About the Book
The first thing you will need to do to appreciate the sheer scale of the information contained in this book, is to look at the Table of Contents below. Then ask yourself where else could you find all of this information in a single, modern book, with fully worked examples, and with a practical guide to actual remedial equipment and materials used. Yet, despite the complexity of the topics covered, the author has concentrated on using the simplest analyses, and always uses worked examples, so that the design engineer can be confident he/she has the proper units and has completed his/her calculations correctly.
The wide ranging nature of this book means that if you could have only one book on the subject, then this would have to be it. It will be your go-to reference book and mentor.
If you want to be able to say that you know rock face and rock slope stability, then all you have to do is read this book from beginning to end and then put it on your bookshelf where you can find it easily. That's all.
The objective of this book is to be comprehensive and thorough, starting with the geological knowledge necessary to understand the modes of discontinuity failure in different rock types. This is covered in Chapters 1 - 8. The book is comprehensive in that it does not leave out any aspect of the field work that an engineer will need to solve field problems. It deals with the recognition of different rock types, their outcrop patterns, and their jointing patterns. This part of the book is not just a general geology section; it is specifically tailored to the subject of rock slope stability, so that all of the information it contains is pertinent and relevant to the subject. The words constantly explain which geological features cause which slope stability problems, and why.
Following this is the key chapter of the book - Chapter 9, which goes through the mathematics of rock face and rock slope instability in the majority of forms that the user will come across as a working highway engineer or geotechnical engineer.
The fundamental principle of this book is to isolate and quantify the small modular units that either comprise individual potential failures in their own right, or else can form a component of a larger failure scenario. By teaching the modular units, the mathematics is simplified, and the user can decide which elements he or she desires to use in order to solve any potential problem. The comprehensive nature of the material covered is exemplified by the inclusion of all the necessary dynamic physics of moving rocks and rock masses, not just static analysis, as well as the potential effects on rock slopes caused by earthquakes or other ground-transported vibrations.
The book does not cover major slip circle type failures through rock masses (as opposed to failures along discontinuities) for two reasons. Firstly, because such failures come into the realm of soil failures and the techniques for analysing these are the same. Secondly, because analysing major failures in large mining pits and huge rock excavations is a specialist field that will not be (or should not be) tackled by the non-specialist for whom this book is intended.
Chapters 10 - 14 cover the design of retaining, or stabilisation structures for many different potentially unstable conditions ranging from individual falling rocks to mass sliding.
The book closes with four interesting Appendices. Whenever you are working in this field, then Appendix 1 contains the equations that you will need. Appendices 2 to 4 will be interesting to the reader and some may find them useful.
