DESCRIPTION - summary of the module content
In this module you will study the engineering 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 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.
 
There will be two assignments during the academic year which are: 1) A Rock mass classification and support design assignment and 2) a soils or permeability assignment.
 
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.
 
AIMS - intentions of the module

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, and provides simulated industrial design experience, providing an opportunity for students to design the reinforcement requirements for an underground excavation based on field mapping data.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module, you should be able to:
 
Module Specific Skills and Knowledge:
1 appreciate both rock and soil behaviour in the context of the geotechnical and related industries;
2 describe and classify an engineering soil or rock;
3 design a basic site investigation programme and understand the standard site investigation tests and their uses;
4 recognise the influence of factors controlling the engineering behaviour of a rock or soil;
5 understand rock engineering in the context of the geotechnical and related industries;
6 visualise discontinuity data using stereograms;
7 perform rock mass mapping and apply empirical design methodology;
8 comprehend the influence of factors controlling the engineering behaviour of rock masses;
 
Discipline Specific Skills and Knowledge:
9 use relevant information and understand its influence on engineering behaviour of rock or soil;
10 evaluate and apply knowledge of a range of different concepts relating to material behaviour;
11 apply this knowledge to a variety of design applications;
 
Personal and Key Transferable/ Employment Skills and Knowledge:
12 manage learning using resources for the discipline; an ability to develop working relationships of a professional nature within the discipline;
13 interact effectively within a team/learning group, giving and receiving information and ideas and modifying responses where appropriate;
14 select appropriate data from a range of sources and develop research strategies;
15 identify key areas of problems and choose appropriate tools/methods for their resolution in a considered manner.
