BSc Geological Engineering · KNUST

Introduction: Soils in civil engineering, syllabus for CE 260, evaluation procedure; Formation of soils: Weathering - physical and chemical weathering; sedimentary and residual soils; Index Properties: Particle size distribution; sieve analysis, sedimentation, Stoke's Law, hydrometer method; Atterberg Limits: Determination of liquid, plastic and shrinkage limits, definition of activity of a clay; Soil Classification Systems: soil classification; the need for soil classification, Cassagrande's extended system, the Unified Soil Classified System, the AASHITO system; Phase Relations: Definitions - water content, void ratio, dry density, degree of saturation, and calculations; Soil Compaction: Moisture density relationships, properties of compacted soils; Laboratory compaction; Various specifications (AASHITO, Mod. AASHITO, Proctor, Mod. Proctor,…) Compaction Specification: types of specifications, compaction equipment, compaction control testing; Mohr Circle of Stress: Principal stresses, Mohr's circle of stress, calculation of magnitude and direction, Mohr-Coulomb failure criterion; Shear Strength: Measurement of strength - triaxial test, the unconfined compression test, the direct shear test; Effective stress: The concept of effective stress, calculation of effective stresses, geostatic stresses; Stress Analysis in Rocks: Mechanical properties of rocks, uniaxial compressive strength, tensile strength, shear strength (unconfined & triaxial); Rock Mass: stress strain relations; rock mass properties, joint analysis and classification, effects of joints.
