DEEP FOUNDATIONS AND EARTH RETAINING STRUCTURES - 2022/3
Module code: ENGM272
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.
Civil engineers are often called on to design systems that will support large structures at depth or steep / vertical faces in soil. The former case will normally require large foundations, sometimes at depth whereas the latter may require an earth-retaining structure of some kind. Ground modifications techniques are often employed to improve the physical properties of ground before construction begins. This module applies the basic principles of soil mechanics to the safe and sustainable design of large foundations and earth-retaining structures.

Number of Credits: 15
ECTS Credits: 7.5
Framework: FHEQ Level 7
JACs code: H250
Module cap (Maximum number of students): N/A
Prerequisites / Co-requisites
A knowledge of basic soil mechanics and structural mechanics to FHEQ Level 6.
Indicative content includes:
- Overview of foundation design
Flow chart and basic ingredients for foundation design, summary of soil parameters and soil testing required, engineering correlations for obtaining soil parameters
- Design of shallow foundations (carrying moments) and deep foundations
Bearing capacity for shallow foundations with large moments, types of pile foundations and the method of construction, Bridge foundations and design considerations under special conditions (seismic areas), geotechnical bearing capacity of piles (shaft resistance and end bearing using API Code), Structural capacity of piles, Eurocode provisions, settlement calculations, analysis of laterally loaded piles (p-y, t-z, q-z), Stiffness of piles and caissons, Analysis of caissons supporting bridges
- Earth-Retaining Structures
Limit states for design, General Wall selection (sheet pile, secant piles, contiguous piles, diaphragm wall), Practical design issues, Case histories
- Ground Improvement:
Requirements for ground improvement, ground improvement techniques widely used in practice: principles on each type of ground improvement methods and their suitability, case studies on ground improvement methods.
|Assessment type||Unit of assessment||Weighting|
The assessment strategy is designed to provide students with the opportunity to demonstrate
· Knowledge and understanding of the principles of deep foundation and earth-retaining structure design (LOs 1-5) – assessed through a 2-hour unseen examination.
· The ability to solve open-ended design problems using real data (LOs 3, 5) - assessed through coursework assignments.
Thus, the summative assessment for this module consists of:
· Foundation design coursework due Week 8 of Semester 2
· Examination (2 hours, closed book)
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.
- understanding the overview of foundation design through the use of generic flowchart and the required basic ingredients
- understanding of the failure mechanisms for foundations and earth-retaining structures through Limit States
- ability to carry out analysis and design of foundations (deep foundations for complex applications, shallow foundations with large moments) using different codes of practices.
- understanding of some fundamental design issues through case studies and assignment work
- understanding of some design and analysis issues for foundations (to provide an appreciation of the issues related to foundation construction)
- knowledge and understanding of design and the need for site investigation
- an overview and broader understanding of ground improvement techniques including design methodologies

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
Build on students’ knowledge of geotechnical engineering and help them to apply it to the design and analysis of deep foundations and earth-retaining structures.
The learning and teaching methods include:
- combined lectures/problem-solving/software demonstration classes (3hrs per week for 11 weeks = 33hrs)
- independent learning (reading, tutorials, using software, coursework assignments, and revision) (115hrs)
- unseen written examination (closed book) (2hrs)
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.
