Paper Description

Edit Paper Description Content
Building on specialist geotechnical knowledge gained from papers ENGCV231 and ENGCV331, this paper provides an advanced understanding of geotechnical engineering from a variety of perspectives. Firstly, the paper explains that shear strength and volume changes are linked and dependent on stress history. Secondly, New Zealand soils are often residual soils which can result in behavior different from classical soil mechanics of older sedimentary soils found in Europe and North America. Both of these perspectives will be taught using stress-path testing and analysis of soils by means of drained and undrained triaxial tests combined with further studying of engineering geology. In addition, the more advanced understanding of soil mechanics will be used used to explore and design a variety of geotechnical processes and systems such as soil treatment techniques, soil structure interaction along with selection of design parameters.

Assessment

Edit Assessments Content

The learning outcomes are assessed using a combination of:

Laboratories (15%)

There are a total of three laboratory sessions for in-situ soil tests that are conducted over the first six weeks of the semester. You will be required to analyse and interpret data from each soil test and provide a brief report summarising the results. Each of the three laboratory reports will be worth 5% of your final grade.

Design Portfolio (35%)

With the information from the laboratory testing you have completed and the additional project details you will be provided, you will be asked to prepare a geotechnical cross section, calculate soil parameters and complete some geotechnical designs. You will prepare a design portfolio which will include a geotechnical interpretative report to summarise your findings and support your design recommendations. Your portfolio will be submitted in the last week of lectures and you will be required to provide a 5 minute video discussing your design decisions. The portfolio grade will be distributed across the activities undertaken as follows: geotechnical cross section (5%), soil parameters (5%), geotechnical design (10%), interpretative report (10%), video (5%).

Exam (50%)

The exam will be open book and is worth 50% of your final grade. The format will be discussed in the lectures before the exam.
