Description Engineering Soil: (Geology for engineers, 3-phase model of soil, soil descriptions and classification).

Compaction: (compaction theory, compaction testing, earthworks).

Stress in soils (vertical and horizontal stresses, states of shear, Mohr’s circles of stress, effective stress).

Seepage: (Hydraulic head, Darcy’s law, permeability and its measurement, flow through layered soil, flownets, piping, drainage and groundwater control)

Compression and consolidation: (Compression and consolidation, Consolidated states, laboratory testing, 1-D theory of consolidation, settlement predictions)

Shear strength: (Shear failure (Peak, ultimate and residual), Mohr-Coulomb criterion, undrained vs. drained shear, laboratory testing).

Site Investigation: (Stages of a SI desk study, exploratory investigations (trial pits and boreholes), soil samples, Field tests (plate bearing tests, SPT, cone penetration test and their uses, SI reports).

Basic Geotechnical design: (Geotechnical parameters, design charts and correlations, use of simple charts in parameter estimation)
Learning Outcomes By the end of the module students should be able to:
  • explain the geotechnical properties of soils and rocks for civil engineers, and how soil/rock can be described for engineering purposes
  • assess effective stress on the engineering behaviour of soil and how changes can be determined during different loading and ground water environments
  • explain why water flows through soils, how seepages affects the behaviour of a soil
  • measure permeability and understand what controls the permeability of a soil
  • identify volume changes that occur in soils by using theoretical prediction, laboratory measurements and their use in settlement predictions
  • estimate the response of a soil to shear stresses through the Mohr-Coulomb criterion, un-drained and drained responses, laboratory measurements and considering peak, ultimate and residual strengths
  • value site investigations and the various stages undertaken, including desk study, exploratory investigations, field and laboratory testing and reporting
  • apply principles of soil mechanics in geotechnical design, including parameter selection and basic methods employed in the design process
