Overview
Geotechnical Engineering is concerned with the stability analyses of soil structures. Topics covered in this course include soil shear strength, slope stability analysis, retaining wall analysis, shallow foundations, landfill liners and subsoil exploration.
Course learning outcomes
The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:
- understand what is meant by the shear strength of a soil and the implication of loading duration on the measured shear strength of a soil and become familiar with the terminology of 鈥渄rained鈥� and "undrained" loading and procedures involved in various shear strength tests;
- determine lateral earth pressures using Rankine, Coulomb and curved failure surface methods and use this knowledge for the basis of designing earth retaining structures;
- analyse drained and undrained slope stability problems using the method of slices, design charts and computer programs;
- determine the ultimate bearing capacity of shallow foundations and use this knowledge for the basis of designing shallow foundations;
- determine the axial capacity and settlement of pile foundations;
- understand the use of liners and geosynthetics in landfill application;
- understand the processes involved in subsoil exploration.
