Available in PDF, EPUB and Kindle. Book excerpt: Fifteen years have passed since I was working at a dam site super vising grouting work. That was not the first time that I had to car ry out engineering geological investigations for several similar projects, which always included testing programmes to find out the permeability of the rock, and often I was in charge of grouting work. It thus attracted my attention when this particular grouting programme did not run as intended: most of the grout holes took only very little grout! It could not be the aim of the invested work simply to drill holes and fill them again without bringing about any further improvement. Fortunately, I had the chance to be en gaged in many other grouting programmes in the following years and used all these examples to analyse as thoroughly as possible the permeability of the rocks being treated in view of their grout ability. The more I studied, the stronger my conviction grew that our rules which had decided the grouting of rock for many de cades should be developed further, and therefore I occupied my self with contributing some ideas for a new basis to investigation and judgment of permeability of rock and for a more adequate application of this technology.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the permeability of the foundation of dams, how to determine their state and how to tighten permeable rock to achieve safe foundations for large dams. It includes theoretical fundamentals as well as lessons learned in their application in practical construction work in eminent projects. It also discusses aspects such as the permeability of the rock mass at the dam site, including the hydraulic characteristics of water conducting openings and their effect on the reliability of water pressure test (WPT) results; the influence of particular geological factors on the hydrogeological regime at the site, as well as the hydrofracturing behavior and individual groutability; and the relationship between quantities of grout takes and the degree of impermeabilization.

Download or read book Dams and Reservoirs Societies and Environment in the 21st Century written by Luis Berga and published by Taylor & Francis. This book was released on 2006-02-15 with total page 1373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resources stored by dams and reservoirs play an essential role in water resource management, hydropower and flood control. Where there is an extensive network of dam infrastructures, dams have made a major contribution to economic and social development, providing considerable storage capacity per capita. However, dams and reservoirs may also have an important social and environmental impact, and should be studied within the framework of integrated water resource management and sustainable development. Dams and Reservoirs, Societies and Environment in the 21st Century presents the latest research on the role played by dams and reservoirs in 21st century societies, in developed, emergent and developing countries. It analyses the viability of dams and suggests alternative solutions from a holistic perspective, considering the technical, economic, social and environmental aspects. Other issues covered include the social acceptability of dams, public involvement and dam awareness. The book covers subjects ranging from dam engineering, through the benefits and drawbacks of dams, to their social and environmental impact, and contains numerous case studies of the constructive contributions that reservoirs have made to water development and management. The book is a valuable resource for professional and dam engineers, water managers, governmental organizations and commercial enterprises responsible for dam development and management.

Download or read book Grouting Theory and Practice written by E. Nonveiller and published by Elsevier. This book was released on 2013-06-11 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Engineering Geology for Society and Territory Volume 5 written by Giorgio Lollino and published by Springer. This book was released on 2014-08-25 with total page 1304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is one out of 8 IAEG XII Congress volumes, and deals with the theme of urban geology. Along with a rapidly growing world population, the wave of urban growth continues, causing cities to swell and new metropolitan centers to emerge. These global trends also open new ventures for underground city development. Engineering geology plays a major role in facing the increasing issues of the urban environment, such as: finding aggregates for construction works; providing adequate water supply and waste management; solving building problems associated to geological and geomorphological conditions; evaluating host rock conditions for underground constructions; preventing or mitigating geological and seismic hazards. Furthermore, this book illustrates recent advancements in sustainable land use planning, which includes conservation, protection, reclamation and landscape impact of open pit mining and alternative power generation. The Engineering Geology for Society and Territory volumes of the IAEG XII Congress held in Torino from September 15-19, 2014, analyze the dynamic role of engineering geology in our changing world and build on the four main themes of the congress: environment, processes, issues and approaches. The congress topics and subject areas of the 8 IAEG XII Congress volumes are: 1. Climate Change and Engineering Geology 2. Landslide Processes River Basins 3. Reservoir Sedimentation and Water Resources 4. Marine and Coastal Processes Urban Geology 5. Sustainable Planning and Landscape Exploitation 6. Applied Geology for Major Engineering Projects 7. Education, Professional Ethics and Public Recognition of Engineering Geology 8. Preservation of Cultural Heritage
