CIV2242 · Geomechanics 1

Overview

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 2D seepage, effective stress theory, stresses in a soil mass and shear strength.

Assessment

The Handbook lists an examination for this unit.

Continuous assessment: 50% Final assessment: 50% This unit contains hurdle requirements that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Requisites

The Handbook lists no prerequisite, corequisite or prohibition for this unit.

Learning outcomes

1. Discuss the knowledge of basic engineering geology in designing civil infrastructure on soils/rocks.
2. Select and report results of geotechnical site investigations.
3. Identify and classify soils and rocks based on standard classification systems.
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. Calculate quantities of water flowing through soils and evaluate its effect on soils stresses and stability.
7. Identify and determine appropriate shear strength parameters of soils/rocks for engineering design.
8. Predict incremental stresses in soils/rocks due to applied loads.

Workload

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours of independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.
