Given the recent advances in site investigation techniques, computing, access to information and monitoring, plus the current emphasis on safety, accountability and sustainability, this book introduces an up-to-date methodology for the design of all types of rock engineering projects, whether surface or underground. Guidance is provided on the nature of the modeling to support design and the information required for design; also included is a procedure for technical auditing of the modeling and design together with the related protocol sheets. Written by two eminent authors, clearly structured and containing many illustrations, this volume is intended for consulting engineers, contractors, researchers, lecturers and students working on rock engineering projects.

Biography
Professor Xia-Ting Feng obtained his PhD in Civil Engineering at the Northeastern University, China, where he continued as a Professor. He was admitted by the Hundred Talents Program to the Chinese Academy of Sciences (CAS) in 1998 and later permanently joined CAS’s Institute of Rock and Soil Mechanics. He later obtained the support of the China National Funds for Distinguished Young Scientists and became a Chair Professor of the Cheung Kong Scholars’ Programme of the Chinese Ministry of Education. Dr Feng is the President of the International Society for Rock Mechanics for the period 2011–2015. He has made original contributions to the subject of ‘intelligent rock mechanics’ and his methods have been applied to large rock engineering projects in China and other countries.
Professor John A. Hudson graduated in 1965 from the Heriot-Watt University, UK, and obtained his PhD at the University of Minnesota, USA. He has spent his professional career in engineering rock mechanics—as it applies to civil, mining and environmental engineering—in consulting, research, teaching and publishing and was awarded the DSc. degree for his contributions to the subject. In addition to authoring many scientific papers and books, he edited the 1993 five-volume Comprehensive Rock Engineering compendium, and the International Journal of Rock Mechanics and Mining Sciences from 1983–2006. Since 1983, he has been affiliated with Imperial College, London as a Reader, Professor, and now Emeritus Professor and was elected as a Fellow of the UK Royal Academy of Engineering in 1998. Prof. Hudson was the President of the International Society for Rock Mechanics between 2007 and 2011. He is also an Honorary Professor at the University of Hong Kong and an Adjunct Professor in the Chinese Academy of Sciences.
This highly original and innovative book is the outcome of the work of the Commission on Rock Engineering Design Methodology of the International Society for Rock Mechanics (ISRM) in the period 2007–2011. The work of the Commission was managed by the authors, Professor John A Hudson, ISRM President for 2007–2011, and Professor Xiating Feng, ISRM President for 2011–2015, in association with the Chinese Society for Rock Mechanics and Engineering. Recently, this reviewer (2011) has argued that the work of its Commissions has been among the major achievements of the ISRM in the 50 years since its foundation in 1962. This book adds to that impressive record of achievement.
This superb book has many outstanding features. Its original approach and arguments are set out and developed with the greatest clarity; the writing is clear, fluent and accessible; the structure of the book is logical, guiding the reader through a series of stages required to develop a good, or even deep, understanding of the subject matter; the chapter summaries are succinct and informative, as are the summaries of some topics presented in tables and figures; and the detailed technical auditing approach developed is especially valuable. Perhaps most importantly, the several detailed practical examples given in each chapter illustrate just how the approaches developed and described have been applied in practice to the most challenging rock engineering design projects. These examples, together with a summary given in Chapter 1, provide compelling evidence of the monumental achievements of rock mechanics and rock engineering in China in recent years. Through this book and in other ways, the authors have contributed significantly to those achievements.
