Virtually all civil engineering structures are in contact with the ground. Sometimes the ground exerts a force to be carried by the structure (e.g. retaining walls, tunnels), or provides a reaction which helps support the structure (e.g. a foundation). In some cases the ground is the structure and must be designed to support itself (e.g. embankments and slopes). This module deals with the latter two categories and applies the basic principles of soil mechanics to the safe and sustainable design of foundations and soil slopes.
Provide students with basic analytical tools for designing both shallow and deep foundations, cut slopes and embankments – satisfying relevant stability and deformation criteria, and distinguishing between short and long-term conditions
Impart an understanding of why foundations and slopes become unsafe, what the possible consequences are, and how the risk of failure can be managed
Introduce relevant site investigation and in-situ testing methods for identifying ground conditions and determining geotechnical parameters for design purposes
Provide students with an understanding of some fundamental design issues through case studies and assignment work.
Provide students with an understanding of health and safety, and of sustainability issues in foundation and slope design and construction.

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
Build on students’ knowledge of soil mechanics acquired in FHEQ Level 5 and help them to apply it to the design and analysis of foundations and slopes. The module forms part of the key theme of Geotechnical Engineering which runs through all Levels on BEng and MEng programmes in Civil Engineering.
The learning and teaching methods include:
Combined lectures/problem-solving classes on foundations(2hrs per week for 11 weeks)
Combined lectures/problem-solving classes on soil slopes(1hr per week for 11 weeks, plus 3 additional 1hr slots for tutorials)
Independent learning (reading, tutorials, coursework assignments, and revision) (112hrs)
Unseen written examination (closed book) (2hrs)
The assessment strategy is designed to provide students with the opportunity to demonstrate the following:
1/ The ability to choose appropriate strength parameters (LO8) and drainage conditions and carry out the necessary computations using the most appropriate method in order to assess the stability of a slope in soil (i.e. fill or cut slope) (LO6) is assessed principally through a coursework assignment. The assignment also calls for issues of drainage (LO7) sustainability (LO9), risk (LO10) to be considered in the context of suggestions for improvements to the design slope given. The examination focuses on testing those aspects of LOs 6, 7 and 8 not fully covered by the coursework assignment.
2/ The ability to choose appropriate strength parameters (LO8) and drainage conditions and carry out the necessary computations to assess the load bearing capacity and settlement of a foundation (shallow or deep) (LO1, 2, 3, 4, 5) is assessed principally through a coursework assignment. The assignment also calls for issues of sustainability (LO9) and risk (LO10) to be considered in the context of the overall foundation design, and suggestions for improvements to it. The examination focuses on assessing those aspects of LOs 1-5 not fully covered by the coursework assignment.
Thus, the summative assessment for this module consists of:
· Soil slope stability coursework [Learning outcomes assessed 6, 7, 8, 9, 10, a, b, c, d] (12 hours, 8%)
· Foundation design coursework [Learning outcomes assessed 1, 2, 3, 4, 5, 9, 10, a, b, c] (18 hours, 12%)
· Examination (2 hours, closed book, 80%)
Formative assessment and feedback
Feedback will be given on both coursework assignments, in the form of generic comments through SurreyLearn and more detailed and individualised feedback given on the marked assignments within the time allowed for marking coursework. Formative assessment will be through solving problems in class (and getting feedback on the correct solution there and then) and also through tackling tutorial sheets – for which feedback takes the form of full worked solutions posted on SurreyLearn after the student has had an opportunity to try the problems for him/herself.
