Description

Mohr's circle; time-dependent soil behaviour; settlement; capacity and failure of foundations; field investigations; slope stability; earth pressure theories and retaining structures.

This second course in geomechanics focuses primarily on the analysis of common geo-structures and foundations. It makes use of the soil mechanics concepts and calculations learned in ENCN 253 and familiarity with this material is assumed. Generally speaking, the course content has been developed on the assumption that ideas and understanding, as opposed to codes or rote-learned formulae, are the backbone of successful engineering – our aim is to understand the behaviour of soil, and then put this understanding to work to solve practical engineering problems and make decisions.

Learning Outcomes

  • The course is divided into eight modules of roughly equal weight and duration:

  • Undrained strength
  • Shallow foundations – ultimate capacity and failure
  • Shallow foundations – serviceability and settlement
  • Consolidation and related settlement
  • In situ testing and site investigation
  • Deep foundations
  • Slope stability
  • Retaining walls

    By the end of this course you should be able to:

    - Analyse the stability of common geotechnical structures and foundations using conventional methods, (Washington Accord WA1, WA3, WA5) (UC BCC6, GA2, EIE3, CE3)

    - Compare various in situ and lab-based testing methods for different soil types and scenarios, and interpret typical soil test data, (Washington Accord WA1 WA2) (UC BCC6, GA2, EIE3, CE3)

    - Describe and analyse the deformation of soil using effective stress-based principles and appropriate idealisations of soil behaviour, (Washington Accord WA1 WA3, WA5) (UC BCC6, GA2, EIE3, CE3)

    - Describe conventional methods of design for SLS and ULS for geo-structures, and how to use factors of safety. (Washington Accord WA1 WA3, WA5) (UC BCC6, GA2, EIE3, CE3)

Timetable Note

ENCN353 is taught as a conventional single-semester course, comprising two lectures (4 hours) per week, a weekly tutorial, two lab activities and two assignments. The lectures are used to convey the fundamental concepts and equations; the tutorials provide opportunities for examples on how to apply the theory and the equations learned; the labs help to confirm these concepts and better understand soil behaviour; and the assignment are structured to challenge the students to apply the theories to solve engineering problems.

Course notes: Student versions of the course notes (which may contain gaps to be filled in during the lectures) will be made available on Learn prior to the start of each new module. In addition, paper copies of each module will be handed out in class at the beginning of each new module. Master versions of the notes (will all gaps filled in) will not be made available. However, lecture recordings will be available. Therefore, if you miss a lecture it is your responsibility to catch up on the notes from a classmate or using the lecture recordings.

Tutorial material: Tutorial material will sometimes be made available on Learn, depending on the format of the tutorial. You will get the most benefit from tutorials if actually you will attend them. We will often go over past exams and assignment questions.

Assignments: Assignment question sheets will be made available on Learn at around the same time they are hand out in the class. Assignment solutions will be posted on Learn shortly after the submission date. You should make copies/scans of all your assignments prior to submitting them for assessment.

Technical questions: For technical questions related to course content (lectures and tutorial material, assignment questions etc.) please speak to the lecturer for the relevant module during their scheduled office hours or tutorial sessions. In general, technical questions will not be answered by email as there is potential for confusion. Instead, please arrange to speak to the lecturer in person.

Administrative and other queries: Please direct any other administrative questions to the Course Coordinator, Dr Gabriele Chiaro.

Assessment

Assessment Due Date Percentage 
final exam 60%
test 15%

• A minimum 50/100 marks must be achieved in the course (summing up the marks of the final exam, assignments and lab reports).
• A minimum mark of 40% must be achieved in the end-semester exam in order to pass the course. All modules from the course are examinable.

Additional Course Outline Information

Special Considerations

Any student who has been impaired by significant exceptional and/or unforeseeable circumstances that have prevented them from completing any major assessment items, or that have impaired their performance such that the results are not representative of their true level of mastery of the course material, may apply for special consideration through the formal university process. The applicability and academic remedy/action associated with the special consideration process is listed for each assessment item below. Please refer to the University Special Consideration Regulations and Special Consideration Policies and Procedures documents for more information on the acceptable grounds for special consideration and the application process. Current University guidelines state that special considerations must be assessed as severe or serious to justify missing a test or exam. Students who do not meet this criterion will be given a score of zero.

Special Consideration for Assignments
An extension will be granted for evidence-supported requests. Extensions will typically be for up to one week, but the duration will be considered on a case-by-case basis. Students seeking an extension must contact the course coordinator as soon as possible with evidence of their situation, and preferably before the due date.

Special Consideration for Mid-term Test
• The marks for students with special consideration assessed moderate or higher will be adjusted based on their performance in the final exam.
• Students who are unable to sit the test due to exceptional and/or unforeseeable circumstances will be offered an equivalent alternative test close to the original test.



Special Consideration for Final Exam

• Students with special consideration assessed moderate or higher will be offered an equivalent alternative exam that will replace their original exam mark. This exam will be held close to the exam period. Dates will be advertised in due course.
• Students who are unable to sit the final exam due to exceptional and/or unforeseeable circumstances will be offered an equivalent alternative test close to the original test. See comment about severity scores.


Note: All communication associated with the arrangement of equivalent alternative tests/exams will be conducted using official UC email accounts. The offer to sit an alternative assessment will come with a list of potential dates/times. Students will have a clearly specified amount of time to respond to the offer to sit the alternative assessment and accept one of the listed dates/times. If the offer is declined or no response is received in the specified time frame, the original assessment mark will be used to compute the course grade.
