Design Standards Embankment Dams No. 13, Chapter 20: Geomembranes. Volume 1 of 2

摘要

Geomembranes have been used in a number of dams in Europe, but, in spite of the pioneering work done by the Bureau of Reclamation, they have not yet been significantly used in dams in the United States. On the other hand, the use of geomembranes and other geosynthetics in liing systems for waste containment facilities is far more advanced in the U.S.A. than in any other country. The document draws from European experience in dam design and American experience on geomembrane properties. Also, many of the concepts and methods presented in the document were originally developed for the design of geomembrane-lined waste containment facilities, and have been adapted to the design and construction of dams. These include, for example: leakage control systems, stability analyses for lining systems on slopes, and geosynthetic construction quality assurance. Although the document is essentially devoted to geomembranes, other geosynthetics, such as geotextiles, geonets, and geogrids, are discussed in those systems or applications where they are closely associated with geomembranes.
