The 1st Hanrahan Lecture: Geotechnical properties of Irish glacial and interglacial soils
This paper reviews the current state-of-the-art in relation to geotechnical design in unsorted till deposits, commonly called Boulder clays by engineers or diamictons by geologists, generally taking the topics discussed by Prof. Eamon Hanrahan in his seminal work on Irish tills of 1977. These topics include the permeability, stiffness, and consolidation characteristics of these deposits, together with their undrained and drained behaviour. The geological background to the deposition of these tills is discussed and the available information on the presence of interglacial soils around the country is presented. Where possible, the practical experience from working with these deposits is compared with predictions made from field or laboratory test results, for example, in settlement assessment of foundations, slope stability and in earthworks.
Whilst most of Ireland is covered with stony Boulder clays, which is the main topic of the paper, the geotechnical parameters of a fine grained till encountered on the east coast, known as Irish Sea till or colloquially as Macamore Clay, are discussed and the implications of this on slope stability is investigated.
期刊介绍:
Quarterly Journal of Engineering Geology and Hydrogeology is owned by the Geological Society of London and published by the Geological Society Publishing House.
Quarterly Journal of Engineering Geology & Hydrogeology (QJEGH) is an established peer reviewed international journal featuring papers on geology as applied to civil engineering mining practice and water resources. Papers are invited from, and about, all areas of the world on engineering geology and hydrogeology topics. This includes but is not limited to: applied geophysics, engineering geomorphology, environmental geology, hydrogeology, groundwater quality, ground source heat, contaminated land, waste management, land use planning, geotechnics, rock mechanics, geomaterials and geological hazards.
The journal publishes the prestigious Glossop and Ineson lectures, research papers, case studies, review articles, technical notes, photographic features, thematic sets, discussion papers, editorial opinion and book reviews.
