Book Description
Engineers wishing to build structures on or in rock use the discipline known as rock mechanics. This discipline emerged as a subject in its own right about thirty five years ago, and has developed rapidly ever since. However, rock mechanics is still based to a large extent on analytical techniques that were originally formulated for the mechanical design of structures made from man made materials. The single most important distinction between man-made materials and the natural material rock is that rock contains fractures, of many kinds on many scales; and because the fractures - of whatever kin- represent breaks in the mechanical continuum, they are collectively termed 'discontinuities' . An understanding of the mechanical influence of these discontinuities is essential to all rock engineers. Most of the world is made of rock, and most of the rock near the surface is fractured. The fractures dominate the rock mass geometry, deformation modulus, strength, failure behaviour, permeability, and even the local magnitudes and directions of the in situ stress field. Clearly, an understanding of the presence and mechanics of the discontinuities, both singly and in the rock mass context, is therefore of paramount importance to civil, mining and petroleum engineers. Bearing this in mind, it is surprising that until now there has been no book dedicated specifically to the subject of discontinuity analysis in rock engineering.

Book Description
More often than not, it is difficult or even impossible to obtain directly the specific rock parameters of interest using in situ methods. The procedures for measuring most rock properties are also time consuming and expensive. Engineering Properties of Rocks, Second Edition, explores the use of typical values and/or empirical correlations of similar rocks to determine the specific parameters needed. The book is based on the author's extensive experience and offers a single source of information for the evaluation of rock properties. It systematically describes the classification and characterization of intact rock, rock discontinuities, and rock masses, and presents the various indirect methods for estimating the deformability, strength, and permeability of these components as well as the in situ rock stresses. - Presents a single source for the correlations on rock properties - Saves time and resources invested on in situ testing procedures - Fully updated with current literature - Expanded coverage of rock types and geographical locations

Book Description
This is the first authoritative reference on rock mass classification, consolidating into one handy source information once widely scattered throughout the literature. It includes new, previously unpublished material and case histories, presents the fundamental concepts of classification schemes, and critically appraises their practical application in industrial projects such as tunneling and mining.

Book Description
Twenty years of experience is now available in the use of the Rock Quality Designation (RQD) in practice. The RQD is an index of rock quality in which a modified core recovery percentage is obtained by counting only pieces of sound core 4-in. (100 mm) or greater in length of NX size or larger core diameters. Experience now indicates both smaller (NQ) and larger core diameters are appropriate; that slightly and moderately weathered core that can not be hand broken be included; that length measurements be made along the center-line or axis of the core piece; and that the requisite length of 4-in. (100 mm) be retained. Problems with core breakage and loss occur in thinly bedded and schistose rocks, and, particularly, with weak argillaceous rock interbedded with harder sandstone or limestone, a problem that can be ameliorated by large diameter cores, shorter coring runs, and by use of the best drilling equipment and techniques. Correlations of RQD with certain engineering parameters are given, but the more recent classification system of Bieniawski or Barton et al, which include the RQD as a parameter, are preferred for estimating the design and construction parameters. For obtaining the RQD, the best drilling techniques and prompt core logging in the field by a qualified engineering geologist or geotechnical engineer should be used. The RQD is not a design parameter that stands alone, but must be used together with an appreciation of the detailed geology and the geotechnical aspects. (FR).

Book Description
Rock mass classification methods are commonly used at the preliminary design stages of a construction project when there is very little information. It forms the bases for design and estimation of the required amount and type of rock support and groundwater control measures. Encompassing nearly all aspects of rock mass classifications in detail, Civil Engineering Rock Mass Classification: Tunnelling, Foundations and Landsides provides construction engineers and managers with extensive practical knowledge which is time-tested in the projects in Himalaya and other parts of the world in complex geological conditions. Rock mass classification is an essential element of feasibility studies for any near surface construction project prior to any excavation or disturbances made to earth. Written by an author team with over 50 years of experience in some of the most difficult mining regions of the world, Civil Engineering Rock Mass Classification: Tunnelling, Foundations and Landsides provides construction engineers, construction managers and mining engineers with the tools and methods to gather geotechnical data, either from rock cuts, drifts or core, and process the information for subsequent analysis. The goal is to use effective mapping techniques to obtain data can be used as input for any of the established rock classification systems. The book covers all of the commonly used classification methods including: Barton's Q and Q' systems, Bieniawski's RMR, Laubscher's MRMR and Hoek's and GSI systems. With this book in hand, engineers will be able to gather geotechnical data, either from rock cuts, drifts or core, and process the information for subsequent analysis. Rich with international case studies and worked out equations, the focus of the book is on the practical gathering information for purposes of analysis and design. - Identify the most significant parameters influencing the behaviour of a rock mass - Divide a particular rock mass formulation into groups of similar behaviour, rock mass classes of varying quality - Provide a basis of understanding the characteristics of each rock mass class - Relate the experience of rock conditions at one site to the conditions and experience encountered at others - Derive quantitative data and guidelines for engineering design - Provide common basis for communication between engineers and geologists
