At some time 30% of the world’s land mass was covered by glaciers leaving substantial deposits of glacial soils under major conurbations in Europe, North and South America, New Zealand, Europe and Russia. For instance, 60% of the UK has been affected, leaving significant glacial deposits under major conurbations where two thirds of the population live. Glacial soils are composite soils with significant variations in composition and properties and are recognised as challenging soils to deal with. Understanding the environment in which they were formed and how this affects their behaviour are critical because they do not always conform to classic theories of soil mechanics. This book is aimed at designers and contractors working in the construction and extractive industries to help them mitigate construction hazards on, with or in glacial deposits. These soils increase risks to critical infrastructure which, in the UK includes the majority of the road and rail network, coastal defences such as the fastest eroding coastline in Europe and most of the water supply reservoirs. It brings together many years of experience of research into the behaviour of glacial deposits drawing upon published and unpublished case studies from industry. It draws on recent developments in understanding of the geological processes and the impact they have upon the engineering properties, construction processes and performance of geotechnical structures. Unlike other books on glaciation it brings together all the relevant disciplines in earth sciences and engineering to make it directly relevant to the construction industry.

The Engineering Group of the Geological Society Working Party brought together experts in glacial and periglacial geomorphology, Quaternary history, engineering geology and geotechnical engineering to establish best practice when working in former glaciated and periglaciated environments. The Working Party addressed outdated terminology and reviewed the latest academic research to provide an up-to-date understanding of glaciated and periglaciated terrains. This transformative, state-of-the-art volume is the outcome of five years of deliberation and synthesis by the Working Party. This is an essential reference text for practitioners, students and academics working in these challenging ground conditions. The narrative style, and a comprehensive glossary and photo-catalogue of active and relict sediments, structures and landforms make this material relevant and accessible to a wide readership.

Bridges the Gap between Geology and Ground Engineering High-quality geological models are crucial for ground engineering projects, but many engineers are not always at ease with the geological terminology and analysis presented in these models, nor with their implications and limitations. Project engineers need to have a sound comprehension of the geological models presented to them, and to be able to discuss the models in so far as they might impinge on the design, safety and possible budgetary or time constraints of the project. They should also fully understand how site investigation data and samples are used to develop and substantiate geological models. Geology for Ground Engineering Projects provides a comprehensive presentation of, and insight into, the critical geological phenomena that may be encountered in many engineering projects, for example rock contact relationships, weathering and karst phenomena in tropical areas, composition of fault zones and variability of rock discontinuities. Examples are provided from around the world, including Southeast Asia, Europe, North and South America, China and India. Comprehensive and well-illustrated, this definitive book: Describes the important geological phenomena that could affect ground engineering projects Provides a practical knowledge-base for relevant geological processes Addresses common geological issues and concerns Rocks are described in relation to the environment of their formation, highlighting the variation in composition, distribution and geotechnical properties that can be expected within a variety of rock associations. Case studies, where geology has been a vital factor, are included. These are written by the project engineers or geologists responsible for the projects. Geology for Ground Engineering Projects is well illustrated with color diagrams and photographs. Readers are directed to satellite images of selected areas to explore for themselves many of the geological features described in this book.

Glacial soils are composite soils with significant variations in composition and properties and are recognised as challenging soils to deal with - and they do not always conform to classic theories of soil mechanics. This book for designers and contractors brings together many years of experience of research in both earth sciences and engineering into the behaviour of glacial deposits, drawing upon published and unpublished case studies from industry. It draws on recent developments in understanding of the geological processes and the impact they have upon the engineering properties, construction processes and performance of geotechnical structures.

The importance of glacial deposits is continually increasing, not only for pure scientists, but also for applied geologists. In many parts of Europe, as well as North America, these deposits provide major sand and gravel reserves, groundwater reservoirs and the foundation on which houses, roads and bridges are built. They are thus fundamental to many environmental and engineering problems. In this volume forty six authors report on the current state of specialist research on various aspects of glacial deposits. The geographical coverage of their work — Norway, Sweden, Denmark, West Germany and the Netherlands — represents a transect from the centres of the major North European Quaternary glaciations to their margins. Among the topics covered are: drift prospecting, modern varve chronology, fine gravel analysis, internal structure of thrust moraines, stratigraphical interpretation of well-logs, echo-sounding of North Sea deposits, erratic pebbles as indicators, till fabrics, palaeontology of glacial deposits, multi-component analyses, glacial deposition on the continental shelf and the genetic interpretation of glacial landforms. In addition there are reviews of the regional stratigraphy and glacial chronology of each of the five countries represented and detailed discussion of the problems of genesis, reworking, transport and deposition of Quaternary glacial sediments. Much information is previously unpublished. The volume is intended to serve both as a text book for students and informed amateurs and as a guide for professional geoscientists. The 53 chapters are richly illustrated (409 black and white illustrations and 95 colour photos). In addition to a full and detailed index, the book contains one of the most up-to-date and complete lists of the most important literature on Quaternary problems in North-West Europe, with over 700 references, which serve as a guide for further studies.

Sediments are the most valuable form of physical evidence for past Earth surface processes. They have the potential to build up an archive of events and provide a window into the past. Through careful examination of sediments the shifting patterns of surface processes across space and time are revealed, allowing us to reconstruct past environments and environmental change. A Practical Guide to the Study of Glacial Sediments is a guide to the standard techniques employed to read the sedimentary record of former glaciers and ice sheets. It demonstrates that the often complex and fragmentary glacial sedimentary record can, when examined systematically and rationally, provide detailed insights into former environments and climates in places where no other evidence is available. The complementary techniques covered in this book include: facies description, grain size analysis, clast form assessment, clast macrofabric analysis, micromorphology, particle lithology and assessment of engineering properties. They yield consistent and meaningful results in a range of glacial depositional environments throughout the world, from the high Arctic to the Himalayas. A Practical Guide to the Study of Glacial Sediments provides students and researchers with a clear and accessible guide to recording and interpreting glacial successions wherever the location.
