What this paper is about

Edit What this paper is about Content

Building on specialist geotechnical knowledge gained from papers ENGCV231 and ENGCV331, this paper advances the understanding of geotechnical engineering and its relevance to the Waikato, Bay of Plenty and wider New Zealand through a review of the behaviour of materials and application of this to design. The paper links shear strength and volume change through stress-path testing and provides an analysis of soils by means of drained and undrained triaxial tests. It also discusses the unusual nature of New Zealand soils and how these may differ from classical soil mechanics. In addition, the more advanced understanding of soil mechanics will be used to explore and design a variety of geotechnical processes and systems relevant to shallow foundations, deep foundations, embedded retaining walls, soil nails, anchors and geosynthetics.

The learning outcomes for this paper are linked to Washington Accord graduate attributes WA1-WA11. Explanation of the graduate attributes can be found at: https://www.ieagreements.org/assets/Uploads/Documents/IEA-Graduate-Attributes-and-Professional-Competencies-2021.1-Sept-2021.pdf

How this paper will be taught

Edit How this paper will be taught Content

This paper is delivered through a combination of lectures, tutorials and laboratories. Students should attend all lectures and the tutorial to assist with their learning. We find that students who attend in person achieve better results in this paper and build a better comprehension of the concepts taught.

Tutorials and laboratories are an essential part of learning for this paper. Students are required to attend laboratories to collect data and observations for the associated assessments.

Learning Outcomes

The learning outcomes are assessed using a combination of:

Laboratories (20%)

There are a total of two laboratory sessions, one a triaxial test in week 30 and the other testing in relation to liquefaction assessment in week 37. You will be required to analyse and interpret data from each test. Additional assignment questions will be provided as part of the laboratory work to solidify the processes and mechanics being investigated.

Test (20%)

The text will be closed book with ONE double-sided A4 cheat sheet page allowed and is worth 20% of your final grade. The format will be discussed in the lectures before the exam. A full formulae booklet will be provided.

Design Portfolio (60%)

The design portfolio will be worked on throughout the semester. You will be provided with project details at the start of the course and prepare a desktop study, soil profile, calculate soil parameters, undertake a liquefaction assessment, design shallow and deep foundations and a retaining wall, prepare a final geotechnical assessment report and a video for your client. The design portfolio will be submitted in stages. You will be provided with supporting information as required for each stage of the work.

The portfolio grade will be distributed across the activities undertaken as follows: desktop study, soil profile and soil parameters (10%), liquefaction assessment (5%), geotechnical design (foundations & retaining wall) (24%), interpretative report (16%), video (5%).

Edit How you will be assessed Content

The internal assessment/exam ratio (as stated in the University Calendar) is 100:0. There is no final exam. The final exam makes up 0% of the overall mark.

The internal assessment/exam ratio (as stated in the University Calendar) is 100:0 or 0:0, whichever is more favourable for the student. The final exam makes up either 0% or 0% of the overall mark.
