Prerequisites: Theory of structures
Target skills and knowledge: Aim of the course is to provide the basic notions of the subject, with particular attention to the mechanical behaviour of soil and to the issues relevant to the phenomena of soil-foundation interaction, both from a theoretical and practical point of view, in a global united vision.
Examination methods: Written test containing n.3 exercises e n.2 theory questions. The written test lasts 2 hours. An oral test must be passed successfully in order to obtain a final grade greater than 28/30.
Assessment criteria: Evaluation of the student level will be based on an understanding of the topics of the lectures, on the acquisition of concepts, theories and methodologies on which it is based geotechnical engineering and the ability to apply them in specific exercises. To pass the final test the student must demonstrate adequate learning skills and have independent judgment.
Course unit contents: The educational activities will be developed through lectures and exercises.
Planned learning activities and teaching methods: INTRODUCTION TO GEOTECHNICAL ENGINEERING PROBLEMS.

GEOLOGICAL CHARACTERISTICS OF SOILS. Composition, formation and type of land. Clay minerals. Surface forces. Adsorbed water. Structure. Activity.
COMPACTION AND STABILIZATION OF SOILS. Compaction of fine and coarse grain solis. Geotechnical properties of compacted soils. Laboratory tests. Checking test in situ.
HYDROSTATIC WATER IN SOILS. Capillarity. Groundwater table and vadose zone. Shrinkage and swelling. Total stresses, effective and neutral. Relationships between horizontal and vertical stresses.
FLUID FLOW IN SOILS. Darcy's law. Measurement of coefficient of permeability. One- and two- dimensional seepage e flow nets. Seepage force. Quicksand. Liquefaction.
COMPRESSIBILITY OF SOILS. Stress history. Preconsolidation stress. Normally- and over-consolidated soils. One-dimensional consolidation tests. Components and calculation of settlement. In situ determination of the compressibility parameters.
TIME RATE OF CONSOLIDATION. The connsolidation process. Terzaghi's one-dimensional consolidation theory. Determination of coefficient of consolidation and permeability. Secondary compression.
DISTRIBUTION OF STRESS AND SETTLEMENT ANALYSIS. Settlement of a shallow foundation. Stress distribution. Immediate settlement. Settlement due to the primary consolidation and secondary compression.
MOHR CIRCLE, FAILURE CRITERIA, STRENGTH TESTING. State of stress at one point. Stress-strain relationships and failure criteria. The failure criterion of Mohr-Coulomb. Laboratory tests for determining the shear strength of soils.
SHEAR STRENGTH OF SOILS. Behaviour of sands and clays under drained and undrained conditions. Factors affecting the shear strength of sands and clays. In situ tests. The coeffciient of earth pressure at rest. Pore pressure parameters. Residual strength.
SHALLOW AND DEEP FOUNDATIONS. Bearing capacity and settlements of shallow foundations (individual, strip and mat). Types of piles. Bearing capacity of vertically loaded piles.
RETAINING STRUCTURES. Earth pressure theories. Stability of rigid and flexible retaining walls. Braced exacavations.
Additional notes about suggested reading: the teacher will provide the student essays, viedo, quiz and powerpoint presentations available on the e-learning plattform Moodle.
