This book introduces shield construction risks under mixed face ground condition, analyzes the shield tunneling risks, gives definitions of relevant risks and creates the theoretical system of shield tunneling technology under mixed face ground condition, that is, geology is the foundation, TBM is the key, and people (management) is the essence. The content provides numbers of targeted solutions, such as dual-mode TBM, multi-mode TBM, millisecond delay blasting for boulders, Paste HDN, auxiliary pressure balance tunneling and so on. This book can make researchers who engaged in shield tunneling to get experiences and lessons from it, so as to make the right decision during shield type selection, standardize shield tunneling, take proper action, avoid or reduce construction risks, and minimize casualties and property losses.

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.

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

Expanding Underground - Knowledge and Passion to Make a Positive Impact on the World contains the contributions presented at the ITA-AITES World Tunnel Congress 2023 (Athens, Greece, 12 – 18 May, 2023). Tunnels and underground space are a predominant engineering practice that can provide sustainable, cost-efficient and environmentally friendly solutions to the ever-growing needs of modern societies. This underground expansion in more diverse and challenging infrastructure types or to novel underground uses can foster the changes needed. At the same time, the tunneling and underground space community needs to be better prepared and equipped with knowledge, tools and experience, to deal with the prevailing conditions, to successfully challenge and overcome adversities on this path. The papers in this book aim at contributing to the analysis of challenging conditions, the presentation and dissemination good practices, the introduction of new concepts, new tools and innovative elements that can help engineers and all stakeholders to reach their end goals. Expanding Underground - Knowledge and Passion to Make a Positive Impact on the World covers a wide range of aspects and topics related to the whole chain of the construction and operation of underground structures: Knowledge and Passion to Expand Underground for Sustainability and Resilience Geological, Geotechnical Site Investigation and Ground Characterization Planning and Designing of Tunnels and Underground Structures Mechanised Tunnelling and Microtunnelling Conventional Tunnelling, Drill-and-Blast Applications Tunnelling in Challenging Conditions - Case Histories and Lessons Learned Innovation, Robotics and Automation BIM, Big Data and Machine Learning Applications in Tunnelling Safety, Risk and Operation of Underground Infrastructure, and Contractual Practices, Insurance and Project Management The book is a must-have reference for all professionals and stakeholders involved in tunneling and underground space development projects.
