Aims This unit of study aims to introduce engineering students to the fundamentals and basic techniques used in Geotechnical Engineering. In particular, it aims to introduce students to design and construction principles of Civil / Geotechnical Engineering type structures such as earth retaining structures, shallow foundations, residential slabs and footings, deep foundations, and the assessment of stability for sloping ground.

Unit Learning Outcomes Students who successfully complete this Unit should be able to: 1. Analyse earth retaining structures to determine active, passive and at rest lateral earth pressures (and associated forces) based on Mohr circles and the MohrCoulomb failure criteria of soils (K1, K2, K3, K6, S1, S2, S3). 2. Determine bearing capacities for shallow foundations and be able to design suitable footing systems for various soil conditions based on strength and settlement criteria. (K1, K2, K3, K6, S1, S2, S3). 3. Appreciate the soil – structure interaction model for residential slab footings and active type soils, and thus be able to select appropriate shallow footing systems for residential structures and design them in accordance with Australian Standard AS2870 for various site and soil conditions (K1, K2, K3, K4, K6, S1, S2, S3, A2, A7). 4. Design deep foundations based on strength and settlement criteria for various sites and soils conditions (K1, K2, K3, K6, S1, S2, S3). 5. Analyse sloping ground against slope failure and assess the factor of safety using multiple methods of analysis (K1, K2, K3, K6, S1, S2, S3). 6. Conduct a basic technical investigation by performing a literature review, compile and analyse the information gathered, and produce a brief and concise (journal style) report with an appropriate conclusion (A2, A4, A5, A7). 7. Perform a brief and concise oral presentation of technical material, which simulates a conference style presentation (A2, A4, A5, A7).

Unit Improvements Feedback provided by previous students through the Student Survey has resulted in improvements that have been made to this unit. Recent improvements include: • • •

Newly recorded lectures due to online delivery mode. Newly recorded selected tutorial solutions due to online delivery. The time for the online unit quizzes will be extended to 72 hours.

Other recent changes / improvements made are: • •

An assignment week has been included where no lectures will be scheduled for week 7. This will enable more time to be spent on the Unit 3 design assignment. Tutorial workbooks have been developed for units 1, 2, 3 and 4, which should allow a more efficient use of time when solving the tutorial style problems.

Tasks and Details

Three online unit quizzes (for units 1, 2 and 4) have been developed and scheduled for this subject. These online quizzes have been designed to help students judge their own progress and level of comprehension of the subject material. Note that only the two best quiz results will contribute towards the final mark of the subject (i.e. two quiz results at 10 % each). As a result of this, no special or make-up quizzes will be provided. Note: Students must retain all assessed material that contributes to their final grade up until such time as the final grades are published. b) Minimum requirements to pass this Unit To pass this unit, you must: • achieve an overall mark for the unit of 50 % or more, and c)

Examinations If the unit you are enrolled in has an official examination, you will be expected to be available for the entire examination period including any Special Exam period. Note: There will not be any formal exam for this unit in 2020 due to COVID-19 restrictions and University policy. However, you are still expected to be available for the entire final assessment period including any Special Assessment period.

d) Submission Requirements Assignments and other assessments are generally submitted online through the Canvas assessment submission system which integrates with the Turnitin plagiarism checking service. Please ensure you keep a copy of all assessments that are submitted. In cases where a hard copy submission is required an Assessment Cover Sheet must be submitted with your assignment. The standard Assessment Cover Sheet is available from the Current Students web site (see Part C). e)

Extensions and Late Submission Late Submissions - Unless an extension has been approved, late submissions will result in a penalty. You will be penalised 10% of your achieved mark for each working day the task is late, up to a maximum of 5 working days. After 5 working days, a zero result will be recorded.

Referencing To avoid plagiarism, you are required to provide a reference whenever you include information from other sources in your work. Further details regarding plagiarism are available in Section C of this document. Helpful information on referencing can be found at http://www.swinburne.edu.au/library/referencing/

g) Groupwork Guidelines A group assignment is the collective responsibility of the entire group, and if one member is temporarily unable to contribute, the group should be able to reallocate responsibilities to keep to schedule. In the event of longer-term illness or other serious problems involving a member of group, it is the responsibility of the other members to notify immediately the Unit Convenor or relevant tutor. Group submissions must be submitted with an Assignment Cover Sheet, signed by all members of the group. All group members must be satisfied that the work has been correctly submitted. Any penalties for late submission will generally apply to all group members, not just the person who submitted.

Student behaviour and wellbeing All students are expected to: act with integrity, honesty and fairness: be inclusive, ethical and respectful of others; and appropriately use University resources, information, equipment and facilities. All students are expected to contribute to creating a work and study environment that is safe and free from bullying, violence, discrimination, sexual harassment, vilification and other forms of unacceptable behaviour. The Student Charter describes what students can reasonably expect from Swinburne in order to enjoy a quality learning experience. The Charter also sets out what is expected of students with regards to your studies and the way you conduct yourself towards other people and property. You are expected to familiarise yourself with University regulations and policies and are obliged to abide by these, including the Student Academic Misconduct Regulations, Student General Misconduct Regulations and the People, Culture and Integrity Policy. Any student found to be in breach of these may be subject to disciplinary processes. Examples of expected behaviours are: • conducting yourself in teaching areas in a manner that is professional and not disruptive to others •

•

following specific safety procedures in Swinburne laboratories, such as wearing appropriate footwear and safety equipment, not acting in a manner which is dangerous or disruptive (e.g. playing computer games), and not bringing in food or drink following emergency and evacuation procedures and following instructions given by staff/wardens in an emergency response

Canvas You should regularly access the Swinburne learning management system, Canvas, which is available via the Current Students webpage or https://swinburne.instructure.com/ Canvas is updated regularly with important unit information and communications.

Communication All communication will be via your Swinburne email address. If you access your email through a provider other than Swinburne, then it is your responsibility to ensure that your Swinburne email is redirected to your private email address.

Academic Integrity Academic integrity is about taking responsibility for your learning and submitting work that is honestly your own. It means acknowledging the ideas, contributions and work of others; referencing your sources; contributing fairly to group work; and completing tasks, test...
