This book covers all aspects of immersed tunnel schemes from initial feasibility and planning through to design, construction, and operation and maintenance. It considers environmental implications and gives practical examples given of how the issues have successfully been addressed on various schemes. It also provides an analysis of design and construction principles to give you a fuller appreciation not only of what is involved in an immersed tunnel scheme but also how potential issues are dealt with and overcome. These aspects are described from the viewpoint of two experienced practitioners in the field who have a wealth of experience. This unique reference addresses the numerous issues which need to be considered on an immersed tunnel project and shows you how these have been overcome in real practice. As tunnels are increasingly adopted as engineering solutions around the world, this book provides essential insight for engineers involved, or seeking to be involved, in immersed tunnel projects.目录Foreword 1.
