Geotechnics - 2021 entry

In this module you will study the behaviour of rock and soil used for the purposes of man’s utilisation. It is  suitable for students who wish to build upon their geological and/or other technical knowledge gained in first year courses in a practical way to enable you to learn about the design of structures constructed of, or within rocks and soils. It is suitable for non specialised students with a good level of numeracy. The module is taught using lectures, group exercises at the CSM test mine and practical work in the CSM geomechanics laboratory. There will be two assignments during the academic year which are: Report of the rock laboratory tests and Rock mass classification.

A prerequisite is a completion of CSM first year modules or possible direct entry second year candidates.

This course is recommended as a gateway to various disciplines such as the civil engineering, mining and minerals engineering, surface and underground construction and environmental fields with, for example, structures such as the channel tunnel, large scale dams and open pit mines requiring geotechnical expertise to enable safe design.

By the end of this module you should understand the different rock and soil models commonly used in geotechnical engineering and have acquired the analytical and mathematical skills required for geotechnical modeling and design.

The module provides an introduction to the engineering description of rock, rock mass classification and applied rock engineering and includes the engineering description of soil, soil classification and a basic knowledge of site investigation practice and principles.  The module develops problem solving skills, team-working skills and provides simulated industrial experience in the CSM test mine, providing an opportunity for students to design the reinforcement requirements for an underground excavation based on their own field mapping data.

On successful completion of this module, you should be able to:
