Tunnels have a high degree of risk that needs to be assessed and managed. Underground works intersect and interact with natural materials, incorporating their characteristics as structural components of their own stability. For this reason geotechnical risk analyses are implemented at all phases of tunnel construction, from design through to post-construction maintenance. Analysis of geotechnical risk involves a group of studies which lead to the identification and evaluation of the potential probability of error and the consequences of its occurrence. This volume considers construction and safety, financing and control, and exploration and maintenance. Eminent specialists discuss risk assessment and management, based both on advanced theoretical concepts and on practical experience. The book is of interest to a wide range of professionals involved in planning, construction and management of tunnels: entrepreneurs, designers, consultants and contractors.

Forty one years ago, the International Society for Rock Mechanics (ISRM) held its 1st International Congress in Lisbon, Portugal. In July 2007, the 11th ISRM Congress returned to Lisbon, where the Portuguese Geotechnical Society (SPG), the Portuguese National Group of the ISRM, hosted the meeting. The Second Half Century of Rock Mechanics comprises the proceedings of the 11th ISRM Congress, and reviews how the discipline of Rock Mechanics has evolved over the past half century to become an important area of Geotechnical Engineering, and considers new perspectives and developments as well. The organization of the congress was co-sponsored by the Spanish Society for Rock Mechanics (SMR), who also organized two satellite workshops in Madrid ("Underground Works under Special Conditions" and "Preservation of Natural Stone and Rock Weathering"). The Congress also included another satellite workshop in the Azores ("2nd International Workshop on Volcanic Rocks"), several short courses, a selection of one-day technical tours in Portugal and other events. The Second Half Century of Rock Mechanics contains the complete papers presented by the ISRM National Groups, as well as transcripts of special lectures by invited speakers on key issues and recent research developments. The themes of general interest included: Rock Engineering and Environmental Issues; The Path from Characterization to Modelling; Slopes, Foundations and Open Pit Mining; Tunnel, Caverns and Underground Mining; Earthquake Engineering and Rock Dynamics; Petroleum Engineering and Hydrocarbon Storage; and Safety Evaluation and Risk Management. The Second Half Century of Rock Mechanics will be of interest to professionals, engineers, and academics involved in rock mechanics, rock engineering, tunnelling, mining, earth quake engineering, rock dynamics and geotechnical engineering.

Since the 1990s five books on ‘Applications of Computational Mechanics in Geotechnical Engineering’ have been published. Innovative Numerical Modelling in Geomechanics is the 6th and final book in this series, and contains papers written by leading experts on computational mechanics. The book treats highly relevant topics in the field of geotechnics, such as environmental geotechnics, open and underground excavations, foundations, embankments and rockfill dams, computational systems and oil geomechanics. Special attention is paid to risk in geotechnical engineering, and to recent developments in applying Bayesian networks and Data Mining techniques.Innovative Numerical Modelling in Geomechanics will be of interest to civil, mining and environmental engineers, as well as to engineering geologists. The book will also be useful for academics and researchers involved in geotechnics.

Underground geological storage of carbon dioxide (CO2) has considerable potential for mitigating climate change. CO2 can be safely injected and stored at well characterized and properly managed sites. Injecting carbon dioxide in deep geological formations can store it underground for long periods of time. Depleted oil and gas reservoirs, saline aquifers and carboniferous formations can be used for storage of CO2, as well as in abandoned coal mines. At depths below about 800-1000m, CO2 has a liquid-like density that permits the efficient use of underground reservoirs in porous sedimentary rocks.The papers in the present volume are from leading experts in the field of CO2 storage and were presented at an International Workshop on CO2 Storage in Carboniferous Formations and Abandoned Coal Mines (Beijing, China, 8-9 January 2011). CO2 storage in abandoned coal mines appears to have a bright future. Although CO2 Storage in Carboniferous Formations and Abandoned Coal Mines is primarily intended for mining engineers, environmental engineers and engineering geologists, the book will also be useful to civil engineers, and academics and professionals in geophysics and geochemistry.

This book offers a practical reference guide to soft rock mechanics for engineers and scientists. Written by recognized experts, it will benefit professionals, contractors, academics, researchers and students working on rock engineering projects in the fields of civil engineering, mining and construction engineering. Soft Rock Mechanics and Engineering covers a specific subject of great relevance in Rock Mechanics – and one that is directly connected to the design of geotechnical structures under difficult ground conditions. The book addresses practical issues related to the geomechanical properties of these types of rock masses and their characterization, while also discussing advances regarding in situ investigation, safety, and monitoring of geotechnical structures in soft rocks. Lastly, it presents important case histories involving tunnelling, dam foundations, coal and open pit mines and landslides.
