The theory of tunnel design has lagged behind the development of design techniques, which are based on experience in the field. For example, tunnels are normally lined with concrete after excavation, but there is no reliable basis in theory for determining the thickness of the lining to be used. As a result, some linings are too thick, while others are so thin that tunnels collapse. After tunnelling, if the strain energy, which accumulates in the ground as a result of diastrophism and the influence of gravity, exceeds a certain limit, the ground around a tunnel will collapse.
The purpose of this book is to develop theoretical design principles based on the authors' studies of strain energy. A knowledge of tunnel mechanics based on strain energy will give engineers a new theoretical basis for tunnel design and construction.

Develops theoretical principles for designing tunnels based on studies of strain energy, for engineers to use in conjunction with the design techniques that have been thoroughly learned over the years by practical experience. For example, once tunnels are dug, they are usually lined with concrete, but there is no theoretical basis for calculating the thickness of the concrete, only guesswork based on previous failures. Offers methods for the stability analysis of all the major types of tunnels. Distributed in the US by Columbia U. Press. Annotation copyright Book News, Inc. Portland, Or.
