Subject aims expressed by acquired skills and competences
The course studies the behavior of rock and especially soil bodies,
which are either directly zeminovou structures or the environment in which the
mining activities carried out or are in newly built structures in the direct
contact. The introductory part of the course is devoted to the basics of soil mechanics, particularly for properties of rocks and soils and their behaviour under different conditions and under
influence their own or external load. This theoretical part of the course
solution followed by application of geotechnical engineering problems, including slope stability, earth pressures, filters, problems in the consolidation of soils, the general
modelling in geotechnics and foundations and principles of geotechnical monitoring.

Summary
Obsahem předmětu je studium chování horninových a zejména zeminových těles,
která jsou buď přímo zeminovou konstrukcí, nebo jsou prostředím, ve kterém je
hornická činnost prováděna, nebo jsou s nově budovanou konstrukcí v přímém
kontaktu. Úvodní část předmětu je věnována základům mechaniky zemin, zejména z
hlediska vlastností hornin a zemin a jejich chování za různých podmínek a pod
vlivem vlastního či vnějšího zatížení. Na tuto teoretickou část předmětu
navazuje řešení aplikačních úloh geotechniky, k nimž patří stabilita svahů,
zemní tlaky na konstrukce, filtry, úlohy z oblasti konzolidace zemin, obecné
modelování v geotechnice a princip a základy geotechnického monitoringu.

Exercise:
During the semester, students go through some form of exercise. Their goal
is to acquaint students with procedures for determining characteristics of rocks, with the classification
rocks for engineering purposes and methods of calculation, respectively. computational solution
models, application of geotechnical engineering problems. Forms of exercise are the laboratory (laboratory
geotechnical engineering) and computational (classrooms, respectively. mathematical modelling laboratory).
Tasks carried out in laboratory exercises:
- Specific weight and bulk soil
- Grain size analysis - a grading curve
- Atterbergovy bounds consistency
- Oedometrická test (packaged unit)
- Proctor test (standard Proctor)
Tasks carried out in the computer exercises:
- Identifying and descriptive of the physical properties of rocks from the specified values
- Classification and the classification of rocks according to ČSN 73 1001 from the assigned values
- Solving problems in the consolidation of soils, stresses in the subsoil of the surcharge
- Preparation and solution of a mathematical model given geotechnical problems (stability
slope, you rock stress in the body of the surcharge, etc.).
