Opis

This cross-disciplinary work offers an exceptionally relevant examination of those aspects of earth science dealing with seismic behavior of fractured media. It delivers a lucid exploration of rock mechanics, examining the strengths and weakness of structures beneath the earth's immediate surface. Deliberately non-mathematical and phenomenological in nature, this volume reviews examples of seismic measurements from various fields under widely varied conditions, supported by a wealth of figures drawn from a broad review of the literature. The last chapters delve into deeper, higher stress, and large scale applications, specifically fractured petroleum reservoirs and earthquake source zone interpretation.

O autorze

Nick Barton has over 40 years of international experience in rock engineering, and has been involved in numerous important and iconic tunnel, cavern and rock slope projects. He has developed many tools and methods, such as the widely used Q-system, for rock classification and support selection and the Barton-Bandis constitutive laws for rock joint computer modeling. He currently teaches at the University of São Paulo and manages an international consultancy (Nick Barton & Associates, São Paulo – Oslo). Dr. Nick Barton was the 2011 recipient of the distinguished Müller Award, an award that honours the memory of Professor Leopold Müller, the founder of the ISRM (International Society of Rock Mechanics), and awarded in recognition of distinguished contributions to the profession of rock mechanics and rock engineering.
