The book provides a new, global, updated, thorough, clear and practical risk-based approach to tunnelling design and construction methods, and discusses detailed examples of solutions applied to relevant case histories. It is organized in three sequential and integrated volumes:

• Volume 1: Concept – Basic Principles of Design
• Volume 2: Construction – Methods, Equipment, Tools and Materials
• Volume 3: Case Histories and Best Practices

The book covers all aspects of tunnelling, giving useful and practical information about design (Volume 1), construction (Volume 2) and best practices (Volume 3). It provides the following features and benefits:

• updated vision on tunnelling design, tools, materials and construction
• balanced mix of theory, technology and applied experience
• different and harmonized points of view from academics, professionals and contractors
• easy consultation in the form of a handbook
• risk-oriented approach to tunnelling problems.

The tunnelling industry is amazingly widespread and increasingly important all over the world, particularly in developing countries. The possible audience of the book are engineers, geologists, designers, constructors, providers, contractors, public and private customers, and, in general, technicians involved in the tunnelling and underground works industry. It is also a suitable source of information for industry professionals, senior undergraduate and graduate students, researchers and academics.
