A knowledge of basic soil mechanics and structural mechanics to FHEQ Level 6.

Module overview

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.

Module aims

awareness of modern earth-retaining structures and associated construction techniques

understanding of the failure mechanisms for earth-retaining structures

knowledge of design methods for some specific earth-retaining structures

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)


 

Assessment Strategy

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 6 of Semester 2

·         Earth-retaining structure 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.
