Subject aims expressed by acquired skills and competences

Students gain an overview of the contents of soil and rock mechanics as the starting and basic disciplines of geotechnical engineering tasks. They learn to solve problems that are related to the state of stress, deformation, stability and a failure of rock and soil masses. Gets the basic prerequisite for an objective assessment of foundation conditions for knowledge-based methods for design the bearing capacity and settlement, especially in the spread footings.

Summary

This course is the first phase of the study of behavior and especialyy soil mass that are either directly soil structures or the environment in which the construction activities are conducted. Also can be a newly constructed building structures in direct contact. The introduction is devoted to properties of soils and their behavior in real conditions and under the influence of their own or external load. The theoretical part of the course and the grading system for rocks and soils (foundation soil in general) are linked into a common application solutions to geotechnical engineering, including earth pressures, filters, drainage pits, problems in the consolidation of soils, methods of treatment of soil properties and soil compaction, modeling in geotechnical, slope stability and slope failure remediation. The second phase addresses the issue of designing methods of foundation design and assessment.

Subject syllabus:

1. Introduction to problem of soil mechanics. Soil like working area. Descriptive properties of soil (grain-size curve, volumetric and specific weight, moisture and degree of saturation). Soil classification system. Granulometric test. 2. Physico-chemical properties of soil (Atterberg limits (liquid limit, plastic limit, shrinkage), plasticity index, swelling, consistency. Type of water in soil, movement of water in pore and his influence on construction, Darcy law). Pore pressure, principle of effective stresses. 3. Strenght properties (elasticity modulus, Hooke´s law, compressibility, creep). Deformational properties (shear strenght, cohesion – mesurement, interpretation). 4. Survey of building site (stages, types). Methodology of limit states, geotechnical categories. Stress under foundation (origin, due to loads). Triaxial measurement of soils. 5. Shallow footings – pads, strip footings, foundation slabs, design of connection footing and upper construction, interaction foting vs. subsoil. 6. Design and check of shallow foundation – 1st limit state (bearing capacity), factors affect to bearing capacity. 7. Settlement of shallow foundation – 2nd limit state, failure of buildings, primary and secondary consolidation of soils (oedometric measurement, time of consolidation – Taylor, Cassagrande methods), degree and coefficient of consolidation (U, cv). 8. Foundation pits and their timbering. Braces sheeting, sheet-pile walls, pile walls, diaphragm walls – technology and utilization, static design. Foundation pit dewatering. 9. Lateral earth pressure of soils on construction (types of earth pressure – active, passive, at rest) by Rankine and Coulomb´s theory. Design of retaining wall (gravity wall, cantilever wall, masonry wall). 10. Deep foundations – basic element. Caissons, open cassions, piles (distibution (displacement, replacement), bored piles. Design of axial bored piles – limit bearing capacity, limit loading curve. 11. Improvement of subsoil (compaction, anchors, injection (classical injection – sealing, hardening, compesation, jet grouting) freezing. Foundation underpinning. 12. Foundation in special condition – undermining areas, unstable territory, embankment, dumping ground. 13. Case history.
