Available in PDF, EPUB and Kindle. Book excerpt: Rock shear strength is often determined from in situ tests. Many cases have been reported in the literature describing in situ shear test procedures and test results. The purpose of this report is to summarize this information for guidance in planning and evaluating such tests. The types of tests discussed are: direct shear test, Triaxial or multiaxial test, torsion shear test, and pull-out test. The direct shear test is most widely used, and some 48 case histories of such tests are summarized in Appendixes A through E. The main advantage of the direct shear test is the ability to measure the shear resistance in any desired direction along potentially critical discontinuities. The test is also popular due to its adaptability to field conditions; tests can be conducted in trenches, adits, tunnels, and even calyx drill holes. (Author).

Download or read book Measurement of In Situ Shear Strength Using the Torsional Shear Method written by JB. Sellers and published by . This book was released on 1974 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The torsional shear test consists of applying a torque to a cylindrical core of rock isolated from a rock mass, by means of a diamond drill. The core is restrained by means of an axial rock bolt which is used to apply a controlled normal load. The core is gripped in an apparatus and twisted with a known torque. The twist is measured and the point of failure determined. Failure occurs on a well-defined plane, which can be made to coincide with indigenous planes of weakness. Test results give the shear strength directly in terms of the cohesion and the angle of friction. Residual shear strength after prolonged sliding can also be determined.

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 In Situ Testing Methods in Geotechnical Engineering written by Alan J. Lutenegger and published by CRC Press. This book was released on 2021-05-03 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Situ Testing Methods in Geotechnical Engineering covers the field of applied geotechnical engineering related to the use of in situ testing of soils to determine soil properties and parameters for geotechnical design. It provides an overview of the practical aspects of the most routine and common test methods, as well as test methods that engineers may wish to include on specific projects. It is suited for a graduate-level course on field testing of soils and will also aid practicing engineers. Test procedures for determining in situ lateral stress, strength, and stiffness properties of soils are examined, as is the determination of stress history and rate of consolidation. Readers will be introduced to various approaches to geotechnical design of shallow and deep foundations using in situ tests. Importantly, the text discusses the potential advantages and disadvantages of using in situ tests.

Available in PDF, EPUB and Kindle. Book excerpt: This document presents state-of-the-practice information on the evaluation of soil and rock properties for geotechnical design applications. This document addresses the entire range of materials potentially encountered in highway engineering practice, from soft clay to intact rock and variations of materials that fall between these two extremes. Information is presented on parameters measured, evaluation of data quality, and interpretation of properties for conventional soil and rock laboratory testing, as well as in situ devices such as field vane testing, cone penetration testing, dilatometer, pressuremeter, and borehole jack. This document provides the design engineer with information that can be used to develop a rationale for accepting or rejecting data and for resolving inconsistencies between data provided by different laboratories and field tests. This document also includes information on: (1) the use of Geographical Information Systems (GIS) and Personal Data Assistance devices for the collection and interpretation of subsurface information; (2) quantitative measures for evaluating disturbance of laboratory soil samples; and (3) the use of measurements from geophysical testing techniques to obtain information on the modulus of soil. Also included are chapters on evaluating properties of special soil materials (e.g., loess, cemented sands, peats and organic soils, etc.) and the use of statistical information in evaluating anomalous data and obtaining design values for soil and rock properties. An appendix of three detailed soil and rock property selection examples is provided which illustrate the application of the methods described in the document.
