CEG8204 : Ground Improvement Techniques

Semester 1 Credit Value: 10
ECTS Credits: 5.0


To introduce students to the concepts underpinning a range of ground improvement techniques and an appreciation of how these techniques are applied in practice.

The module will provide an introduction to a range of ground improvement techniques; the principles behind how the techniques 'work', for which soils they are appropriate and how they are installed or constructed. Where relevant, the principles of design are introduced.

Outline Of Syllabus

Mechanical methods (compaction, explosives, vibroflotation, vibroreplacement). Hydraulic methods (groundwater lowering, preloading, electro-osmosis). Physical/chemical methods (admixtures, grouting, freezing). Inclusions (geosynthetics, reinforcements).

Teaching Rationale And Relationship

Underpinning concepts are explained in lectures. Examples of applications of the techniques provided by industry speakers augmented by videos. Presentations and worked examples help students identify appropriate techniques for different situations. Visiting speakers from industry will provide practical relevance and case study examples of a selection of the techniques; laboratory classes and/or field visit(s) will reinforce principles of operation and/or design and installation methods.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The exam covers the complete syllabus in section 1, which is compulsory and is intended to assess the understanding of the principles behind all the methods covered in the syllabus. A choice is offered in section 2 and includes open ended questions in which the student has to identify the problems and select suitable ground engineering techniques to provide a rational solution thus demonstrating ability to select appropriate method(s) for a select soil type(s).
