choose structural solution of foundation regarding the subbase soil structural properties; test (conversation).
