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.

Consideration of the assumptions made in Terzaghi's theory of consolidation indicates that a main source of error is in the assumed rheological behaviour of the soil skeleton. Based on the Terzaghi-Taylor concept of secondary consolidation a more natural non-linear rheological model is proposed and an approximate finite difference solution obtained using a digital computer. This solution, obtained in dimensionless form, emphasizcs the continuous nature of the consolidation process and indicates errors involved in arbitrary divisions into primary and secondary stages. The amount of secondary compression is shown to be strongly dependent on the thickness of the sample and on the pressure increment ratio, but the solution provides a simple method of accounting for this in the extrapolation of settlementtime data obtained in laboratory tests to the field scale.

This book sheds light on how the modern 3-bladed wind turbine came into being, and who, how and what in the proceeding period caused the success. It looks back over three decades to find the roots of this exciting development, a long cavalcade of developers, inventors, and manufacturers including the Danish authors who themselves were part of the breakthrough. Written for non-specialists, the book covers minimal science, emphasizing the story of how wind power became a worldwide 30-billion-euro business employing nearly one million people.

Author: Luis Gonzalez de Vallejo and Mercedes Ferrer | Size: 50 MB | Format:PDF | Quality:Unspecified | Publisher: CRC Press | Year: 2011 | pages: 700 pages | ISBN: 978-0415413527
This beautifully illustrated text book has everything an engineering geologist and those with a wide interest in civil engineering could wish for. The content of Geological Engineering is a suitable reminder of the huge range of disciplines and engineering problems that are expected to be tackled during the career of experienced international consultants, by international civil engineering design offices, by earth science researchers, and by graduate students starting out in this fascinating but challenging major branch of science and engineering. All the back-ground needed for those engaged in foundations, slopes, tunnels, dams and reservoirs and earth structures can be found here.
The applications of block theory in planning and design of surface and underground excavations and in support of foundations are illustrated in a large number of examples. Computer programs (available from the authors*) can be used by the reader to duplicate these illustrations.
