In this book, the authors present a review of the methods used for the solution of problems of stability and support of mine workings, based on the study and analysis of the validity conditions of individual theoretical computing procedures. The classification of these methods, based on the analysis of factors determining the behaviour of a system of mine openings, should contribute to the greater objectivity of decisions connected with the management and control of mining operations and, from the educational point of view, enable the intricate problems of stability to be better understood. Chapters dealing with support structures and technologies of support review the present state of the art with special reference to problems prevailing in Europe where mining is carried out under continuously deteriorating and less favourable natural conditions. The authors have assembled the theoretical and practical knowledge necessary for those to whom the book is addressed, namely, practising mining engineers and project managers, and students and graduates in mining colleges and schools.

Engineering geology is an interdisciplinary subject concerned with the application of geological science to engineering practice, and it is therefore important for the engineering geologist to recognize the boundary between engineering application and purely scientific enquiry. Much research in applied clay science results from imperfectly understood engineering behaviour. Engineering geology is most closely allied to the geotechnical and materials areas of civil engineering. The scope of the present book is limited to the influence of clay but because clay is almost ubiquitous in earth materials the subject still remains broad. In soil and rock, clay is the smallest size fraction, but it is that very fact which often determines its major influences on engineering behaviour. In this book the author reviews the importance of clay in engineering geology and summarizes present knowledge in this field. The plan of the book has remained unchanged since the first edition was published in 1968 but the text, diagrams and reference lists have all been extensively updated. The first 5 chapters review the classification, origin, composition, fabric and physical chemistry of clays. Behavioural aspects, covered in the following 4 chapters, include moisture interaction, strength and rheology, soil stabilization and the use of clays as materials. The final 3 chapters describe methods of analysis of clays and soils. Clay in Engineering Geology contains material drawn from a wide variety of sources and, together with its literature review and indexes, will provide much of value to geologists, mineralogists, civil and geotechnical engineers concerned with applied clay science.

Lifeline earthquake engineering is the application of all relevant knowledge and skill to provide economically feasible engineering safeguards for critical systems such as energy, transportation, water, power, communications, etc. Natural gas and oil pipelines, water and sewage lines, oil and gas storage facilities, tunnels, power, voice and data communication lines and equipment are some of the recognized examples in this relatively new area of interest which has attracted an ever-increasing number of researchers in the past few years. This volume contains most of the papers on lifeline earthquake engineering which were presented at the Third International Conference on Soil Dynamics and Earthquake Engineering, Princeton University, Princeton, New Jersey, USA, 22-24 June 1987. A number of recent major developments in analytical/experimental investigations and field observations for buried pipelines, underground structures and storage tanks were presented by some of the leading experts from the United States, Japan and China.

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.

Since the publication of the first Dams and Earthquakes in 1976, the phenomenon of reservoir induced seismicity (RIS) is more widely understood. There are now over 70 known cases of reservoir-induced earthquakes. These damaging earthquakes have occurred in China, Kariba, Zambia, Greece, Kremasta, Koyna, India, California and elsewhere. The December 10, 1967 Koyna earthquake, with a magnitude of 6.3 claimed over 200 lives, injured 1500 and rendered thousands homeless. Because of the ever increasing demand for dam construction, for power generation, irrigation, and flood control, it is necessary to understand how, where and why induced earthquakes occur. Recent research has demonstrated that when suitable physical measurements of rock properties are made, a fairly accurate model of induced seismicity can be obtained. It appears possible to mitigate the hazard of RIS through manipulation of reservoir levels. The present volume is an updated and revised follow-up to the 1976 book. It presents an overview of the world-wide distribution of RIS, the salient aspects of RIS at specific reservior sites where earthquakes of M〉5 have occurred and where new results on RIS are reported, and how they differ from the normal earthquake sequences. An examination of the non-occurrence of induced earthquakes in the vicinity of the Himalyan reservoirs and other related topics such as: the size of the largest induced earthquake that could occur at a given reservoir site; prediction of induced earthquakes; and dam site investigations which should be completed during the planning and operation of the reservoirs are also included.

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.

Grouting is a construction process by means of which the highly erratic permeability and deformability of foundation rock and soil are homogenized. The main parameter governing the design and construction of grouting works is the permeability of the rock or soil, which is established by means of field permeability tests. This book assembles information on rock and soil grouting from various sources, together with the author's personal experience on several grouting projects. Some aspects of permeability testing of rock and soils are elaborated, and the use of theoretical ground water percolation studies for clarification of design options for grout curtains are presented. The results achieved by grouting are presented and analysed on examples of constructed grouting works (curtains, tunnels, foundations, lifting of structures). Particulars of the performance of the permeability tests and their evaluation are studied in some detail, since they can very much distort the results obtained, and thus lead to erroneous design assumptions. Systematic grouting and adjustment of the injection process to the development of grout consumption and pressure during injection is discussed in connection with the achievement of the required permeability standard. The application of grouting to reduce the permeability and the deformability of the foundation of dams and hydrotechnical structures is presented, together with a number of illustrative examples. Characteristics of contact and consolidation grouting of dam foundations and tunnel linings are described. The possibilities and examples of rock prestressing by means of grouting are reported, and the results from several applications are discussed. Examples of lifting and levelling leaning structures by means of grouting are also reviewed. The book is illustrated by 180 drawings and 20 photographs, and a list of symbols used in the formulae, plus a glossary of specific terms used in grouting, are included at the end of the book. The book is intended for organizations, civil engineers and geologists involved in the exploration, design, construction and supervision of large dams, hydroelectric power projects, tunnels and other underground works. Teachers and students of civil engineering courses in geotechnics, building and construction, rock mechanics, soil mechanics, engineering geology, and some aspects of mining engineering will also find the book useful.
