Shallow foundations: Types of shallow foundations. General shear, local shear, and punching failure of soils. Bearing capacity of a strip footing. The general bearing capacity equation. Foundation subjected to load eccentricity. Undrained and drained loading conditions. Bearing capacity of foundations on a slope. Bearing capacity according to Eurocode 7 (EC7). Bearing capacity under seismic loading. Bearing capacity of shallow foundations on rock. Settlements: types of settlements and allowable settlements. Elastic settlements. Settlements of shallow foundations on clays and sands. Deep foundations: Types of piles. Axial bearing capacity of piles. Settlements of piles. Retaining structures: Types of retaining structures. Earth pressures at rest. Active and passive earth pressures – Rankine and Coulomb theory. Earth pressures according to EC7. The role of groundwater. The role of external loading. Geotechnical design according to EC7: gravity walls, embedded walls (flexible retaining structures – cantilever sheet-pile walls, singly-anchored sheet-pile walls), propped and braced excavations. Retaining structures under seismic loading.

Learning Outcomes : Upon successful completion of the course, the student will be able to: • Correctly categorize the types of checks to be performed, determine the appropriate data, and select the appropriate methodologies for performing geotechnical checks in typical foundation and retaining wall projects. • Apply sufficiency check methodologies for ultimate and serviceability limit states of foundations and retaining walls according to Eurocode 7. • Understand the generated results of the checks and evaluate their correctness, describe the problem in correct terms, understand the failure mechanisms of the foundation soil or the retained soil. • Analyze the results of geotechnical checks and compare them with corresponding situations, correlating geotechnical and construction data on a case-by-case basis, and synthesize data in order to select the optimal technically and economically feasible foundation or retaining wall solutions. • Compare, interpret, and evaluate check results, and decide on their sufficiency and correctness.
