Description

The module looks at permeability, soil strength, consolidation and lateral earth pressures in a soil mas.

Learning Outcomes

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

1.

Define, quantify and formulate the concept of effective stress in geotechnical engineering problem.

2.

Use graphical and computational techniques to determine seepage quantities and pore pressures and to assess the stability of soil masses subjected to seepage forces.

3.

Analyse the strength characteristics of saturated soil.

4.

Formulate and apply consolidation theory to estimate settlement rates and amounts.

5.

Describe, formulate and implement critical state theory to model the behaviour of soi.

6.

Use standard engineering laboratory equipment to perform experiments in teams, observe and record data and experimental evidence.

7.

Design, implement and analysis experimental methods in the soil mechanics laboratory.

Teaching and Learning Strategies

This module will be delivered to full‑time learners through a mix of formal lectures and practical classes.  

Module Assessment Strategies

This module is 30% continuous assessment, consisting of individual practical write‑ups, and 70% final examination at the end of the semester.  

Repeat Assessments

Where a learner fails the continuous assessment element of the module they will be required to resubmit the practical reports for assessment at the repeat examination session.

Learners who fail the end of module terminal examination will have the opportunity to resit the examination during the repeat examination session.
