GEOTECHNICAL ENGINEERING - 2022/3
Module code: ENG3175
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
Virtually all civil engineering structures are in contact with the ground. Sometimes the ground exerts a force which must be carried by the structure (e.g. retaining walls, tunnels), or provides a reaction which helps support the structure (e.g. through a strip footing or a piled raft). In some cases the ground is the structure and must be designed to support itself (e.g. embankments and cuttings). 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.

ECTS Credits: 7.5
Framework: FHEQ Level 6
JACs code: H250
Module cap (Maximum number of students): N/A
Prerequisites / Co-requisites
The module is divided into two main parts - foundation engineering and soil slope stability - which are taught in parallel.
Foundation Engineering includes the following topics:
- Foundation types and construction methods
- Limit states, safety, and drainage conditions
- Bearing capacity of shallow and piled foundations
- Stress distributions, theory of elasticity
- Settlement of shallow and piled foundations
- Sustainability in foundation design
- Practical design issues and case histories
Soil Slope Stability includes the following topics:
- Slope types, limit states and drainage conditions
- Planar, circular and non-circular failure mechanisms
- Force and moment equilibrium
- Total and effective stress analysis
- Practical design issues
Site Characterization is relevant to both of the above and includes:
- Exploration and sampling
- In-situ testing
- Interpretation of test data
This module is within the core subject of Geotechnics, and the threads of Design (especially foundations and soil slopes), Health and Safety Risk Management, and Sustainability (especially in the coursework assignments).
|Assessment type||Unit of assessment||Weighting|
|Coursework||COURSEWORK - FOUNDATION DESIGN AND SLOPE STABILITY||25|
|Examination||EXAMINATION (2 HOURS)||75|
The assessment strategy is centred on two units of assessment.
- The coursework assignment assesses the ability to choose appropriate strength parameters and drainage conditions, and carry out the necessary computations to assess the load bearing capacity and resultant settlement of a foundation, and the stability of an adjacent soil slope. The assignment also calls for issues of risk and sustainability to be considered in the context of the overall design (Learning outcomes 001, 002, 003, 004, 005, 006, 007 and 008).
- The end-of-semester examination provides students with the opportunity to demonstrate their understanding of fundamental concepts in the analysis and design of soil slopes and foundations, focussing on assessing those aspects not fully covered by the coursework assignments (Learning outcomes 001, 002, 003, 004, 005, 006, and 007).
Feedback will be given on the coursework assignment, in the form of generic comments through SurreyLearn and more detailed and individualized feedback given on the marked assignments. Formative assessment will be through solving problems in class (and receiving immediate feedback on the correct solution) 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.
- 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

Overall student workload
Independent Study Hours: 114
Lecture Hours: 36
Methods of Teaching / Learning
The module is delivered principally through combined lectures / problem-solving classes, supported by independent learning (reading, tutorial sheets, coursework assignments, and revision). It builds on students’ knowledge of geology and soil mechanics acquired in FHEQ Levels 4 and 5 and helps them to apply it to the design and analysis of foundations and soil slopes.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
