Undergraduate Course: Geotechnical Engineering 2 (CIVE08025)
|School||School of Engineering
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 8 (Year 2 Undergraduate)
||Availability||Available to all students
|Summary||This course introduces soil mechanics and engineering geology for geotechnical engineering applications such as foundations, rail construction and tunnels. It considers the fundamental mechanics of soils as a heterogeneous mixture of air, water and solid particles and the origin of these materials from their parent rocks. It analyses the deformation of natural and man-made structures that comprise or are built upon soil, and the flow of fluids within them. It develops an understanding of how the fundamental principles of geological sciences influence the design and construction of engineering structures.
The course covers the fundamental multi-phase nature of soils and their origins, soil and rock description and classification, the effective stress concept, elementary seepage and compaction problems, and the standard soil testing techniques for analysing and determining soil properties.
Aims and challenges of geotechnical engineering; Introduction to Engineering Geology, Rock Mechanics and Soil Mechanics
Structural Geology; Geohazards & Earthquakes; Difficult Grounds; Ground Investigation
Soil and rock types:
Nature and formation of soils/rocks; Description and Classification of soils/rocks; Rock-quality designation
Multi-phase nature of soils:
Mass-volume relationships; Soil phase diagram; Theory of compaction; Laboratory compaction tests
Stresses in soils:
Pore-water pressure; Effective stresses; Geostatic stress condition; Horizontal and vertical stresses; Normal consolidation and overconsolidation; Stresses in two dimensions; Mohr's diagram method of stress analysis
Permeability of soils:
Flow of water through soil; Darcy's law; Laboratory measurement of permeability; Field measurement of permeability; One-dimensional seepage; Two-dimensional seepage; Flow net construction and uses in the solution of geotechnical seepage problems.
Tutorials give the students ample opportunities to develop skills in applying the theories and methods learned to solve elementary geotechnical engineering problems. The exercises cover a great variety of elementary geotechnical problems in varying degrees of difficulty:
Mass-volume relationship, soil/rock classification, and compaction
Total and effective stresses, Mohr's circle
Permeability and Seepage
Laboratory classes aim to train the student in proper laboratory test techniques, including the analysis of results and the evaluation of relevant properties.
Laboratory 1 - Determination of plastic and liquid limits:
The experiments to determine the plastic limit and liquid limit of a clay soil are performed in accordance to BS1377:1990. The results lead to the determination of the plasticity index and the use of the plasticity chart.
Laboratory 2 - Compaction, maximum dry density:
The experiment to determine the relationship between dry density and water content is performed in accordance to Test 12 of BS1377:1990. The optimum water content which gives the maximum dry density for a certain compactive effort is determined.
Laboratory 3 - Determination of coefficient of permeability:
The coefficient of permeability of a sand is determined by using a constant head permeameter.
