During the last two decades rock mechanics in Europe has been undergoing some major transformation. The reduction of mining activities in Europe affects heavily on rock mechanics teaching and research at universities and institutes. At the same time, new emerging activities, notably, underground infrastructure construction, geothermal energy development, radioactive waste and CO2 repository, and natural hazard management, are creating new opportunities of research and engineering. Rock mechanics today is closely associated with, and indeed part of, construction, energy, and environmental engineering. Rock Mechanics in Civil and Environmental Engineering collects 200 papers presented at the European Rock Mechanics Symposium EUROCK 2010, covering recent developments in rock mechanics. Topics include: rock mechanics theory, rock dynamics and rate dependent behaviour, laboratory and field test techniques, numerical modelling methods, and rock mechanics applications to engineering design, tunnel excavation and support, slope stabilisation, radioactive waste repository, petroleum and hydropower energy, earthquake and natural hazard management. The book will be invaluable to academics and engineers involved and interested in rock mechanics and rock.

The study of rock dynamics is important because many rock mechanics and rock engineering problems involve dynamic loading ranging from earthquakes to vibrations and explosions. The subject deals with the distribution and propagation of loads, dynamic responses, and processes of rocks and rate-dependent properties, coupled with the physical environment. Rock dynamics has a wide range of applications in civil, mining, geological and environmental engineering. However, due to the additional "4th" dimension of time, rock dynamics remains, in the discipline of rock mechanics, a relatively more challenging topic to understand and to apply, where documented research and knowledge are limited.Advances in Rock Dynamics and Applications provides a summary of the current knowledge of rock dynamics with 18 chapters contributed by individual authors from both academia and engineering fields. The topics of this book are wide-ranging and representative, covering fundamental theories of fracture dynamics and wave propagation, rock dynamic properties and testing methods, numerical modelling of rock dynamic failure, engineering applications in earthquakes, explosion loading and tunnel response, as well as dynamic rock support.

Rocks and soils can behave as discontinuous materials, both physically and mechanically, and for such discontinuous nature and behaviour there remain challenges in numerical modelling methods and techniques. Some of the main discontinuum based numerical methods, for example the distinct element method (DEM) and the discontinuous deformation analysis (DDA), are associated with geomechanics and geoengineering. Discontinuous numerical methods have been widely applied in geoengineering related to civil, mining, hydropower and petroleum engineering. There are many good examples of the use of UDEC/3DEC and DDA in design and forensic of geoengineering projects, in dams, slopes, tunnels, caverns and mines. The discontinuous numerical methods provide good tools to capture the true physical and mechanical behaviours of the geomaterials, and provide the scientific insights enabling for better engineering. Discontinuous numerical methods are indeed very much research and engineering tools of the present, and certainly more in the future. Advances in Discontinuous Numerical Methods and Applications in Geomechanics and Geoengineering is a collection of 55 technical papers presented at the 10th International Conference on Analysis of Discontinuous Deformation (ICADD-10), held 6-8 December 2011, Honolulu, USA. The papers cover a wide scope of discontinuous numerical methods from algorithms and mechanics, to modelling techniques and applications, including the key block theory, the discontinuous deformation analysis, the numerical manifold method, the distinct element method, coupled discontinuum and continuum methods, multi-scale and multi-physics in modelling, applications and case studies of engineering projects.

Rock dynamics studies the response of rock materials and rock masses under dynamic loading conditions. In the last a couple of decades, the development of experimental and computational techniques has been able to capture the progress of fracturing in microsecond steps, allowing the exploration on how the fracture is initiated, propagated and branched, leading to the development of new scientific theories. A summary of these developments on rock dynamic testing, modeling and theory will help the scientific and engineering community to consolidate the understanding of rock dynamics and to apply the knowledge to practice.Rock Dynamics and Applications – State of the Art reviews the state-of-the-art of rock dynamics scientific research and engineering applications. The 77 technical papers, including 13 keynotes cover dynamics theory and numerical modelling, laboratory testing and field observation, engineering design and case study, focus on the dynamic aspects of rock mechanics and rock engineering. The book will be useful to academics and engineers interested in rock dynamics and its applications in rock mechanics and rock engineering.

Rock Dynamics: From Research to Engineering is a collection of the scientic and technical papers presented at the Second International Conference on Rock Dynamics and Applications (RocDyn-2, Suzhou, China, 18-19 May 2016). The book has four sections. The first section contains 8 keynote papers, covering a wide range of dynamic issues related to rock mechanics and rock engineering, from rock failure mechanism and stress wave propagation to seismic behaviour and impact. Section 2 includes papers on rock dynamic theory and numerical modelling, focussing on theoretical aspects of rock fracture dynamics, wave propagation, numerical methods and numerical modelling works. Papers on laboratory testing and experimental techniques are collected in Section 3, including new testing facilities, data monitoring and data analysis. Section 4 deals with case studies and engineering applications, and presents state-of-the-art papers on rock engineering related to dynamic conditions such as earthquake and blasting.

At present, deep earth resources remain poorly understood and entirely under-utilised. There is a growing appreciation of the important role deep earth will play in future sustainability, particularly in opportunities for new and sustainable large-scale energy alternatives, and extraction of resources through mining and greenhouse mitigation. Deep Rock Mechanics: From Research to Engineering is a collection of papers on the effective development of deep earth resources, which were presented at the International Conference on Geo-mechanics, Geo-Energy and Geo-Resources 2018 (Chengdu, P.R. China, 22-24 September 2018). The contributions aim at breaking beyond existing patterns of discovery, to advance research on geomechanical and geophysical processes in deep earth resources and energy development, enhancing deep earth energy and mineral extraction and mitigating harmful atmospheric emissions.Deep Rock Mechanics: From Research to Engineering covers a wide range of topics:1. Deep rock mechanics and mining theory2. Water resources development and protection3. Unconventional oil and gas extractions4. CO2 sequestrations technologies and nuclear waste disposal5. Geothermal energy6. Mining engineering7. Petroleum engineering8. Geo-environmental engineering9. Civil geotechnical engineeringDeep Rock Mechanics: From Research to Engineering promotes safer and greener ways for energy and resource production at great depth, and will serve as a must-have reference for academics and professionals involved or interested in geo-mechanics, geo-energy, and geo-resources.
