Book Description
This completely revised and updated edition with all new color photos brings together in a single volume the anchoring systems most popular among climbers. Most climbers today learn their craft on artificial climbing walls and on sport routes with fixed protection. Their first efforts to lead on trad routes often come as a rude shock--they find that they haven't the skills and training to safeguard the climb or to set up solid belays. This new edition of Climbing Anchors is the climber's complete and authoritative source of information on protection, from fundamental knots to sophisticated rigging and equalizing skills.

Book Description
Advances in Rock-Support and Geotechnical Engineering brings together the latest research results regarding the theory of rock mechanics, its analytical methods and innovative technologies, and its applications in practical engineering. This book is divided into six sections, rock tests, rock bolting, grouted anchor, tunneling engineering, slope engineering, and mining engineering. Coverage includes fracture hinged arching process and instability characteristics of rock plates, failure modes of rock bolting, scale effects, and loading transfer mechanism of the grouted anchor. Also covered are recent innovations and applications in tunneling engineering, slope engineering, and mining engineering. This book provides innovative, practical, and rich content that can be used as a valuable reference for researchers undertaking tunneling engineering, slope engineering, mining engineering, and rock mechanics, and for onsite technical personnel and teachers and students studying the topics in related universities. - Enriches new theories on failure modes of rock plates, rock bolting mechanisms, and anchor loading transfer - Develops new methods of evaluating the stability of slope engineering and the roof stability of the mined-out areas - Includes fracture hinged arching process and instability characteristics of rock plates, failure modes of rock bolting, scale effects, and loading transfer mechanism of the grouted anchor

Book Description
Treating anchorages as a direct application of the laws of statics and the theories governing the transfer of load, this book focuses on designs that are safe and reasonably priced. It is divided into two parts. Following a general introduction in the first chapter, Part One goes on to explore anchor systems, components, installation and construction details. Presents special anchor systems such as extractable, compression-type, multibell, and regroutable anchors. Analyzes the transfer of load and its relation to failure modes and anchor load capacity; deals with design considerations; covers mechanisms and types of corrosion; and details anchor stressing, testing programs, and evaluation standards. Part Two considers uses and applications and design aspects of anchored structures; presents design examples of practical value and reasonable simplicity; and incorporates examples and case histories.

Book Description
This includes the Proceedings of the international symposium, Abisko, Sweden, 28 August-2 September 1983. Rock bolts today represent the dominant support system in mines and underground structures. Some results and experiences are discussed to give a better understanding of the strength of individual rock bolts and systems of bolts, and the interaction between bolts and rock masses of various types. Topics covered are as follows: rock bolting in theory and experiments; design principles and experience; and ground control and instrumentation: cable bolting.

Book Description
Rigging Modern Anchors, by Drew Frye, is possibly the most comprehensive guide ever written to demystify the subject of anchoring, especially about today's new anchors. The author, over years of systematic testing with a variety of different anchors and rigs, has produced a new benchmark for anchoring knowledge based on empirical data. Most anchoring mythology is based on anecdotal wisdom passed from one sailor to the next. Often what seems to work or doesn't work has no basis beyond the fact that it was handed down as the conventional wisdom. Finally, Frye has produced a book on anchoring that digs deeply into the how and why of anchoring. This book contains in-depth discussions of anchoring basics, loads, scope, cyclical loading and soil consolidation, discussions of bottom characteristics and holding power. There are anchor-specific observations, discussions of tandem anchors and rigging schemes, plus an extensive appendix containing data tables, test data, open source designs for bridle plate and anchor turner, Strength and toughness of different types of chain and rope, data tables on chain and line thickness, choosing connectors, extensive anchor size recommendations based on different manufacturers, and much more.Proper anchoring and anchor choice is critical to the safety of ship and crew. Instead of hoping that your anchor and rigging scheme will hold in a given situation, read Rigging Modern Anchors and be sure of it.

Book Description
Rockbolting: Principles and Applications brings current theoretical and practical developments in the most widely used support device for underground rock excavations. Today, one cannot find any rock excavation project that does not use rockbolts for rock support. The worldwide annual assumption of rockbolts is in the billions, with pieces applied to mines, tunnels and other types of geotechnical projects for rock and soil reinforcement. The text is based on over 25 years of experience of the author both as academic and practitioner. The book introduces the principles and background concepts of rock support, and then offers a comprehensive overview of the mechanics of rockbolting, as well as current rock bolt types such as mechanical, grouted, self-drilling, grouted cables, frictional and yield rockbolts. Installation and performance assessment are covered next including load-displacement curves and energy-absorption capacities. Two chapters on design and quality control, respectively, cover failure mechanics, the selection process and the connections with other supporting devices. On quality control, the author explains the usual tests and displacement measurements. The final chapter brings current case studies that combine the concepts presented in the whole book. The book is a professional reference for engineers in the mining and geotechnical industries and can be used as research material for academics in rock mechanics and stability studies. - Offers theoretical knowledge on rock bolts and rockbolting - Covers the standard and most recent types of rockbolts - Includes information on rockbolting in high stress rock - Presents case studies that introduce practical applications in several conditions
