This text book provides the theoretical background of rock fracture mechanics and displacement discontinuity methods used for the modelling of geomechanical problems. The computer program FRACOD is used to analyse the fracture problems, assessing fracture initiation and propagation in tension (Mode I), shear (Mode II) and mixed mode I and II of solid intact or jointed geomaterials. The book also presents the fundamentals of thermo-mechanical coupling and hydro-mechanical coupling. Formulations of multiple regional mechanical, thermal and hydraulic functions, which allow analyses of fracture mechanics problems for structures made of brittle, rock-like materials, are provided. In addition, instructive examples of code verification and applications are presented. Additional material: The 2-D version of the FRACOD program, a manual on the program and a wealth of verification examples of classical problems in physics, mechanics and hydromechanics are available at http://extras.springer.com. A large number of applications related to civil, mining, petroleum and environmental engineering are also included. - The first textbook available on modelling of rock fracture propagation - Introduces readers to the fundamentals of rock fracturing - Uses a modern style of teaching with theory, mathematical modelling and applications in one package - The basic version of the FRACOD software, manual, verification examples and applications are available as additional material - The FRACOD program and manual enable the readers to solve fracture propagation problems on their own --------------------------- Ki-Bok Min, Department of Energy Resources Engineering, College of Engineering, Seoul National University, Korea “Challenging rock engineering applications require extreme conditions of stress, temperature and hydraulic pressure resulting in rock fracturing to a various extent. The FRACOD is one of few computer codes available in engineering rock mechanics that can simulate the initiation and propagation of fractures often interacting with natural fractures. Its capability has been significantly enhanced to include the hydraulic and thermal fracturing with concerted interaction from multi-national research and industry partners. My experience with the FRACOD is very positive and I am certain that its already-excellent track record will expand further in the future."

This book describes a unique approach using the principles of rock fracture mechanics to investigate the behaviour of fractured rock masses for rock engineering purposes. Rock fracture mechanics, a promising outgrowth of rock mechanics and fracture mechanics, has developed rapidly in recent years, driven by the need for in-depth understanding of rock mass failure processes in both fundamental research and rock engineering designs. Today, as rock engineering extends into many more challenging fields (like mining at depth, radioactive waste disposal, geothermal energy, and deep and large underground spaces), it requires knowledge of rock masses, complex coupled thermalhydraulicchemicalmechanical processes. Rock fracture mechanics play a crucial role in these complex coupled processes simply because rock fractures are the principal carrier and common interface. To date, the demand for rock fracture mechanicsbased design tools has outstripped the very limited number of numerical tools available.

Hydraulic fracturing is a well-stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand and other proppants suspended with the aid of gelling agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. This book describes a unique approach using the principles of rock fracture mechanics to investigate the behaviour of fractured rock masses for rock engineering purposes. Rock fracture mechanics, a promising outgrowth of rock mechanics and fracture mechanics, has developed rapidly in recent years, driven by the need for in-depth understanding of rock mass failure processes in both fundamental research and rock engineering designs.

"The study of rock fracturing is a fundamental research topic in rock mechanics and engineering. Discrete element methods are proven to be very capable for describing fracturing and fragmentation processes because, much like real rocks, the numerical materials are composed of assemblages of particles. Nonetheless, correlation macromechanical behaviour to the corresponding origin at the microscale is scarce in the literature. In this study, a systematic analysis is carried out to investigate failure mechanisms taking place in rock mass with special emphasis put on macroscopic deformation processes and the micromechanical origin. Detailed inspection of fracturing behavior of jointed rock mass at the laboratory-scale can allow the implication of the acquired fundamental knowledge of rock fracturing development and failure mechanism extend to the large-scale rock slope instability problems. This thesis is devoted to gain a comprehensive understanding regarding the rock deformation from laboratory‐scale experiments to large‐scale geodynamic processes that leads to an improved design for rock engineering projects.The research results have been submitted or published in refereed journals amounting to 3 journal papers. These papers are compiled to produce 6 chapters in this manuscript-based thesis. The investigation of damage evolution and failure characteristic of rock mass with increased density of initial jointing subjected to confined stress state is first conducted using discrete element method (DEM) to provide a micromechanical description of the mechanisms involved and foster an accurate interpretation and prediction on rock instabilities for advancing the understanding of rock fracturing process during landslide propagation. The rest of the thesis is devoted to modeling the progressive slope failure under seismic loading via discrete element method, aiming to provide new insights into the detailed microresponses and macroresponses of coseismic landslides. Replication of the natural system, the calibration procedure to determine the properties of the discrete elements is in essence for a reasonable numerical simulation, in particular, boundary condition. Thus, quite boundary is used to ensure the seismic wave cannot reflect back to the model. The developed discrete element framework is used to investigate complex dynamic responses of rock slopes, including internal rock damage, energy conversion, dynamic disintegration, and fragment runout. The results of the numerical analysis are compared with field data. The characteristics of dynamic rock fragmentation and the mechanism governing the postfailure fragmented landsliding motions is investigated and displacements, stresses, fracturing behaviour, solid fraction, and fragmentation and fragment shape developing within the transport of rock mass are analyzed. Conclusions and recommendations are made regarding the dynamic rock fragmentation and the mechanisms governing the transport kinematics of seismic-induced landslides"--

Fractured rock is the host or foundation for innumerable engineered structures related to energy, water, waste, and transportation. Characterizing, modeling, and monitoring fractured rock sites is critical to the functioning of those infrastructure, as well as to optimizing resource recovery and contaminant management. Characterization, Modeling, Monitoring, and Remediation of Fractured Rock examines the state of practice and state of art in the characterization of fractured rock and the chemical and biological processes related to subsurface contaminant fate and transport. This report examines new developments, knowledge, and approaches to engineering at fractured rock sites since the publication of the 1996 National Research Council report Rock Fractures and Fluid Flow: Contemporary Understanding and Fluid Flow. Fundamental understanding of the physical nature of fractured rock has changed little since 1996, but many new characterization tools have been developed, and there is now greater appreciation for the importance of chemical and biological processes that can occur in the fractured rock environment. The findings of Characterization, Modeling, Monitoring, and Remediation of Fractured Rock can be applied to all types of engineered infrastructure, but especially to engineered repositories for buried or stored waste and to fractured rock sites that have been contaminated as a result of past disposal or other practices. The recommendations of this report are intended to help the practitioner, researcher, and decision maker take a more interdisciplinary approach to engineering in the fractured rock environment. This report describes how existing tools-some only recently developed-can be used to increase the accuracy and reliability of engineering design and management given the interacting forces of nature. With an interdisciplinary approach, it is possible to conceptualize and model the fractured rock environment with acceptable levels of uncertainty and reliability, and to design systems that maximize remediation and long-term performance. Better scientific understanding could inform regulations, policies, and implementation guidelines related to infrastructure development and operations. The recommendations for research and applications to enhance practice of this book make it a valuable resource for students and practitioners in this field.

Rock fractures control many of Earth's dynamic processes, including plate-boundary development, tectonic earthquakes, volcanic eruptions, and fluid transport in the crust. An understanding of rock fractures is also essential for effective exploitation of natural resources such as ground water, geothermal water, and petroleum. This book combines results from fracture mechanics, materials science, rock mechanics, structural geology, hydrogeology, and fluid mechanics to explore and explain fracture processes and fluid transport in the crust. Basic concepts are developed from first principles and illustrated with worked examples linking models of geological processes to real field observations and measurements. Many additional examples and exercises are provided online, allowing readers to practise formulating and quantitative testing of models. Rock Fractures in Geological Processes is designed for courses at the advanced undergraduate and graduate level but also forms a vital resource for researchers and industry professionals concerned with fractures and fluid transport in the Earth's crust.
