Scale-Size and Structural Effects of Rock Materials presents the latest research on the scale-size and structural effects of rock materials, including test methods, innovative technologies, and applications in indoor testing, rock mechanics and rock engineering. Importantly, the book explains size-dependent failure criteria, including the multiaxial failure and Hoek-Brown failure criterion. Five chapters cover the size effect of rock samples, rock fracture toughness, scale effects of rock joints, microseismic monitoring and application, and structural effects of rock blocks. The book reflects on the scientific and technical challenges from extensive research in Australia and China.
The title is innovative, practical and content-rich. It will be useful to mining and geotechnical engineers researching the scale-size and structural effects of rock materials, including test methods, innovative technologies and applications in indoor testing, rock mechanics, and engineering, and to those on-site technical specialists who need a reliable and up to date reference.
