During the 1980's, research was being carried out to instrument and monitor the piled foundation beneath one leg of the BP Magnus platform in order to determine the actual loads imposed on the piles and seabed by the structural and environmental forces. This volume brings together the findings and discussions resulting from this research.

This book brings together all the Symposium papers from leading international researchers, published in Geotechnique, the keynote speeches presented at the Symposium, at the Institution of Civil Engineers on 20 June 2011, and a selection of questions posed by delegates during the Symposium, together with answers from presenters.

Safe Intrusive Activities on Land Potentially Impacted by Contamination provides health, safety and environmental information and good practice recommendations for professionals engaged with intrusive activities on land potentially impacted by contamination. The book is relevant to all intrusive activities, including ground investigations, piling, land drilling, earthworks and ground remediation. This publication aims to promote safe working practices, and to improve awareness of health, safety and environmental matters. Land potentially affected by contamination contains particular hazards that require the employment of specialist geoenvironmental services with appropriately trained and experienced office and site personnel, suitable plant and equipment, and high levels of supervision and response. The guidance has been structured to be read as a whole in the order presented. Coverage reflects recent developments in health, safety and environmental legislation, and changes to working practices, equipment and methods, and also the greater prominence given continuous risk assessment.Safe Intrusive Activities on Land Potentially Impacted by Contamination is relevant to all professionals working in this area, including individuals and organisations involved in specification, procurement, execution or supervision."

This book summarizes new discoveries on fracturing in chalk. Based on studies on the Danish North Sea, this book shows how observations from outcrop analogues, core and seismic data can be used to characterize the density, distribution and geometry of natural fractures in chalk and marl. Laboratory experiments on chalk samples reveal the controls on the geomechanical properties of chalk and thus on the growth of natural fractures. Finally, various modeling techniques are employed to investigate the mechanical deformation in the chalk structures of the Danish North Sea and to predict fracture distribution and geometry in the subsurface. An understanding of fracture density, distribution and geometry is essential for planning efficient fluid extraction or injection strategies and CO2 sequestration. This book provides the necessary knowledge.

The subject of thermo-hydro-mechanical coupled processes in fractured rock masses has close relevance to energy-related deep earth engineering activities, such as enhanced geothermal systems, geological disposal of radioactive waste, sequestration of CO2, long-term disposal of waste water and recovery of hydrocarbons from unconventional reservoirs. Despite great efforts by engineers and researchers, comprehensive understanding of the thermo-hydro-mechanical coupled processes in fractured rock mass remains a great challenge. The discrete element method (DEM), originally developed by Dr. Peter Cundall, has become widely used for the modeling of a rock mass, including its deformation, damage, fracturing and stability. DEM modeling of the coupled thermo-hydro-mechanical processes in fractured rock masses can provide some unique insights, to say the least, for better understanding of those complex issues.The authors of this book have participated in various projects involving DEM modeling of coupled thermo-hydro-mechanical processes during treatment of a rock mass by fluid injection and/or extraction and have provided consulting services to some of the largest oil-and-gas companies in the world. The breadth and depth of our engineering expertise are reflected by its successful applications in the major unconventional plays in the world, including Permian, Marcellus, Bakken, Eagle Ford, Horn River, Chicontepec, Sichuan, Ordos and many more. The unique combination of the state-of-the-art numerical modeling techniques with state-of-the-practice engineering applications makes the presented material relevant and valuable for engineering practice. We believe that it is beneficial to share the advances on this subject and promote some further development.

This volume highlights the latest advances and innovations in the field of soil mechanics and geotechnical engineering, as presented by leading international researchers and engineers at the 5th International Conference on New Developments in Soil Mechanics and Geotechnical Engineering (ZM), held in Nicosia, Northern Cyprus on June 30-July 2, 2022. It covers a diverse range of topics such as soil properties and characterization; shallow and deep foundations; soil improvement; excavations, support systems, earth-retaining structures and underground systems; earthquake geotechnical engineering; stability of slopes and landslides; fills and embankments; environmental preservation, water and energy; modelling and analyses in geotechnical engineering. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster multidisciplinary collaboration among different specialists.

Mining is essential for extracting natural resources. However, it is costly, potentially dangerous if poorly managed, and is perceived by some to be an environmentally unfriendly process. This book provides a comprehensive overview of mining technology with case examples and research. Chapters discuss a diversity of topics, including sonic drilling, quality assessment of rock bolts, block cave mine ventilation, microwave radar surveillance, safety management of tailings, and monitoring radon gas in underground mines.

This book provides a timely review on recent advancements in rock-filled concrete dam: a new type of dam originated from Tsinghua University in China. It covers historical overview of the development, filling process of high performance self-compacting concrete, mechanical and physical properties of rock-filled concrete, design of rock-filled concrete gravity dams and arch dams, as well as construction and quality control specifications. The book is intended for researchers, practicing engineers and graduate students who are interested in fundamental research and engineering design principles of rock-filled concrete dams. Successful insights gained from more than 120 rock-filled concrete dams completed or under construction in China are presented in this book, which can be useful references for all readers.
