The views expressed in this book are the author’s own but he F{}:e QD
acknowledges his debt to his many immediate colleagues in Halcrow and to 7FP"]\x
so many tunnellers and others around the world for several of the thoughts ~H]d9C
which have prompted the book. The author accepts full responsibility for mj9]M?]
any misunderstanding. The account may be criticised as unduly orientated x}reeqn
towards the British and European examples. This is justified by selecting Vr&v:8:wb
examples for which the circumstances are generally familiar; lessons learned ZQ[ s:
may well have more universal application. The Channel Tunnel, for 91#n A j%
example, provides many examples of meritorious engineering with less -r0oO~KT
meritorious management. An exemplary account of its engineering geology `WQpGBS_z_
(Harris et al. 1996) attracts numerous references on account of its depth and P|aSbsk:I<
breadth.
