The module aims to introduce the students to basic soil mechanics concepts (fluid flow, consolidation settlement and stress distributions in soil masses), and show how the fundamental principles of Soil Mechanics are applied to simple problems including the stability of slopes and pressures against earth retaining structures.
A. Describe soils, measure their basic properties, and use these to calculate other soil parameters.
B. Calculate approximate stresses and effective stresses at any point below ground level, be able to carry out stress transformations using Mohr’s Circle, and be able to analyse laboratory stress-strain responses
C. Use graphical forms of, Bernoulli equation, Darcy’s Law, Hazens empirical formula, Young’s Equation, and the Laplace Equation during both the prediction and measurement of the interaction between a fluid and soil and on this basis solve 1D, 2D, and 3D fluid-soil interaction problems.
D. Use approximations to assess the engineering stability of inclined soil masses including: moment equilibrium, Taylors friction circle, The Fellenius method of slices, and the use of engineering design curves.
E. Generate engineering designs for shallow foundations taking into account considerations of bearing capacity and laboratory derived consolidation measurements.
F. Suggest appropriate methods by which the engineering properties of the ground can be improved given a wide range of staring materials and engineering projects, and be able to suggest appropriate methods to monitor the grounds post-engineering behaviour.
The lectures are used to teach the background knowledge. Practical classes are used to teach how the real world behaviour of materials relates to the theoretical behaviour.
