Coursework Policies
1. All coursework submitted must include
a. a copy of the full brief given by the module leader (with the signed coversheet)
b. all source material must be cited in the text and a full bibliography of source material (including author, title, publisher and date) listed at the end of the submission
2. All work must be submitted in the mode instructed by the module leader.
3. Work submitted under the student’s name must only be the work of that student. All information sources must be acknowledged. Plagiarism is a serious offence and will render offenders liable to disciplinary action as set out in the Kolej Universiti Linton (and parent university) rules and regulation.
4. Students MUST keep a copy of all submitted work for reference purposes prior to the original being handed in and returned. This will provide proof that the work was completed, in the event that the work goes astray.
4. Coursework received after the submission deadline without an authorised time extension will be marked if submitted within two weeks of the initial deadline. However, the mark awarded will be the minimum (40%). Where the quality of work is below a pass level (i.e. 40%), a mark of 0-39% will be awarded as appropriate.
5. Whenever a candidate submits work after two weeks without an authorised extension, a mark of zero (0%) will be awarded. Examiners may comment on the quality of the work for learning purposes.
6. Requests for extensions of submission deadlines must be made in writing prior to the submission deadline to the module leaders and must be supported by documentary evidence.

ASSIGNMENT BRIEF
Learning Outcomes:
LO1. Appraise, identify and prioritise the geotechnical properties that are pertinent to a given practical problem
LO2. Conceptualise, analyse and evaluate the states of stress and strain in a soil element within a geotechnical structure in order to communicate the stress/strain paths for assessing its stability
LO3. Critically identify the different mechanisms of ground movement
LO4. Collaborate and perform desk analysis for the stability of soil slopes
LO5. Apply quantitative methods and software packages to the solution of geotechnical problems
LO6. Present analysis and design calculations
Highlighted Information:
1. This assignment is an individual work
2. Your response to this summative assignment is worth 25% of the total module mark
3. Computer discs to be attached to the work in an envelope or purpose made sleeve adhered to the rear
4. Harvard Referencing method is mandatory. ALL material gathered from other sources and presented for assessment in the assignment must be referenced
5. You are reminded of the school policy on late submissions of coursework and on any hint of plagiarism
Advice on Sources of Information:

Instruction:
You need to download the GRETA (geotechnical software from Oasys Ltd.) made available for limited student use. You must demonstrate the use of it in the analysis. It is advised that you read relevant texts in relation to the slope stability analysis.
TASK 1
FIGURE 1 shows the cross-section of a proposed highway cutting in a homogeneous clay soil. Determine the factor of safety in term of effective stress using:
a) Fullenius’ method (hand calculation & Slope program)
b) Bishop’s method (hand calculation & SLOPE/W program)
[40%]
TASK 2
Critically discuss the validity of all your answers in Task 1.
[20%]
TASK 3
Using the same parameters as from Task 1, compare and contrast the outputs of analysis based on the Bishop’s method using three different slip surface shapes of your choice.
[20%]
TASK 4
Using the same parameters as from Task 1, suggest an appropriate stabilisation method and evaluate the improvement on the overall factor of safety.
