DESCRIPTION - summary of the module content

A good knowledge of the philosophies and techniques of geotechnical design and analysis are essential elements of the training of civil engineers, and this module will give you a useful grounding in these important topics. You will get the chance to interpret geological features in the field and gain experience of field observation and measurement techniques, site investigation and preliminary design of a civil engineering structure. Furthermore, you will develop essential awareness of ground conditions and general safety on civil engineering sites. Finally, you will learn how to assess stresses in the soil mass, bearing capacity and  settlement of shallow and deep foundations, stability of gravity and embedded retaining walls and stability of slopes.


Prerequisite module: ECM2110 or equivalent

AIMS - intentions of the module

To introduce you to the techniques of geotechnical design and analysis and their limitations, the underlying philosophies of current geotechnical practice, and different practical applications in civil engineering projects, such as the design of foundations, the design of retaining walls and the stability of slopes.

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.

If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
