Book Description
Shield Construction Techniques in Tunnelling presents the latest on this fast, environmentally-friendly and relatively safe construction technique, reflecting on its technical risks and challenges as seen in China. Sections introduce the type of shields, the history of the technique, shielding principles, selection, management, the latest techniques in operation, consider engineering cases, discuss construction in gravel, soft-soil, composite, and rock strata, and present video clips of construction that are accessible through QR codes embedded in the text. The book combines theory and practical experience, giving the reader unique insights into shield equipment and construction techniques. The shield tunneling technique is being used very widely, particularly in China, which is building urban-rail transit systems at an unparalleled scale and speed. The use of tunneling-shields provides a fast, relatively-safe, and ecologically-friendly method for the construction of tunnels. However, a number of incidents have shown the risks involved in tunnelling through geologically complex areas. Gives the principles and practice of shield construction techniques, including shield selection and operation Demonstrates the latest technologies in shield construction that can be applied in practice Reflects on the technical risks and challenges of shield construction, based on extensive use of the technique for tunnel construction in China Discusses challenges in construction in gravel, soft-soil, composite and rock strata Provides engineers with applicable insights into shield equipment and construction techniques

Book Description
Since its early beginnings in 1806, this type of tunnelling has become one of the most important techniques. While Japan's current pioneering role cannot be denied, the state of development in Europe has reached a high level of international recognition. This book explains the history of this construction method, outlining basic information and presenting the various types of shields and linings with the corresponding equipment and range of applications. It examines various projects, including not only such large ones as the Channel or the Belt tunnel, but also small, equally interesting projects such as underground railways. The problems involved as well the technology used to confront them are fully described, and the text is structured in such a way that readers are led from the basics of this construction method, via the essential functional elements of the shield machines and on to the different types of shields. The universality of the book is guaranteed by the three expert authors, a researcher, machine manufacturer and contractor respectively. Invaluable for current and future tunnelling projects and a must for all those working in the field.

Book Description
This book focuses on some technical problems encountered in shield tunneling in hard–soft uneven stratum and extremely soft stratum, based on the recent shield tunneling engineering practice, and summarizes the achievements of shield tunneling in view of the technical problems from an overall and objective perspective. There are 6 chapters in this book. Chapter 1 introduces the development trend of shield tunneling method, defines classification of various stratum where shield tunneling applies, and mainly analyses the selection of shield machines and the configuration of cutters. Chapters 2 to 5 elaborates the strata characteristics and construction difficulties under various stratum conditions, puts forward adaptive selection and design keys of shield in various stratum, and emphatically analyses and summarizes the stability control technologies of shield tunnel face and driving control technology by case studies. Chapter 6 introduces the shield chamber opening technologies under hyperbaric condition, emphatically presents the basic requirements and operational preparations for the shield chamber opening, and puts forward innovative ideas of operation procedures, control points of key procedures, and safety requirements of shield chamber opening under hyperbaric condition.

Book Description
This book examines how the state of underground structures can be determined with the assistance of force, deformation and energy. It then analyzes mechanized shield methods, the New Austrian tunneling method (NATM) and conventional methods from this new perspective. The book gathers a wealth of cases reflecting the experiences of practitioners and administrators alike. Based on statistical and engineering studies of these cases, as well as lab and field experiments, it develops a stability assessment approach incorporating a stable equilibrium, which enables engineers to keep the structure and surrounding rocks safe as long as the stable equilibrium and deformation compliance are maintained. The book illustrates the implementation of the method in various tunneling contexts, including soil-rock mixed strata, tunneling beneath operating roads, underwater tunnels, and tunnel pit excavation. It offers a valuable guide for researchers, designers and engineers, especially those who are seeking to understand the underlying principles of underground excavation.

Book Description
In the 21st century, the increasing scope of urban tunneling projects necessitates ever more complex construction methods to meet ecological, ecopolitical and economic demands. Tunnels are becoming longer, deeper and larger, making successful projects more difficult to realize. The special constraints of urban settings, including extremely stringent performance requirements for minimal disturbance to the public and to the surrounding utilities, structures and the environment, greatly exacerbate the challenges of successful tunnelling. Based on over twenty years' experience, Fundamentals of Shield Tunnelling--Design and Construction provides comprehensive and current guidance on key aspects of the design and construction of shield tunnels from the basic concepts to detailed technical requirements. It contains numerous case studies examining projects completed over the past decade, including the large diameter Shanghai Yangtze river tunnel and Qianjiang river tunnel, together with smaller diameter projects such as underground railways and maglev tunnels. Although shield tunnelling has been addressed in numerous articles, only a few books consider modern case histories in detail. This book, by internationally recognised experts is intended to fill this gap.
