Teaching & Learning Strategies: Lectures Demonstrations Project work Practicals Presentation Private study
Module Aim: (a) To understand the physical and mechanical properties of soils; (b) To develop a general appreciation of environmental issues and their vulnerability to engineering development projects; (c) To develop a general appreciation of sustainable construction principles as it relates to Civil & Geotechnical Engineering; (d) To be able to determine parameters from soil testing to characterize soil properties, (d) soil strength and soil deformations, (e) to be able to apply the principles of soil mechanics to analyze and design simple geotechnical systems; (f) To increase the understanding of the effects of construction on groundwater and the effects of groundwater on construction; (g) To develop the skills required to evaluate factual Geotechnical Engineering reports; (h) To develop the skills required to assist in writing an interpretative Geotechnical engineering reports; (i) To recognise when simple geotechnical analysis and design are insufficient to safely or cost effectively evaluate/design a project; (j) To equip the student to operate as a Civil Engineer with a good understanding of Geotechnical Engineering; (k) To equip the student with the skills and information necessary to undertake post-graduated study
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Assess the information contained in factual geotechnical reports including laboratory test results
LO2 Prepare well presented interpretative geotechnical calculations and carry out simple geotechnical design and analysis
LO3 Assess ground conditions to evaluate SI requirements for field work, sampling and testing
LO4 Understand the value of desk study information and its role in preparation of factual and interpretative reports
