Learning Outcomes
On successful completion of this course, the student should be able to:

1. Examine the occurrence and flow of water through soils and discuss the impact soil water has in engineering practice.
2. Determine and evaluate the shear strength parameters of soils.
3. Determine the earth pressure on, and analyse the stability of, earth retaining structures.
4. Analyse the stability of earth slopes.
5. Determine the bearing capacity of shallow and deep foundations.
6. Understand the process of consolidation and estimate consolidation settlement.
7. Describe the causes of liquefaction and how these can be controlled to reduce the chances of liquefaction
• Darcy’s Law; Co-efficient of permeability; Effective stress, Wick drains, soakage pit tests,
• Coulomb’s law; Shear box; Tri-axial compression, Cone penetration test, standard penetration test.
• Types of retaining structures; Rankine’s or Coulomb’s method; Stability Analysis
• Stability of cohesive- and non-cohesive slopes; Stability curves
• Terzaghi’s equation; bearing capacity coefficient; shape factors; strength redction factors; Types of Piles
• Stress at depth; Consolidation test results; Coefficient of volume change/Compression index, settlement of foundations
• Causes of liquefaction, soil types prone to liquefaction, ways to reduce the effects of liquefaction.
