Course detail

Foundation Engineering

ÚSI-2BDZSAcad. year: 2016/2017

The course is aimed at establishing an overview of modern methods of building construction and carving out of a construction pit. It deals with technical aspects of the creation of structures, and a brief assessment of their risk analysis. It discussed the probability of failure of geotechnical structures. The subject develops students' knowledge of modeling of the underlying structures and foundation pits. There are given the technical risks associated with the implementation and functions of geotechnical structures - reliability, geotechnical causes of structural failures, landslides and their rehabilitation and the establishment of the landslide area, rock avalanches and ensure rock walls.
