2010 ICOLD Bulletin on geomembrane sealing systems for dams

摘要

The 2010 International Commission on Large Dams (ICOLD) Bulletin on "Geomembrane Sealing Systems for Dams" (ICOLD Bulletin No. 135) supersedes and greatly expands upon two earlier versions published in 1981 (Bulletin 38) and 1991 (Bulletin 78). The 265 dams incorporating geomembranes cited in this new Bulletin include 183 fill, 47 concrete, 34 roller compacted concrete, and 1 hybrid. Of the total, 118 (45%) are in Europe, 48 (18%) are in the United States, 47 (18%) are in China, and the remaining 52 (19%) are scattered in other countries and locations. Since most of the experience gained to date is in Europe, the European Working Group on Geomembranes prepared the Bulletin with the assistance of the primary author of this article. This article attempts to summarize the 242 pages of the English-language portion of the Bulletin and is subdivided according to the same structure. The Bulletin concludes with a brief section on quality control and another on guidance for technical content of contracts. It is published in English and French.
