The views expressed in this book are the author’s own but he ~5ubh 2{
acknowledges his debt to his many immediate colleagues in Halcrow and to \e|U9;Mf
so many tunnellers and others around the world for several of the thoughts Mb/L~gd "
which have prompted the book. The author accepts full responsibility for Z:|9N/>T
any misunderstanding. The account may be criticised as unduly orientated 0Z,{s158L
towards the British and European examples. This is justified by selecting a1 |c2kT
examples for which the circumstances are generally familiar; lessons learned g ?V&mu
may well have more universal application. The Channel Tunnel, for * 0~M
example, provides many examples of meritorious engineering with less s@s/ '^`
meritorious management. An exemplary account of its engineering geology |Y tg
(Harris et al. 1996) attracts numerous references on account of its depth and H*rx{ F?
breadth.
