This book was released on 2014-07-25 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of ISRM suggested methods for testing or measuring properties of rocks and rock masses both in the laboratory and in situ, as well as for monitoring the performance of rock engineering structures. The first collection (Yellow Book) has been published in 1981. In order to provide access to all the Suggested Methods in one volume, the ISRM Blue Book was published in 2007 (by the ISRM via the Turkish National Group) and contains the complete set of Suggested Methods from 1974 to 2006 inclusive. The papers in this most recent volume have been published during the last seven years in international journals, mainly in Rock Mechanics and Rock Engineering. They offer guidance for rock characterization procedures and laboratory and field testing and monitoring in rock engineering. These methods provide a definitive procedure for the identification, measurement and evaluation of one or more qualities, characteristics or properties of rocks or rock systems that produces a test result.

Download or read book Development of Equipment for Determining Deformation Modulus and In Situ Stress by Means of Large Flatjacks written by BP. Boisen and published by . This book was released on 1970 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of equipment and proposed procedure for determining deformation modulus and in situ stress in rock masses is discussed. The procedure, which involves the use of large flatjacks, when perfected, will be considerably more economical than conventional, more elaborate methods such as the pressure chamber method, radial jacking, and the like. The flatjack procedure involves the cutting of a slot in the rock mass by means of a hydraulically powered 3-ft-diameter diamond saw, insertion of the large 3 by 6-ft flatjacks, and pressurizing of the jacks until cancellation is reached. The system has an advantage over conventional flatjack usage in that it permits pressurizing (testing) larger areas of rock, eliminates the need for grouting the flatjacks, and permits the determination of deformation modulus in addition to in situ stress.

Download or read book Numerical Validation and Refinement of Empirical Rock Mass Modulus Estimation written by Colin David Hume and published by . This book was released on 2011 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sound understanding of rock mass characteristics is critical for the engineering prediction of tunnel stability and deformation both during construction and post-excavation. The rock mass modulus of deformation is a necessary input parameter for many numerical analysis methods to describe the constitutive behavior of a rock mass. Tests for determining this parameter directly by in situ test methods are inherently difficult, time consuming and expensive, and these challenges are more problematic when dealing with tunnels in weaker, softer rock masses where errors in modulus (stiffness) estimation have a profound impact on closure predictions. In addition, rock masses with modest structure can be candidate sites for highly sensitive structures such as nuclear waste repository tunnels. For these generally stiffer rock masses, the correct modulus assessment is essential for prediction of thermal response during the service life of the tunnel. Numerous empirical relationships based on rock mass classification schemes have been developed to determine rock mass deformation modulus in response to these issues. The empirical relationship provided by Hoek & Diederichs (2006) based on Geological Strength Index (GSI) has been determined from a database of in situ test data describing a wide range of rock masses with GSI values greater than 25 and less than 80. Within this range of applications there is a large variation in measured values compared to the predicted relationship and predictive uncertainty at low GSI values. In this research, a practical range of rock mass quality, as defined by GSI, including "Blocky\Disturbed\Seamy" rock masses, "Very Blocky" and relatively competent rock masses are analyzed using discretely fractured numerical models. In particular the focus is on tunnel response. Tunnel closure in these simulations is compared to predictions based on modulus estimates. The proposed refinement to the Generalized Hoek-Diederichs relationship is made on the basis of these simulations for tunnelling applications.
Download or read book Engineering Properties of Rocks written by Lianyang Zhang and published by Butterworth-Heinemann. This book was released on 2016-09-06 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
