Learning outcomes
The course is an introduction to the physical properties and the mechanical behaviour of soil and provides the concepts that are essential to the geotechnical engineering practice.
Course contents
Introduction and preliminary remarks. Soil types and structures. Fine grained soil properties.
Soil properties and their determination from experimental results. Water content. Density. Particle relative density. Porosity and void ratio. Particle sized distribution. Atterberg limit. Permeability.
Mechanical properties of soil and their determination from experimental results. Compression (oedometer test theory). Angle of friction and cohesion: shearbox test, triaxial test.
In situ testing. Plate bearing test. Standard and cone penetration test. Vane shear test.
Equilibrium in soil. Vertical and horizontal stress in soil. Plastic limit equilibrium. Horizontal and sloping backfill.
Stress distribution in soil beneath loaded areas. Boussinesq theory. Frölich theory. Graphic approach. Fully rigid and flexible loading areas.
Stabilty problems. Bearing capacity. Frölich theory. Theory of Ritter, Prandtl, Caquot and Terzaghi.
Applications.
Earth pressure against retaing walls. Coulomb's theory and Rankine's theory; graphic solutions.
Stability of slopes. Landslide classification. Influence of the in ground water. Infinite slope analysis. Landslide monitoring. Fellenius and Bishop's methods. Methods of ground improvement: dewatering systems, reinforced soil retaing walls. Effect of the earth embankment constructios on a slope. Effect of escavation on a slope and stress path.
Pile foundations. Driven piles. Cast in place piles. Formulas to evaluate the bearing capacity of a single pile. Skin friction and point resistance.
