Brief Handbook Description: This is an advanced course on geotechnical engineering. The Unit of Study will focus on the design and analyses of geotechnical applications related to energy and sustainability. This course covers essential geotechnical design concepts related to some of the current and emerging energy projects, starting from the governing mechanisms controlling heat and mass transfer, to designing geothermal foundations and geological storage facilities, as examples. Other energy geotechnical problems include the design and analyses of offshore foundations for oil and gas platforms, which must sustain unique and harsh loading conditions, and carbon geosequestration facilities subjected to high temperatures, pressures and hydrological conditions.

The course concerns with the constitutive behaviour of soils, including stress, strain, heat and mass transfer, and the application of this knowledge in practical engineering problems. Theme topics related with these materials will be discussed with specific emphases on the areas of energy and environmental engineering. This course aims to develop theoretical and numerical skills for students interested in structural and geotechnical engineering.

T&L Activities: The course will contain the following aspects:

• Lectures: providing background information, concepts, and theoretical and analytical approaches in geotechnical topics related to energy and sustainability.

• Tutorials: developing analytical and computational problem-solving skills through a range of practical examples.

• Laboratory works: for students to experiment the thermo-hydro-mechanical properties of soils and critically assess the predictions of existing engineering models against the experimental results.

• Group projects: developing student’s collaborative and co-operative skills and ability to design optimal engineering solutions on complex practical situations.

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Attribute Development Method Attribute Developed
Soil modelling and design project assignments provide practice in evaluation and preparation of laboratory data, comparative evaluation of modelling methods and interpretation of complex results. (1) Maths/ Science Methods and Tools (Level 4)
Introduction to poromechanics framework for considering THM behaviour and practice in applying this framework to new and unfamiliar data sets. Three assignment exercises provide practice in use of various modelling methods for predicting soil behaviour and determining soil parameters for engineering design. (2) Engineering/ IT Specialisation (Level 4)
Two assignments and one quiz provide practice in investigating and analysing complex and ambiguous geotechnical engineering situations and determining relevant design parameters. (4) Design (Level 4)
Two assignments for provide understanding of the complex nature of these engineering problems for developing and broadening their research and critical thinking skills. (6) Communication and Inquiry/ Research (Level 4)

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table 2018.

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.

(6) Communication and Inquiry/ Research (Level 4)
1. Ability to effectively source information from literatures, critically analyse the conclusions, and identify the assumptions used and limitations of the existing approaches.
(4) Design (Level 4)
2. Ability to determine the design parameters for given geotechnical engineering conditions based on a rational consideration of soil factors.
(2) Engineering/ IT Specialisation (Level 4)
3. Ability to identify the contributing factors influencing thermo-hydro-mechanical (THM) behaviour of soils and explain their interactions, using the theoretical framework of poromechanics.
4. Ability to explain models used in predicting THM behaviour of geo-materials, including their practical requirements and potential limitations.
5. Ability to operate the poromechanics models using real laboratory data to produce meaningful results, and critically evaluate the quality of lab data and ensure readiness for use in soil behaviour modelling for energy geotechnics.
(1) Maths/ Science Methods and Tools (Level 4)
6. Ability to produce soundly-based interpretations of soil modelling results, giving due consideration to assumptions and limitations of the data used and those to the model used.
7. Ability to engage with alternative possible interpretations of the same results, critically examine the merits of each and draw appropriate conclusions.

Assessment Description: Assessment in this unit is based on a combination of two quizzes and three assignments. The quizzes are 1.5 hours each and test understanding of key concepts and ability to apply them in working with unfamiliar sets of data. The three assignments require student to work through modelling exercises of progressively increasing levels of challenge. Students aiming for higher grades should note the ability to evaluate and interpret complex data, to weigh up alternative explanations and to recognise limitations of conclusions reached (represented by Learning Outcomes 4-7) are important for high achievement in this unit.
Grading:
Grade Type Description
