Sample subject outline - Semester 2 2013
Note: Subject outlines often change before the semester begins. Below is a sample outline.
Rationale
Geomechanics (soil mechanics and rock mechanics) and their application to geotechnical engineering is one of the most important areas of study for civil engineers. It is concerned with the use of soil and/or rock as an engineering material and includes a wide range of activities such as: site investigation and soil/rock classification, material selection, design of foundations for building, bridges, and other structures, design and construction of dams, road pavements, embankments, tunnel excavation and supports, and slope stabilisation.
This is the second of two compulsory units and one elective unit, covering the field of foundation and rock engineering, which requires basic engineering mechanics knowledge gained from ENB110 (Static & Materials) and Mathematics knowledge gained in the first year and fundamental geotechnical knowledge from second year, ENB272 (Geotechnical Engineering 1).
Aims
The aim of this unit is to develop your knowledge and skills of the application of geotechnical theory in the design of shallow and deep foundations. You also will learn theory of rock engineering and their application in analysing the stability of rock slopes.
Objectives
On completion of this unit you should be able to:
1. Explain and apply geotechnical theory to solve practical geotechnical problems
2. Calculate engineering properties of soil
3. Design of shallow foundations using appropriate theory and soil properties
4. Design deep foundations using appropriate theory and soil properties
5. Explain and apply rock mechanics theory to calculate the stability of rock slopes
6. Measure engineering properties of soils conducting appropriate laboratory tests being a member of a student group and present the finding in a report
Content
Topics to be covered:
- Stress distribution and elastic settlement in soil
- Consolidation theory and settlement calculation
- Design of shallow foundation
- Design of deep foundation
- Theories of rock engineering and their application for the stability of rock slopes
Approaches to Teaching and Learning
Teaching Mode: 5 hrs per week plus 1 prac session
Lecture: 3 hrs
SI Tutorial: 2 hr
Pracs: 1 x 2 hrs (Week 6/8).
Written reports should be submitted within two weeks after prac class.
Lectures provide the key theoretical principles and concepts illustrated with significant examples. In tutorial class you will work through practical applications and problem solving techniques with lecturer/tutor guidance and class discussion. In practical laboratory sessions, you will work in small groups to integrate theory with practice by 'real' testing of lab soil samples and structures. Use of geotechnical methods, software and group work will give you real 'test and report' experiences similar to industry requirements. The final exam will involve problem solving key concepts, techniques and solutions from across the semester.
Assessment
Assessment will be based on one online quiz covering the first half of semester work (opened book, two attempts), two laboratory group reports and a final exam. Formative assessment will include a first attempt at the online quiz as well as a 'practice exam' with opportunity for feedback.You will receive ongoing oral feedback throughout the semester in lab and tutorial class discussions. To assist learning and feedback opportunity, you are encouraged to submit the online quiz and get feedback on any areas of difficulty from the lecturer before submitting a second time. Similarly, you will have opportunity for group and tutor/lecturer discussion of your lab report prior to submission with written feedback afterwards to assist with the second lab report. You are also encouraged to seek oral feedback from lecturer and other students after completing a 'practice exam' via the unit website. Criteria sheets about the final exam will be available on the unit website and feedback will also available on request after the exam results are published.
Assessment name:
Problem Solving Task
Description:
Finite number of online multiple choice questions should be completed in restricted time span in Week 9. The task is non-invigilated, open book, and permitted two attempts with feedback on request in between. The task is based on week 1-8 lecture content.

Risk assessment statement
Students in this unit will undertake lectures and tutorials in the traditional classrooms and lecture theatres. Therefore, there are no extraordinary workplace health and safety issues associated with these components of the unit.
Students will be required to undertake practical sessions in the laboratory under the supervision of the lecturer, tutors, and technical staff of the school. The school's occupational health and safety policies and procedures will apply to these sessions. It is recommended for students to wear steel-cap boots in attending laboratory practical sessions
