Description

The stability of underground and surface geotechnical structures during and after excavation is of great concern as any kind of instability may result in damage to the environment as well as time-consuming high cost repair work. The forms of instability, their mechanisms and the conditions associated with them must be understood so that correct stabilisation of the structure through rock reinforcement and/or rock support can be undertaken.

Rock Reinforcement and Rock Support elucidates the reinforcement functions of rock bolts/rock anchors and support systems consisting of shotcrete, steel ribs and concrete liners and evaluates their reinforcement and supporting effects both qualitatively and quantitatively. It draws on the research activities and practices carried out by the author for more than three decades and has culminated in a most extensive up-to-date and a complete treatise on rock reinforcement and rock support.

Reviews

"This book offers a wide variety of scholarly and applied approaches that can be used for stabilizing excavations in rock masses underground and surface. The author connects the theory with practice through numerous examples involving numerical modeling, laboratory testing, and in situ experimentations. These examples are mostly based on the author's wide-ranging experience worldwide on the subject. Rich in photographs and illustrations, the book offers educational and practical outcomes that can be used by the educators. The book gives an extensive coverage of the mechanisms involved during the rock mass - support interaction process, which are demonstrated through a wide variety of case histories. Also incorporated in the book are the examples from the rock reinforcement practices presented through detailed sketches and photographs. Researchers and practitioners can benefit from the book too as a valuable supplement to their work through a wide variety of numerical and in situ modeling exercises."
