Based on the long-term engineering experiences of the author, field measurements together with back analyses are presented as the most powerful tools in rock engineering practice. This book is the first to describe an observational method in rock engineering practice, which implies that the potential readers of this book must be practicing engineers working on rock engineering projects."--PPN: PPN: 1003032095Package identifier: Produktsigel: ZDB-4-NLEBK
