Majosta Practical Guide to Rock Tunneling: 2nd Edition

This Practical Guide to Rock Tunneling fills an important gap in the literature for a practical guide to the design and construction of rock tunnels. The Practical Guide to Rock Tunneling takes the reader through all the key stages of rock tunnel design and construction starting with geotechnical ground investigations to construction supervision. The guide provides suggestions and recommendations for professionals on particular topics such as laboratory testing, rock durability and acceptability of unlined water tunnels, overstressing including rockbursting in long and deep tunnels, evaluation of risk-based excavation methods, contractual strategies, and post-construction inspections. Key additional information is included in this 2nd Edition including the following: •Updated in situ stress graphic based on deep testing data •TBM Risk Assessment and Selection for hydroelectric tunnels; •TBM Tunnel Support – new Q/RMR chart for TBMs based on case projects; •Deterioration/slaking impacts to TBM excavation and mucking operations; •Hydroelectric tunnel layout design; •Seismic design considerations for tunnels in rock; •Industry recommendations for the inspection of aging hydroelectric tunnels; •Raisebore stability evaluation; •Tunnel lining requirements for geological faults in hydroelectric tunnels; •Use of drones for inspection of historical tunnels, and; •Additional international case histories and lessons learned. Instead of reviewing all the theory and concepts that can be found in other sources, this book contains the hard lessons learned from the author's experience in the field of rock tunneling, gathered in more than 35 years and 1500km of tunnels for civil, hydroelectric and mining infrastructure projects including some of the most recognized projects in the world to date.
