Postgraduate

CEG8210 : Soil Mechanics and Ground Characterisation

Semesters
Semester 1 Credit Value: 20
ECTS Credits: 10.0

Aims

The aim of this module is to introduce the basic skills and knowledge required by an engineering geologist or geotechnical engineer. Specifically, the module aims:

Students should be able to demonstrate their knowledge and understanding of essential facts, concepts, theories and principles of ground engineering in designing a ground investigation.

Students should be able to demonstrate an ability to organise a desk study and site reconnaissance to assemble data to design a ground investigation and construct an engineering ground model

Students should be able to understand risk assessment and methods in the context of ground investigations.


Students should be able to understand the key numerical concepts and principles in mechanics of soils that will allow them to proceed at a later stage to geotechnical design.

Students will be introduced to critical state theory and numerical and physical modelling techniques in geotechnical design.

Summary:

This module will provide an introduction to the engineering properties of soils and rocks as well as the design and philosophy of geotechnical site investigations and their relevance to geotechnical design. Students will learn about the range of exploration and testing techniques available to geotechnical engineers. Students will perform standard laboratory practical in soil and rock description and classification.

Students will be introduced to the range of Earth materials and structures that may be encountered in engineering geology and geotechnical engineering, and (b) enhance their knowledge and understanding of the engineering behaviour and properties of these materials and structures and their impact on geotechnical design case studies.

Outline Of Syllabus

*Introduction to ground investigation and objectives

*Desk Study: Site reconnaissance, requirements, and legislation including contaminated land; Design of a ground investigation;

*Exploration techniques: Shallow and deep exploration techniques; Sampling techniques: In Situ tests, field permeability tests, geophysical tests, and pressuremeter test

*Laboratory Testing and fundamental principles: Basic characteristics of soils and rocks, laboratory sampling, particle size and shape distribution; Permeability, consolidation and shear strength; Students will undertake standard soil testing procedures, including determination of Atterberg Limits, PSD, permeability, shear strength parameters, compaction and consolidation properties.

*Reporting and Ground Models: Factual and interpretative reporting; Bill of quantities, Risk assessment, development of a ground model

*Application: Effective stress; Seepage of water and flow nets; Calculation of settlement; Introduction to critical state theory; Introduction to physical and numerical modelling Ground investigation in Contaminated Land environments, requirements, and legislation

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

Mechanical and mathematical knowledge is delivered through formal lecture classes supported by practical exercises. Practical skills such as soil description are developed through practical classes. Students are expected to acquire knowledge and understanding through reflection on taught material and through undertaking independent learning. Students acquire practical skills through active participation in the practical class exercises and field work.

Alternatives will be offered to students unable to be present-in-person due to the prevailing C-19 circumstances.
Student’s should consult their individual timetable for up-to-date delivery information.

Assessment Rationale And Relationship

Each student will submit an electronic site investigation report summarising the results of desk study and laboratory tests. The data will be interpreted to produce a ground model and discussion on site condition. They will also be assessed through the recommendation for further investigation and its costing.

Students’ acquisition of knowledge and understanding of fundamentals are assessed through a written examination.
