This book was released on 1976 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes solutions to a class of dynamic elastoplastic problems that model some of the salient features of the response of hardened underground facilities in rock. The theoretical model consisted of multilayered concentric cylinders of elastoplastic materials with time-dependent loads applied to the exterior boundary. Each element in the cross section was assumed to be incompressible and its yield governed by a Mohr-Coulomb failure criterion. The number of elements within the cross section was not limited. Solutions of the theoretical model were cast in the general form normally used in structural dynamics: Mass x Acceleration = External applied load - Internal resistance. The resulting equations can be quickly and inexpensively evaluated on a digital computer. To extend the range of validity of the exact theory, a first-order correction factor was developed to account for the compressibility of the materials, and a simple method to treat backpacked structures was introduced. The theory was verified by comparing calculated values with experimental measurements from small-scale static and explosively driven tunnel collapse studies. Good agreement was noted for all cases considered. (Author).

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the international edition of the proceedings of IS-Seoul 2011, the Fifth International Symposium on Deformation Characteristics of Geomaterials, held in Seoul, South Korea, in September 2011.The book includes 7 invited lectures, as well as 158 technical papers selected from the 182 submitted. The symposium explored ideas about the complex load-deformation response in geomaterials, including laboratory methods for small and large strains; anisotropy and localization; time-dependent responses in soils; characteristics of treated, unsaturated, and natural geomaterials; applications in field methods; evaluation of field performance in geotechnical structures; and physical and numerical modeling in geomechanics. These topics were grouped under a number of main themes, including experimental investigations from very small strains to beyond failure; behavior, characterization and modeling of various geomaterials; and practical prediction and interpretation of ground response: field observation and case histories. Both the symposium and this book represent an important contribution to the exchange of advanced knowledge and ideas in geotechnical engineering and promote partnership among participants worldwide.
Download or read book Earthquake Geotechnical Engineering Design written by Michele Maugeri and published by Springer Science & Business Media. This book was released on 2014-02-03 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pseudo-static analysis is still the most-used method to assess the stability of geotechnical systems that are exposed to earthquake forces. However, this method does not provide any information about the deformations and permanent displacements induced by seismic activity. Moreover, it is questionable to use this approach when geotechnical systems are affected by frequent and rare seismic events. Incidentally, the peak ground acceleration has increased from 0.2-0.3 g in the seventies to the current value of 0.6-0.8 g. Therefore, a shift from the pseudo-static approach to performance-based analysis is needed. Over the past five years considerable progress has been made in Earthquake Geotechnical Engineering Design (EGED). The most recent advances are presented in this book in 6 parts. The evaluation of the site amplification is covered in Part I of the book. In Part II the evaluation of the soil foundation stability against natural slope failure and liquefaction is treated. In the following 3 Parts of the book the EGED for different geotechnical systems is presented as follows: the design of levees and dams including natural slopes in Part III; the design of foundations and soil structure interaction analysis in Part IV; underground structures in Part V. Finally in Part VI, new topics like the design of reinforced earth retaining walls and landfills are covered.
