This is a text for undergraduate and MSc students, or a reference for professionals, covering all aspects of tunnel construction with case studies related to real projects. With reference to both soft ground and hard rock tunnelling, the book covers the main techniques along with site investigation, parameter selection, and design considerations. "The authors have packaged the information with a very wide range of tables, figures, key equations and source references. Many readers will find all they ever wanted to know about tunnel construction without leaving its pages; while those for whom it whets the appetite to dig deeper (pun intended!) will find comprehensive pointers to up-to-date sources of literature elsewhere." -- Andrew Dawson, Nottingham University, UK
