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.

Concrete will be the key material for Mankind to create the built environment of the next millennium. The requirements of this infrastructure will be both demanding, in terms of technical performance and economy, and yet be greatly varied, from architectural masterpieces to the simplest of utilities. Specialist techniques and materials for concrete construction forms the Proceedings of the three day international conference held during the Congress, creating with concrete, 6-10 September 1999, organised by the Concrete technology unit, University of Dundee. Topics discussed include grouting, sprayed concrete, foamed concrete, underwater concrete, floor toppings and overlays and non-ferrous reinforcement.

Unlike similar titles providing general information on ground improvement, Jet Grouting: Technology, Design and Control is entirely devoted to the role of jet grouting – its methods and equipment, as well as its applications. It discusses the possible effects of jet grouting on different soils and examines common drawbacks, failures and disadvantages, recent advances, critical reviews, and the range of applications, illustrated with relevant case studies. The book addresses several topics involving this popular worldwide practice including technology issues, the interpretation of the mechanisms taking place during the grouting, the quantitative prediction of their effects, the design of jet-grouted structures, and procedures for controlling jet grouting results. Discusses the design criteria for jet grouting projects and reviews existing design rules and codes of practice of different countries Provides practical methods for design calculations of the most important jet-grouted structures such as foundations, earth retaining walls, water cut-offs, bottom plugs, and provisional tunnel supports Includes the current standard control methods and most innovative techniques reported for the implementation of quality control and quality assurance procedures Jet Grouting: Technology, Design and Control analyzes the typical jet-grouted structures, such as foundations, earth retaining walls, water cut-offs, bottom plugs and tunnel supports, and serves as a practical manual for the correct use of jet grouting technology.

Geomechanics from Micro to Macro contains 268 papers presented at the International Symposium on Geomechanics from Micro and Macro (IS-Cambridge, UK, 1-3 September 2014). The symposium created a forum for the dissemination of new advances in the micro-macro relations of geomaterial behaviour and its modelling. The papers on experimental investigations show findings from micro-scale experiments, non-destructive imaging, element testing (coarse grained materials, fine grained materials and mixtures), physical model tests and field tests. The subjects of the investigations include particle effects (shape, size and grading), partial saturation, creep and aging, fluid-grain coupling, biological and chemical effects, and thermal effects. The papers on discrete based modelling examine pre- and post-failure behaviour, particle shapes and size effects, particle crushing, dynamic behaviour, bonding effects, fracturing and fragmentation, interface behaviour, and fluid-grain coupling. The contributions on continuum based modelling include stress-strain relationships, multi-scale modelling, multiphase modelling, fluid flow modelling, and numerical modelling based on continuum based models and particle based models. Geomechanics from Micro to Macro will be of interest to academics and engineers involved in granular physics, soil mechanics, rock mechanics, geotechnical engineering and geological engineering.

Developments in Geotechnical Engineering 6: Dams, Dam Foundations, and Reservoir Sites explores the design and construction of dams and reservoirs, and the foundations on which they rest. It discusses the theory and practice of geology and geophysics as they are applied to the study of proposed sites on which to build dams and reservoirs, the measures taken to ensure the continued safety of a dam during construction, and geological processes and features of foundations. Comprised of 10 chapters, this volume begins with an overview of the geotechnical aspects of planning and construction of dams and reservoirs, along with the origin, nature, and magnitude of problems associated with the foundation materials to be used. It then looks at the geological classification of natural substances and the strengths of these substances in terms of their origin, fabric, and mineralogy; excavation and filling of valleys; the influence of geologic structure in the development of erosional and depositional features in valleys; and the flow of water (seepage) beneath dams and around abutments. The reader is also introduced to groundwater hydrology as it relates to the movement of water through anisotropic materials beneath standing or running bodies of water at the Earth's surface and beneath dams; the mechanics of dam foundations; and excavations and dam construction in unconsolidated deposits. This book will be of interest to geologists, geophysicists, and engineers, as well as those involved in hydrology, geosciences, and rock and soil mechanics.
