Download The Second Half Century of Rock Mechanics
“The Second Half Century of Rock Mechanics” is a three-volume set that presents the proceedings from the 11th Congress of the International Society for Rock Mechanics (ISRM), which was held in Lisbon, Portugal, in July 2007. Edited by Claudio Olalla, Luís Ribeiro E. Sousa, and N. Grossmann, the book captures the state of rock mechanics over the past fifty years, offering a collection of research papers, case studies, and discussions on current and future challenges in the field.
The congress was organized by the Portuguese Geotechnical Society (SPG), in collaboration with the ISRM’s Portuguese National Group, and co-sponsored by the Spanish Society for Rock Mechanics (SMR). The event featured satellite workshops in Madrid and the Azores, short courses, and technical tours, providing a rich context for understanding the development and application of rock mechanics.
Evolution of Rock Mechanics Over the Past Fifty Years
Rock mechanics, a branch of geotechnical engineering, has evolved significantly since the first ISRM congress in 1966. The book reflects on the progress made in understanding rock behavior, modeling, and simulation techniques, and the development of new tools and methodologies. The field has grown to encompass various applications, such as tunneling, mining, earthquake engineering, petroleum engineering, and hydrocarbon storage.
Over the last fifty years, there has been a notable shift from purely theoretical studies to practical applications, driven by technological advancements and the increasing complexity of engineering projects. The congress highlighted these developments, bringing together experts from around the world to discuss innovations in rock mechanics and their applications to current and future engineering challenges.
Key Themes of the Congress
The congress and the resulting book covered several critical themes:
- Rock Engineering and Environmental Issues: This section focused on the relationship between rock mechanics and environmental sustainability. Topics included the impact of engineering activities on the natural environment, strategies for minimizing ecological footprints, and methods for preserving natural rock formations and landscapes.
- Characterization to Modeling: Advances in rock characterization methods, including geophysical techniques, laboratory testing, and in-situ testing, have significantly improved the ability to model rock behavior accurately. This section examined how these methods contribute to better predictions of rock behavior under various conditions, leading to safer and more efficient engineering designs.
- Slopes, Foundations, and Open Pit Mining: This theme addressed the challenges associated with slope stability, foundation design, and the development of open-pit mines. It included case studies on the application of rock mechanics principles to real-world problems, such as landslide mitigation, foundation stabilization, and the optimization of mining operations.
- Tunnels, Caverns, and Underground Mining: Tunneling and underground mining are critical areas of application for rock mechanics. This section provided insights into the latest research and techniques used in designing and constructing tunnels, caverns, and underground mines. Topics included rock support systems, excavation methods, and monitoring technologies to ensure safety and stability.
- Earthquake Engineering and Rock Dynamics: Understanding rock dynamics is essential for earthquake engineering. The book explored how rock mechanics principles are applied to design structures that can withstand seismic events, focusing on the behavior of rocks under dynamic loads, wave propagation through rock masses, and the development of models to predict seismic response.
- Petroleum Engineering and Hydrocarbon Storage: The extraction and storage of hydrocarbons require a deep understanding of rock mechanics. This section examined the role of rock mechanics in designing oil and gas wells, managing reservoirs, and ensuring the integrity of underground storage facilities. The discussion also covered new techniques for hydraulic fracturing, wellbore stability, and enhanced oil recovery.
- Safety Evaluation and Risk Management: Safety and risk management are paramount in all engineering projects. The book discussed methodologies for assessing and mitigating risks associated with rock engineering projects, including probabilistic approaches, risk-based design, and the integration of safety management systems into project planning and execution.
Workshops and Technical Tours
The congress featured several workshops and technical tours designed to provide practical insights into rock mechanics applications:
- Madrid Workshops: The two satellite workshops in Madrid focused on “Underground Works under Special Conditions” and “Preservation of Natural Stone and Rock Weathering.” These workshops addressed the unique challenges of underground construction in challenging environments, such as high-temperature zones, and the preservation of cultural heritage sites composed of natural stone.
- Azores Workshop: The “2nd International Workshop on Volcanic Rocks” in the Azores provided a platform to discuss the specific challenges and opportunities presented by volcanic rocks. Topics included the mechanical properties of volcanic rocks, their use in construction, and methods for mitigating the risks associated with volcanic activity.
- Technical Tours: The congress included several one-day technical tours in Portugal, which showcased innovative rock engineering projects, such as tunneling projects, dam constructions, and mining operations. These tours provided participants with a first-hand view of how theoretical knowledge is applied in practical settings.
