- Description and characterisation of soils: unit weights, porosity and void ratio, water content and degree of saturation, grain size distribution, consistency limits, mineralogical and grain size-based soil classifications.
- Fundamentals of mechanics: stress and strain concepts, Mohr’s circles, Young’s modulus, Poisson’s number, basic material behaviours (elasticity, plasticity, linear and nonlinear behaviours).
- Water in soil and effective stresses: different forms of water in soil, capillarity, principle of effective stresses, hydrostatic pressure, stress profiles in the ground, water flow and hydraulic conductivity, critical hydraulic gradient, theory of consolidation, drained and undrained loads.
- Compressibility and volume changes: uniaxial, isotropic and oedometric compressions, compressibility parameters and state lines, normally consolidated and overconsolidated soils, soil stress history, experimental determination of volume change behaviours, settlements, pressure coefficient at rest, consolidation factor, volumetric creep, swelling and swelling pressure, examples, and case studies.
- Strength: stress-strain diagram, Mohr-Coulomb strength envelope, dilatancy, peak strength, critical state strength, critical state, strength envelope shapes, true and apparent cohesion, residual strength. Use of peak, critical, and residual strength in practice, their determination in laboratory: direct and ring shear boxes, triaxial devices, angle of repose method; stress paths and their use, undrained strength, its determination, and use.
- Experimental soil mechanics: field geotechnical investigations and laboratory tests, planning and executing a geotechnical campaign, soil sampling, laboratory determinations.
- Tutorials and exercises for which the students are expected to prepare individual reports that will count towards the final evaluation. The exact number and content of the tutorials and exercises will be agreed during the course.
