CIV2242 - Geomechanics 1 - 2018

The unit covers all aspects of geomechanics at an elementary level, as well as basic engineering geology, formation and weathering processes, sedimentary, igneous and metamorphic rocks, soil and rock forming minerals, geological mapping and modelling, site investigations, in-situ testing, engineering classification of soil and rock, weight-volume relationship, and the two/three phase model. It also includes effective stress theory, stresses in a soil mass and shear strength. The unit includes elementary-level application of geomechanics knowledge in the analysis and design of shallow and deep foundations.

At the completion of this unit, students should be able to:

1. Use knowledge of basic engineering geology in designing civil infrastructure on soils/rocks
2. Plan and interpret results of geotechnical site investigations
3. Classify soils and rocks including mineralogical compositions
4. Identify different phases in soils and determine their densities, void ratios, porosities
5. Determine total, effective and pore water pressures in soils/rocks including implications of loading on drainage behaviour of soils/rocks
6. Identify and determine appropriate shear strength parameters of soils/rocks for engineering design
7. Estimate incremental stresses in soils/rocks due to applied loads
8. Use knowledge of soils/rocks in designing simple foundations

Continuous assessment: 50%

Examination (2 hours): 50%

Students are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

One 2 hour lecture plus one 1 hour lecture, one 2 hour practice class, one 1 hour laboratory and 7 hours of private study per week
