Unit of study_

# CIVL2410: Soil Mechanics

## Overview

This course provides an elementary introduction to Geotechnical Engineering, and provides the basic mechanics necessary for the detailed study of Geotechnical Engineering. This course aims to provide an understanding of: the nature of soils as engineering materials; common soil classification schemes; the importance of water in the soil and the effects of water movement; methods of predicting soil settlements, the stress-strain-strength response of soils, and earth pressures.

### Unit details and rules

Unit code CIVL2410 Civil Engineering 6 None None None CIVL2201 AND GEOL1501 AND (CIVL1802 or ENGG1802). An understanding of simple statics, equilibrium, forces and bending moments, and of stress and strain and the relationship between them. This is covered by University of Sydney courses CIVL1802 Statics (or ENGG1802 Engineering Mechanics), CIVL2201 Structural Mechanics. Familiarity with the use of spreadsheets (Excel, Mathcad) to obtain solutions to engineering problems, and with the graphical presentation of this data.

### Assessment summary

• Quiz: In-class exercises are used to assess students’ understanding of key concepts each week. Best 10 out of 12 will be taken.
• Pre-lab Quizzes: Pre-laboratory online material is to be read before the sessions and each laboratory is preceded by an online quiz.
• Lab Report: Lab reports will address student development in their presentation and analysis skills. Students are expected to present a professional documentation of their experiments and analysis associated with the concepts learned within this UoS.
• Computing Assignment: This assignment is designed to reinforce theoretical concepts and develop the students` skills in the use of Excel. There are two parts to this assessment; part 1 is to develop a spreadsheet to solve a design problem, and part 2 is to write a report describing the outcomes of the design exercise.
• Final Exam: The examination at the end of the semester will measure students’ understanding of the concepts covered during the whole semester. Students need 45% to pass the unit.

Detailed information for each assessment can be found on Canvas.

### 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.

For more information see guide to grades.

### 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.

### Academic integrity

The Current Student website  provides information on academic integrity 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 integrity breaches seriously.

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

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

## Learning support

### Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

### Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

### Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

### Attendance and class requirements

The scheduled lecture on Tuesdays is mostly a tutorial and each week finishes with a short quiz. Attendance is needed to succeed at the quiz

Attendance at scheduled laboratory classes is compulsory

Attendance at weekly 1 hour tutorial sessions are compulsory

### 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.

## Learning outcomes

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. demonstrate proficiency in handling experimental data, including strength parameters
• LO2. analyse and report the results of a laboratory experiment at a professional standard
• LO3. develop and use a spreadsheet to analyse a geotechnical design problem
• LO4. give an engineering classification of any piece of soil, and on this basis predict how it will perform as an engineering material
• LO5. calculate the settlements, and rates of settlement, under structures of various shapes and sizes
• LO6. explain the advantages and limitations of the different methods of settlement calculation
• LO7. determine the strength parameters appropriate to a range of stability problems, and understand the difference between total and effective stress approaches
• LO8. understand the principle of effective stress, and be able to apply this to calculate the stresses causing soil deformation
• LO9. calculate quantities of water flowing through the ground, and understand the effects that water flow has on the soil.

### 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.
