U.S. Department of Transportation, 1989. – 548 p.
This manual has been prepared by Golder Associates, Seattle, Washington, in conjunction with a series of Rock Slope Engineering courses sponsored by the Federal Highway Administration.
The manual is based on a book entitled Rock Slope Engineering authored by Dr. Evert Hoek and Dr. John Bray. A third edition of this book has been published in 1981. The book has been modified for these courses by expanding the chapter on Blasting and preparing new chapters on Slope Stabilization, Movement Monitoring and Construction Contracts and Specifications. A glossary of excavation terms, listings and documentation of two slope stability programs and a data collection manual have been added as appendices. The entire text has been edited to make it applicable to transportation engineering.
This manual is concerned with the stability of rock slopes, with methods for assessing this stability and with techniques for improving the stability of slopes which are potentially hazardous. It is intended that it serve as both an Instruction manual for engineers carrying out slope stability investigations and designing rock slopes, and a guide for construction engineers involved with excavation and stabilization. With this purpose in mind, the manual contains sections on methods of rock slope design, practical exercises demonstrating the application of these methods, sections on blasting, slope stabilization, contracts and contract management.
