Rock Fracture: Theories, Modeling Methods, and Engineering Applications explores the principles and advanced techniques used to understand and predict rock fracture behavior. Sections discuss the theoretical framework of fracture mechanics, examining how factors like T-stress influence brittle rock failure under various loading conditions, including compression and tension. It then discusses various modeling approaches for crack propagation, such as fracture mechanics criteria, localized stress models, and their applications to different rock specimens and fault configurations. Hydraulic fracturing theories, including numerical models for fracture initiation and propagation around boreholes, along with the effects of end friction and jointed rock mass failure are also addressed.
Finally, the book investigates the progressive failure of rock slopes, emphasizing the importance of numerical simulations to anticipate failure modes like toppling and shear failure. This comprehensive treatment underscores the importance of combining theoretical understanding with modeling techniques to optimize engineering practices. Ultimately, this book offers valuable insights for researchers and engineers committed to safer and more efficient rock engineering solutions.
