Description

This module is an introduction to Soil Mechanics & Geology, assuming no prior knowledge of the subject. The student starts with the formation and origin of rocks and the processes which result in the formation of soil before learning how these processes influence soil behaviour due to external loading or the flow of fluid through the soil.

Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Identify and classify soils and rocks and calculate their phase relations. Describe how rock and rock structures are formed and weathered.

2.

Compute coefficients of permeability from standard laboratory tests and compute critical hydraulic gradients.

3.

Calculate total stress, effective stress and porewater pressure and evaluate the shear strength parameters of the soil in drained and undrained conditions. Calculate lateral earth pressures.

4.

Estimate one-dimensional settlements in soils.

5.

Use standard laboratory equipment and perform as a team member in the execution, compilation, analysis and interpretation of laboratory experiments

6.

Compile and report, in both written and oral form, using word and excel, the results and conclusions of laboratory work

Module Assessment Strategies

1. 1 hour MCQ exam mid-semester

2. 2 hour written final exam

3. Laboratory practical copy and oral presentation
