Book excerpt: Two methods are presented for the analysis of tunnel support loading caused by rock failure. In the first part closed-form solutions are used; in the second, numerical techniques. Emphasis is put upon the statical indeterminacy of the problem and upon the necessity for considering the relative displacements between ground and support. From this follows the need for a realistic calculation of the stiffness of ground and support, as well as the need to consider the sequential development of the interaction between these two elements. It is assumed that the rock mass behavior during failure is softening and dilatant. Interface problems between ground and support that can strongly influence the effective support stiffness are discussed.

Book excerpt: When dealing with rock in civil engineering, mining engineering and other engineering, the process by which the rock fails under load should be understood, so that safe structures can be built on and in the rock. However, there are many ways for loading rock and rock can have a variety of idiosyncracies. This reference book provides engineers and r

This book was released on 2014-01-01 with total page 779 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the ever-increasing developmental activities as diverse as the construction of dams, roads, tunnels, underground powerhouses and storage facilities, petroleum exploration and nuclear repositories, a more comprehensive and updated understanding of rock mass is essential for civil engineers, engineering geologists, geophysicists, and petroleum and mining engineers. Though some contents of this vast subject are included in under-graduate curriculum, there are full-fledged courses on Rock Mechanics/Rock Engineering in postgraduate programmes in civil engineering and mining engineering. Much of the material presented in this book is also taught to geology and geophysics students. In addition, the book is suitable for short courses conducted for teachers, practising engineers and engineering geologists. This book, with contributions from a number of authors with expertise and vast experience in various areas of rock engineering, gives an in-depth analysis of the multidimensional aspects of the subject. The text covers a wide range of topics related to engineering behaviour of rocks and rock masses, their classifications, interpretation of geological mapping of joints through stereographic projection, in situ stress measurements, laboratory and field tests, stability of rock slopes, foundations of structures, including dams and support systems for underground excavations. The Third Edition of the book is further enriched with the addition of a number of case histories in which the analyses and designs were carried out by adopting rock mass parameters as per RMR, Q or GSI. The consequence of such an approach is critically examined. With the adoption of parameters from joint factor, excellent performance prediction has been demonstrated for anisotropic rocks and tunnel. Various expressions developed for Kn and Ks for different conditions are included for adoption in numerical analyses. When dilatancy component is separated, the scale effect on shear response is insignificant. This edition provides a comprehensive understanding of rock mass response and enables students to tackle rock engineering problems more confidently and realistically, and therefore it will be of immense benefit to students, teachers, professionals and designers alike.

Download or read book Support of Underground Excavations in Hard Rock written by E. Hoek and published by CRC Press. This book was released on 2000-01-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The safe and economical construction of tunnels, mines, and other subterranean works depends on the correct choice of support systems to ensure that the excavations are stable. These support systems should be matched to the characterstics of the rock mass and the excavation techniques adopted. Establishing the support requirements, designing support systems and installing these correctly are essential elements in safe underground construction. This is a comprehensive and practical work which also gives access to user-friendly computer programmes which enable the investigation and design of support techniques. Details on how to obtain this software are also included in the book.

Download or read book Tunnel Design Methods written by Antonio Bobet and published by CRC Press. This book was released on 2023-09-12 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tunnel Design Methods covers analytical, numerical, and empirical methods for the design of tunnels in soil and in rock. The material is intended for design engineers looking for detailed methods, for graduate students who are interested in tunnelling, and for researchers working on various aspects of ground-support interaction under static and seismic loading. The book is divided into seven chapters, covering fundamental concepts on ground and support behavior and on ground-excavation-support interaction and provides detailed information on analytical and numerical methods used for the design of tunnels, with applications, and on the latest developments on empirical methods. The principles and formulations included are used, throughout the book, to provide insight into the response of tunnels under both simple and complex loading conditions, thus providing the reader with fundamental understanding of tunnel behavior. Both authors have experience in tunnelling and have worked extensively in practice, designing tunnels both in the United States and abroad, and in research.
