Tunnels are among the most demanding structures engineers create, carrying roads, railways, and utilities beneath mountains, cities, and bodies of water.Tunnels are among the most demanding structures engineers create, carrying roads, railways, and utilities beneath mountains, cities, and bodies of water. This book explains how such passages are planned, designed, and built. You will learn about the geological surveys that precede construction, the methods used to bore or excavate through rock and soil, and the techniques applied to keep tunnels safe and stable once in use. The book covers approaches ranging from traditional drilling and blasting to modern tunnel boring machines, as well as the particular challenges of working under rivers, seas, and densely populated urban areas. Written as a clear introduction to the subject, it offers you a factual overview of tunnel engineering without assuming prior technical knowledge.
