This is arguably the most comprehensive book currently available in the subject field. Yet it was not created for the expert rock mechanics engineer but for any graduate engineer working in the fields of highway construction, geology, geotechnical engineering, civil engineering, mining, quarrying, or rock mechanics. The following is an unsolicited testimonial sent to us by the Principal Geotechnical Engineer employed in one of the U.K.’s leading geotechnical consultancy companies shortly after he had obtained a copy. The wording has not been altered. “The book is very comprehensive and logically set out. From the theory of the formation of the solar system and the earth, through the different rock types and their weathering characteristics to the anatomy of different rock slopes and their instability, the book leaves the reader very aware of the complexities of the issues around rock slope engineering. What is particularly impressive is that the book provides the reader with the practical means to survey and understand rock slope failure mechanisms and provides the tools for their effective remediation. Clear examples are provided at each step. All in all, engineers with experience of this type of work will appreciate having this book at their fingertips and it is essential reading for anyone wanting to fully understand the elements of rock slope engineering. I wish I had access to this book at the beginning of my career and urge anyone serious in rock slope engineering to have a copy in their library. I had no difficulty in downloading the book. we have already used it to aid in a couple of recent schemes, and we have urged my team to make sure that they purchase a copy for themselves.”
