Immersed tunnels have been around for more
than a century but remain a relatively unknown form of tunnel
construction. For waterway crossings they are an effective alternative
to bored tunnels and bridges, particularly in shallower waters, soft
alluvial soils, and earthquake-prone areas. Successful implementation
requires a thorough understanding of a wide variety of civil engineering
disciplines and construction techniques. Immersed Tunnels brings
together in one volume all aspects of immersed tunnels from initial
feasibility and planning, through design and construction, to operation
and maintenance. The
book presents design and construction principles to give a full
appreciation not only of what is involved in an immersed tunnel scheme
but also how potential problems are dealt with and overcome. It examines
important factors that have to be considered, particularly
environmental implications and mechanical and electrical systems. It
also gives practical examples of how specific techniques have been used
in various projects and highlights issues that designers and
constructors should be aware of. In addition, the book discusses
operation and maintenance and reviews contractual matters. These aspects
are described from the viewpoint of two experienced practitioners in
the field who have a wealth of experience on immersed tunnel projects
worldwide. As tunnels are increasingly being adopted as
engineering solutions around the world, this unique and extensively
illustrated reference explores the wide variety of immersed tunnel
techniques available to designers and constructors. It provides
essential insight for anyone involved, or seeking to be involved, with
immersed tunnel projects.
