CIVL5460: Particle Mechanics for Geotechnics

The objectives of this unit are to demonstrate how the granular structure of soil materials controls their engineering behaviour; translate particle micromechanics to improve macroscopic engineering predictions; and establish the intimate connection of geotechnical engineering to other disciplines where granular materials play a pivotal role, including mining engineering, bulk materials handling, and geophysics. Similarly, this course will cohesively connect geotechnical engineering with fluids engineering principles, as well as enhance students' background in materials science. At the end of this unit students will be able to understand and use Discrete Element Method to evaluate and solve geotechnical problems such as rockfall interactions with surrounding terrain. They will also critically analyse pile penetration and silo discharge in light of granular mechanisms; apply soil rheology to carry out parametric study of landslide flows; and understand and use dimensionless analysis principles to predict resistive forces on obstacles. Strong focus will be dedicated for communicating students' results using written methods appropriate for professional engineers.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Special consideration

If you experience short-term circumstances beyond your control, such as illness, injury or misadventure or if you have essential commitments which impact your preparation or performance in an assessment, you may be eligible for special consideration or special arrangements.

Academic integrity

The Current Student website provides information on academic honesty, academic dishonesty, and the resources available to all students.

The University expects students and staff to act ethically and honestly and will treat all allegations of academic dishonesty or plagiarism seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic dishonesty. If such matches indicate evidence of plagiarism or other forms of dishonesty, your teacher is required to report your work for further investigation.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Required readings〈=en

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University’s graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. Provide clear and well articulated laboratory reports of physical experiments supported by well established theoretical background.
  • LO2. Estimate the bearing capacity of piles in terms of particle crushability and frictional interaction.
  • LO3. Critically understand the applicability of the discrete element method in material bulk handling and geotechnics.
  • LO4. Critically understand the mechanisms dictating fluid forces on granular media, and assess permeability in granular soils.
  • LO5. Evaluate the stresses in silos and explain their effects on their failures.
  • LO6. Determine the effect of particle properties on the shear forces developing along interfaces.
  • LO7. Critically analyse the kinematics of granular landslides using particle rheological equations.

Graduate qualities

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

GQ1 Depth of disciplinary expertise

Deep disciplinary expertise is the ability to integrate and rigorously apply knowledge, understanding and skills of a recognised discipline defined by scholarly activity, as well as familiarity with evolving practice of the discipline.

GQ2 Critical thinking and problem solving

Critical thinking and problem solving are the questioning of ideas, evidence and assumptions in order to propose and evaluate hypotheses or alternative arguments before formulating a conclusion or a solution to an identified problem.

GQ3 Oral and written communication

Effective communication, in both oral and written form, is the clear exchange of meaning in a manner that is appropriate to audience and context.

GQ4 Information and digital literacy

Information and digital literacy is the ability to locate, interpret, evaluate, manage, adapt, integrate, create and convey information using appropriate resources, tools and strategies.

GQ5 Inventiveness

Generating novel ideas and solutions.

GQ6 Cultural competence

Cultural Competence is the ability to actively, ethically, respectfully, and successfully engage across and between cultures. In the Australian context, this includes and celebrates Aboriginal and Torres Strait Islander cultures, knowledge systems, and a mature understanding of contemporary issues.

GQ7 Interdisciplinary effectiveness

Interdisciplinary effectiveness is the integration and synthesis of multiple viewpoints and practices, working effectively across disciplinary boundaries.

GQ8 Integrated professional, ethical, and personal identity

An integrated professional, ethical and personal identity is understanding the interaction between one’s personal and professional selves in an ethical context.

GQ9 Influence

Engaging others in a process, idea or vision.
