Book Description
Mechanised shield tunnelling has developed considerably since the publication of the first edition of this book. Challenging tunnel projects under difficult conditions demand innovative solutions, which has led to constant further development and innovation in process technology, constructions operations and the machines and materials used. The book collects the latest state of technology in mechanised shield tunnelling. It describes the basics of mechanised tunnelling technology and the various types of machines and gives calculation methods and constructural advice. Further chapters cover excavation tools, muck handling, tunnel support, surveying and steering as well as workplace safety. There is also detailled information about contractual aspects and process controlling.

Book Description
Quantum tunnelling is one of the strangest phenomena in chemistry, where we see the wave nature of atoms acting in “impossible” ways. By letting molecules pass through the kinetic barrier instead of over it, this effect can lead to chemical reactions even close to the absolute zero, to atypical spectroscopic observations, to bizarre selectivity, or to colossal isotopic effects. Quantum mechanical tunnelling observations might be infrequent in chemistry, but it permeates through all its disciplines producing remarkable chemical outcomes. For that reason, the 21st century has seen a great increase in theoretical and experimental findings involving molecular tunnelling effects, as well as in novel techniques that permit their accurate predictions and analysis. Including experimental, computational and theoretical chapters, from the physical and organic to the biochemistry fields, from the applied to the academic arenas, this new book provides a broad and conceptual perspective on tunnelling reactions and how to study them. Quantum Tunnelling in Molecules is the obligatory stop for both the specialist and those new to this world.

Book Description
Tunnelling provides a robust solution to a variety of engineering challenges. It is a complex process, which requires a firm understanding of the ground conditions as well as the importance of ground-structure interaction. This book covers the full range of areas related to tunnel construction required to embark upon a career in tunnelling. It also includes a number of case studies related to real tunnel projects, to demonstrate how the theory applies in practice. New features of this second edition include: the introduction of a case study related to Crossrail’s project in London, focussing on the Whitechapel and Liverpool Street station tunnels and including considerations of building tunnels in a congested urban area; and further information on recent developments in tunnel boring machines, including further examples of all the different types of machine as well as multi-mode machines. The coverage includes: Both hard-rock and soft-ground conditions Site investigation, parameter selection, and design considerations Methods of improving the stability of the ground and lining techniques Descriptions of the various main tunnelling techniques Health and safety considerations Monitoring of tunnels during construction Description of the latest tunnel boring machines Case studies with real examples, including Crossrail’s project in London Clear, concise, and heavily illustrated, this is a vital text for final-year undergraduate and MSc students and an invaluable starting point for young professionals and novices in tunnelling.

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 text presents the results of the joint research initiative "Numercial Simulation in Tunneling". In doing so it provides a thorough guide to improving the safety and economy of tunnels by discussing the application of numerical simulation methods to assist tunnel engineers. Numerical simulation tools for the estimation of the required tunnel support and the required construction measures are described in this book. By using them, it is possible to study the impact on the construction and on the environment at the planning stadium and during construction. This will result in an improvement of the safety and economy of tunnels.

Book Description
Tunnelling has become a fragmented process, excessively influenced by lawyers'notions of confrontational contractual bases. This prevents the pooling of skills, essential to the achievement of the promoters' objectives. Tunnelling: Management by Design seeks the reversal of this trend. After a brief historical treatment of selected developments, th

Book Description
Der Ingenieurtunnelbau ist einer der ältesten, interessantesten, aber auch schwierigsten Ingenieurdisziplinen und erfordert theoretische Kenntnisse und praktische Erfahrung in Geologie, Geomechanik, Statik, Massivbau, Maschinentechnik, Bauverfahrenstechnik und Baumanagement. Das zweibändige "Handbuch des Tunnel- und Stollenbaus" gilt seit 30 Jahren in der deutschsprachigen Fachwelt als Standardwerk für Lehre und Praxis. Die vorliegende englische Ausgabe basiert auf einer überarbeiteten und angepassten Fassung der dritten deutschen Auflage und ist auf dem heutigen Stand der Kenntnisse. Das Buch erscheint in zwei Bänden, wobei sich der erste Band den mehr praktischen Themen von Konstruktion und Bauverfahren im Sprengvortrieb und maschinellen Vortrieb widmet. Der zweite Band widmet sich sowohl theoretischen Themen wie Planungsgrundsätze als auch praktischen Belangen der Baustellenabwicklung sowie Fragen der Ausschreibung, Vergabe und Vertrag.

Book Description
In recent years, there has been an explosion in knowledge and research associated with the field of enzyme catalysis and H-tunneling. Rich in its breath and depth, this introduction to modern theories and methods of study is suitable for experienced researchers those new to the subject. Edited by two leading experts, and bringing together the foremost practitioners in the field, this up-to-date account of a rapidly developing field sits at the interface between biology, chemistry and physics. It covers computational, kinetic and structural analysis of tunnelling and the synergy in combining these methods (with a major focus on H-tunneling reactions in enzyme systems). The book starts with a brief overview of proton and electron transfer history by Nobel Laureate, Rudolph A. Marcus. The reader is then guided through chapters covering almost every aspect of reactions in enzyme catalysis ranging from descriptions of the relevant quantum theory and quantum/classical theoretical methodology to the description of experimental results. The theoretical interpretation of these large systems includes both quantum mechanical and statistical mechanical computations, as well as simple more approximate models. Most of the chapters focus on enzymatic catalysis of hydride, proton and H" transfer, an example of the latter being proton coupled electron transfer. There is also a chapter on electron transfer in proteins. This is timely since the theoretical framework developed fifty years ago for treating electron transfers has now been adapted to H-transfers and electron transfers in proteins. Accessible in style, this book is suitable for a wide audience but will be particularly useful to advanced level undergraduates, postgraduates and early postdoctoral workers.
