Rock mechanics is a multidisciplinary subject combining geology, geophysics, and engineering and applying the principles of mechanics to study the engineering behavior of the rock mass. With wide application, a solid grasp of this topic is invaluable to anyone studying or working in civil, mining, petroleum, and geological engineering. Rock Mechanics: An Introduction presents the fundamental principles of rock mechanics in a clear, easy-to-comprehend manner for readers with little or no background in this field. The text includes a brief introduction to geology and covers stereographic projections, laboratory testing, strength and deformation of rock masses, slope stability, foundations, and more. The authors--academics who have written several books in geotechnical engineering--have used their extensive teaching experience to create this accessible textbook. They present complex material in a lucid and simple way with numerical examples to illustrate the concepts, providing an introductory book that can be used as a textbook in civil and geological engineering programs and as a general reference book for professional engineers.
