This book has been designed to provide a fundamental knowledge of the geological structure and properties of rocks and rock masses. It sets out laboratory and field methods for examining these media, presents physical and mechanical models used in their description, and reviews geotechnical classifications, discussing their use in solving various engineering tasks. Three basic problems of rock mechanics are discussed, namely, the distribution of stresses, the criteria and mechanisms of failure in rocks and rock masses, and the hydraulics of water flow in rock masses, together with effects associated with this flow. Attention is also paid to methods for solving basic engineering problems related to the behaviour of the bedrock on which various hydrostructures have been founded, are planned to be founded, or are in the process of being constructed. A prominent feature of the book is its methodical approach. It offers a sympathetic survey of the problems involved and enables the reader to select, according to the adopted criteria, an appropriate method for the solution of the engineering problem at hand by following the ready-to-use procedure included. In addition, numerous drawings, abundant tabulated data, and an extensive bibliography, permits the reader to gain a deeper knowledge of the problems under consideration. The book will be of interest to those concerned with hydrotechnical projects, lecturers and students in higher technical schools, and researchers investigating the problems of rock mechanics.

Soils, rocks and concrete are the principal materials a civil engineer encounters in practice. This book deals with the material analogies, their implications in property characterization, giving attention to similar as well as dissimilar methods in respect of each of these three materials. It provides an integrated, systematic approach for realistic assessment of engineering properties of soils, rocks and concrete. Geotechnical engineers, civil engineers and materials scientists will be interested in this volume.

During the last ten years, our understanding of the perfect plasticity and the associated flow rule assumption on which limit analysis is based has increased considerably. Many extensions and advances have been made in applications of limit analysis to the area of soil dynamics, in particular, to earthquake-induced slope failure and landslide problems and to earthquake-induced lateral earth pressures on rigid retaining structures. The purpose of the book therefore is in part to discuss the validity of the upper bound work (or energy) method of limit analysis in a form that can be appreciated by a practicing soil engineer, and in part to provide a compact and up-to-date summary of recent advances in the applications of limit analysis to earthquake-induced stability problems in soil mechanics.

Surface subsidence is recognised as a problem in most countries, particularly those with significant mining and other underground resource extraction industries. This book addresses the problems relating to subsidence whether caused naturally, or arising from mining or other forms of underground extractive activity. The main purpose of this book is to bring together subsidence knowledge, experiences and research findings in many countries and rationalise such information especially in respect of its particular field of application. Emphasis has been given to collating field data on subsidence from different countries in order to make direct comparisons. Prediction of subsidence, particularly its occurrence and general characteristics has been seen as an important area where the book can contribute significantly in terms of reviewing available knowledge, methods, scope of application and orders of accuracy achieved. The book also examines methods of controlling subsidence and discusses the response of surface structures to and protection against subsidence.

Die Deutsche Bodenmechanik Tagung etabliert sich nach ihrer gelungenen Auftaktveranstaltung vor zwei Jahren zum Forum für fachlichen Austausch und zur Diskussion aktueller Fragestellungen. Der vorliegende zweite Tagungsband behandelt diese aktuellen Themen: „Stoffgesetze und Materialverhalten", „Boden als Mehrphasensystem" und „Anwendungsbezogene Herausforderungen in der Bodenmechanik". Die Tagung wurde vom Lehrstuhl für Grundbau, Boden- und Felsmechanik der Ruhr-Universität Bochum in Kooperation mit dem Lehrstuhl Baugrund-Grundbau der TU Dortmund veranstaltet. Sie fand unter der Schirmherrschaft der Deutschen Gesellschaft für Geotechnik (DGGT) an der Ruhr- Universität in Bochum statt.

This book presents the most up to date information relevant to the design and instrumentation of underground structures. The structure might be a tunnel, shaft, cavern, or pressure unit, or a combination thereof. Empirical, rational, numerical, convergence and confinement, and discontinuity analysis methods are treated comprehensively. Special chapters are devoted to underground structures in rock burst, swelling, squeezing, and seismic zones. Water control, instrumentation, and tunneling through soft ground are also treated extensively. Sections on the design of pressure tunnels, shafts, caverns, shotcreting, water control, and soft ground tunnels are informative and authoritative. Worked examples are included on the design of rock tunnels, soft ground tunnels, and the treatment of underground structures through difficult ground. Extensive references are provided, and figures, sketches and photographs aid presentation. Important tables on planning, and case histories, allow the reader to build confidence in his design of underground structures. The book will be beneficial to civil, structural, geotechnical and mining engineers, geologists, and planners and managers associated with the design and construction of underground structures.

This volume provides a comprehensive overview on the vast amount of literature on solidification heat transfer. Chapter one develops important basic equations and discusses the validity of considering only conductive heat transfer, while ignoring convection, in the large class of materials which make up the porous media. Chapters 2 to 4 deal with problems that can be expressed in plane (Cartesian) coordinates. These problems are further divided into boundary conditions of temperature, prescribed heat flux, and surface convection. Chapter 5 examines some plane geometries involving three-dimensional freezing or thawing. Problems in the cylindrical and spherical coordinate systems are covered in chapters 6 and 7. Chapter 8 is an introduction to solidification in porous media. Many of the applications have been directed to water/ice soil-systems, but it should be clear that the basic techniques and solutions can be applied to such diverse areas as metallurgy, biological systems, latent heat storage, and the preservation of food.
