Compulsory/Optional : Compulsory

Aim(s)
To provide knowledge of how to conduct geotechnical investigations and analyse geotechnical structures such as slopes, retaining structures and foundations.
Intended Learning Outcomes
On successful completion of the course, the students should be able to; Analyse stability problems of natural and man-made slopes using limit equilibrium and earth pressure theories and propose appropriate remedial measures including internally or externally stabilised retaining structures. Analyse isolated or combined shallow foundations in cohesive and cohesionless soils. Analyse deep foundations in cohesive and cohesionless soils Organize and perform a site investigation programme to select sites suitable for geotechnical construction and to obtain material profile and parameters required for design.
