Book Description
With this fact established, a hypothesis of the action of such a culvert under an actual earth embankment was devised and each loaded pipe was analyzed to determine its horizontal and vertical deflections, its bending moments, and its tangential thrusts. The hypothesis assumes a uniformly distributed vertical load and vertical reaction, and a passive pressure against the sides of the pipe distributed approximately parabolically over the middle 100 degrees of the pipe sides. The passive pressure is postulated to be proportional in magnitude to the lateral movement of the sides of the pipe. Extensive full-scale experiments on flexible culverts ranging from 36 to 60 in. in diameter were conducted. The pipes were loaded by embankments of several kinds of soil 15 and 16 ft. high, without traffic loads, and the loads, deflections, radial pressures, settlements and other pertinent data were observed. These experiments amply verify the design formula developed from the load hypothesis.

Book Description
FLEXIBLE PIPELINES AND POWER CABLES Pipelines are an important part of the world’s energy infrastructure, and, without them, oil and gas, the most commonly used sources for energy today, would not be available to much of the world’s countries. New theories and designs are constantly being researched and developed by scientists and engineers, to continue improving this technology and making it safer and more economical. The technology, processes, materials, and theories surrounding pipeline construction, application, and troubleshooting are constantly changing, and this groundbreaking series, “Advances in Pipes and Pipelines,” has been created to meet the needs of engineers and scientists to keep them up to date and informed of all of these advances. This latest volume in the series focuses on flexible pipelines and power cables, offering the engineer the most thorough coverage of the state of the art available. The authors of this work have written numerous books and papers on these subjects and are some of the most influential authors on flexible pipes in the world, contributing much of the literature on this subject to the industry. This new volume is a presentation of some of the most cutting-edge technological advances in technical publishing. This is the most comprehensive and in-depth series on pipelines, covering not just the various materials and their aspects that make them different, but every process that goes into their installation, operation, and design. This is the future of pipelines, and it is an important breakthrough. A must-have for the veteran engineer and student alike, this volume is an important new advancement in the energy industry, a strong link in the chain of the world’s energy production.

Book Description
Recent changes in the codes for building pipelines has led to a boom in the production of new materials that can be used in flexible pipes. With the use of polymers, steel, and other new materials and variations on existing materials, the construction and, therefore, the installation and operation of flexible pipes is changing and being improved upon all over the world. The authors of this work have written numerous books and papers on these subjects and are some of the most influential authors on flexible pipes in the world, contributing much of the literature on this subject to the industry. This new volume is a presentation of some of the most cutting-edge technological advances in technical publishing. This is the most comprehensive and in-depth book on this subject, covering not just the various materials and their aspects that make them different, but every process that goes into their installation, operation, and design. The thirty-six chapters, divided up into four different parts, have had not just the authors of this text but literally dozens of other engineers who are some of the world’s leading scientists in this area contribute to the work. This is the future of pipelines, and it is an important breakthrough. A must-have for the veteran engineer and student alike, this volume is an important new advancement in the energy industry, a strong link in the chain of the world’s energy production.

Book Description
Technology now affects almost every aspect of Water Supply Management, Operation, Planning and Design; the speed of development means that assessing what is "new" is sometimes difficult. Old ideas can now be applied because of new technology; technology is now revealing problems that were unnoticed 10 years ago. Some emerging technologies promise much but are still underdeveloped for use in real world conditions, while we should always remember that "new" technology depends upon the state of development in respective countries, a point which is particularly relevant to the NATO Advanced Study Institute, for which this book has been produced. Thus our objective in producing the book has been to highlight, in a wide range of technical areas, where and how technology is being applied, what is "new" and what the limitations of these technologies are in the real world. We have also tried to provide an European and American perspective where possible to illustrate how problems are tackled in different cultural environments. It is probably true that "technology" is also somewhat dependent upon the political, economic and organisational climate in different countries and we have included a chapter covering these aspects.
