This three-volume set provides a global, up-to-date, thorough, clear, and practical new risk-based approach to tunnelling design and construction methods and discusses detailed examples of solutions applied to relevant case histories. The set covers all aspects of tunnelling, providing useful and practical information about design, construction, and best practices. It is organised 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

It provides the following features and benefits:

1) updated vision on tunnelling design, tools, materials, and construction

2) balanced mix of theory, technology and applied experience

3) different and harmonized points of view from academics, professionals, and contractors

4) easy consultation in form of a handbook

5) risk-oriented approach to tunnelling problems

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