Engineering in Rock Masses is a 26-chapter text that deals with the behavior, investigation, and construction of rock masses. The first chapters review the properties, behavior, classification, and occurrence of groundwater in rock masses. The subsequent chapters discuss the stress analysis, exploration, laboratory testing, geophysical methods, and instrumentation in these materials. These topics are followed by discussions of slope stability, rockfall problems, settlement and bearing capacity, subsidence, and seismic movements of rocks and rock masses. This work also evaluates the role of pumping system, ground freezing, grouting, rock anchors, drilling, blasting, and open excavation. The remaining chapters look into the rock masses’ tunneling, underground chambers, shafts, socketed foundations, and retaining structures. This book will be of great value to practicing civil and mining engineers, engineering geologists, and researchers.

Geotechnical descriptors for rock and rock mass are suggested for use in the field that can be readily understood by geotechnical engineers and contractors. Geotechnical applications include tunnel support. slope and foundation stability, and rock excavation. The descriptors are rock type, strength, discontinuity characterization, weathering, rock quality designation (RQD), ground-water conditions, and rock density. The rock name or type should be retained in field description but uncommon rock names should be accompanied by a brief definition to enable the user to relate to more common rock types. Rock strength should be described quantitatively by the point load index test. Descriptions of discontinuities should include measurement and classification of aperture and a determination of whether the discontinuity is open or tight; filling thickness and composition; wall asperity or roughness; and orientation of individual discontinuities; sets and systems. Use of stereographic projection and unambiguous azimuthal notation to describe discontinuity orientation is recommended. Bieniawski's classification of rock weathering is recommended. Field recognition and description of seepage and groundwater conditions along discontinuities based on simple observations of the amount of water present and estimates of discharge are recommended to precede and augment the design of more elaborate pore pressure and seepage analysis investigations.

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.

Rock mass classification methods are commonly used at the preliminary design stages of a construction project when there is very little information. It forms the bases for design and estimation of the required amount and type of rock support and groundwater control measures. Encompassing nearly all aspects of rock mass classifications in detail, Civil Engineering Rock Mass Classification: Tunnelling, Foundations and Landsides provides construction engineers and managers with extensive practical knowledge which is time-tested in the projects in Himalaya and other parts of the world in complex geological conditions. Rock mass classification is an essential element of feasibility studies for any near surface construction project prior to any excavation or disturbances made to earth. Written by an author team with over 50 years of experience in some of the most difficult mining regions of the world, Civil Engineering Rock Mass Classification: Tunnelling, Foundations and Landsides provides construction engineers, construction managers and mining engineers with the tools and methods to gather geotechnical data, either from rock cuts, drifts or core, and process the information for subsequent analysis. The goal is to use effective mapping techniques to obtain data can be used as input for any of the established rock classification systems. The book covers all of the commonly used classification methods including: Barton’s Q and Q’ systems, Bieniawski’s RMR, Laubscher’s MRMR and Hoek’s and GSI systems. With this book in hand, engineers will be able to gather geotechnical data, either from rock cuts, drifts or core, and process the information for subsequent analysis. Rich with international case studies and worked out equations, the focus of the book is on the practical gathering information for purposes of analysis and design. Identify the most significant parameters influencing the behaviour of a rock mass Divide a particular rock mass formulation into groups of similar behaviour, rock mass classes of varying quality Provide a basis of understanding the characteristics of each rock mass class Relate the experience of rock conditions at one site to the conditions and experience encountered at others Derive quantitative data and guidelines for engineering design Provide common basis for communication between engineers and geologists

Rock mechanics is a first course in the field of mining and geotechnical engineering. Over the last decades, the concepts and applications of rock mechanics have evolved tremendously for understanding the stability and safety of structures made of/on the rock masses. This book elaborates the fundamental concepts of rock mechanics for designing and analysis of structures and excavations for a variety of applications. The text includes a fine blend of theory and worked-out examples and applications, and also emphasises the basics of stress and strain analysis, volume–weight relationship, rock mass classification systems, in situ stress measurements, stresses around underground opening, pillar and support design, subsidence, slope stability, rock failure criteria and behaviour of jointed rock mass. Numerical analysis procedures and interaction between rock bolts and rock masses are also introduced emphasising the mechanics and applications in rock engineering. Besides undergraduate and postgraduate students of civil (including geotechnical), mining and petroleum engineering, the book will also benefit the practicing engineers and researchers, who wish to acquaint themselves with state-of-the-art techniques of rock mechanics and its applications. Overall, this textbook is useful for both elementary as well as advanced learning.

Until a few years ago, hydropower, road tunneling and mining were the main fields interested in rock mechanics. Now, however, rock mechanics is becoming increasingly important in many more branches - the most significant globally being the disposal of hazardous, especially radiaoctive, waste in deeply located repositories. This has raised a number of new aspects on the mechanical behaviour of large rock masses hosting repositories and of smaller rock elements forming the nearfield of tunnels and boreholes with waste containers. The geological background and above all rock structure form the basis of this book. The structural scheme proposed is referred to explain the scale-dependent behaviour of rock. Thus, the reason for differences in strength and strain properties of different types and volumes of rocks is shown in a very clear fasion, using simple material models and very basic numerical models. The author's academic background in both geology and soil and rock mechanics and his long experience in practical design and construction work has led to an unusually pedagogic way of dealing with the subject. The book is intended for use by consultants in engineering geology and waste disposal and by students of these subjects. However, engineers and geologists with a limited background in stress/strain and fracture theory and computer-based calculation methods will also find the book attractive.
