Prerequisite Modules:
Rationale and Purpose of the Module:
This module introduces construction students to the origins and engineering
behaviour of one of the most common construction materials encountered on every
construction project.
The course is designed to challenge the student to seek the key concepts in geology
and soil mechanics and apply these concepts in projects and self-directed learning to
achieve the following key objectives:
Develop a clear understanding of the role of geology and soil mechanics in achieving
a successful construction project.
To generate enthusiasm for the subject through in-class demonstrations and case histories.
Syllabus:
Role of geology in civil engineering, Burland's geotechnical problem solving model; soil composition and chemistry, clay bonding and double layer; classification and description of soils; phase relationships; soil compaction and ground improvement; effective stress principle including the influence of water flow on soil behaviour; permeability and flow nets; basics of site investigation.
Learning Outcomes:
Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)
On successful completion of this module, students will be able to:
1) Graph the results of a laboratory experiment using MS Excel, interpret the results and write a technical report on the experiment.
2) Write engineering descriptions for soil sampled from a trial pit
3) Determine the classification of a soil using laboratory test results
4) Use phase relations to compute soil compaction properties.
5) Compute effective stresses in soils under various groundwater regimes.
6) Perform a seepage analysis for cofferdams and earthen & concrete dams including checks for hydraulic failure.
7) Defend decisions made in the earthen dam project.
Affective (Attitudes and Values)
On successful completion of this module, students will be able to: a) Appreciate the role of soil mechanics in creating a safe and serviceable structure.
Psychomotor (Physical Skills)
None
How the Module will be Taught and what will be the Learning Experiences of the Students:
The module adopts an active learning pedagogy. Students work collaboratively throughout the semester to develop the knowledge required to find a creative solution to an open-ended design problem. Working within a group highlights an individual's responsibility to contribute towards a successful team performance.
At the end of the semester each team articulate their design through either an online video or a written design report in addition to participating in a team interview. Lectures and tutorials are provided to assist with the technical content of the module.
The module promotes a sustainability theme by using natural soil as the engineering structure rather than other construction materials such as concrete and steel. This choice highlights how carbon emissions can be reduced on certain civil engineering projects.
