Summary
The subject belongs to those one underlying the geotechnical engineering. On the basis of a knowledge of static, elasticity, engineering geology and hydrogeology it pursues the fundamental topics involved in the shallow and deep foundations structures, the design methods aimed at evaluating the ground load bearing capacity and the foundation settlement, the foundation in difficult ground conditions and in sensitive urban areas. An attention is also given to the foundation failures, foundation failure remediation, monitoring methods, modelling, observation method and risk assessment. The undergraduate gains knowledge about the foundation structures and evaluation of the foundation grounds. He learns to calculate the frequent foundation structures utilising the up-to-date design methods satisfying the contemporary local (Czech ČSN) and European (EC7) legislative and technical standards. Foundation; rock environment; soil; foundation construction; bearing capacity; settlement; reconstruction of foundation constructions; foundation constructions failures; reconstruction of foundations.

2. Survey of building site (stages, types). Methodology of limit states, geotechnical categories. Stress under foundation (origin, due to loads).
3. Shallow foundations – pads, strip footings, foundation slabs, design of connection footing and upper construction, classification of foundation soils, co-operation of supporting structure of subbase, spatial foundation structure.
4. Design and check of shallow foundation – 1st limit state (bearing capacity – horizontal and vertical), factors affect to bearing capacity, influence of groundwater level. Design according to EC 7 (Eurocode).
5. Settlement of shallow foundation – 2nd limit state, failure of buildings, time development of shallow foundation settlement.
6. Reconstruction of shallow foundations. Design, temporary insurance, underpinning foundation, increase of stiffness
