Название: Tunelling [sic] and tunnel mechanics. A rational approach to tunnelling
Автор: Kolymbas D.
So while this book is designed to provide a concise, up-to-date and useful frame of reference to all those newly qualified and engaged in the field, I hope that it will also serve to reveal to those talented engineers who thought they had found their niche above ground the very real opportunities and unanswered questions that await them underground.
