随着水电事业的发展,以及现代施工机械和施工技术的不断改进和完善,促进了高土石坝的应用和发展。目前国外兴建的百米以上高坝中土石坝已占62％以上,而我国仅占18％。在各种类型的土石坝中,混凝土面板碾压堆石坝[CFRD]——土石坝的一种新坝型,以其独特的优越性正日益引起人们的注意。当前国外已建和在建的CFRD已近百座,其中百米以上就有20多座。已建成的最高CFRD是巴西的阿利亚坝(Fozdo Areia),正在规划设计的哥伦比亚的拉米尔坝(La Mie)坝高达200米。从这些工程设计、施工和应用实践表明CFRD具
With the development of hydropower, as well as the continuous improvement and improvement of modern construction machinery and construction technology, the application and development of high earth-rock dam are promoted. At present, more than one hundred meters of high dam earth dam accounts for more than 62%, while China only accounts for 18%. Among various types of earth-rockfill dams, a new type of concrete faced-rockfill dam [CFRD] - earth-rockfill dam is attracting more and more attentions due to its unique superiority. At present, there are nearly 100 CFRDs already under construction and under construction in the country, of which more than 20 are above 100 meters. The highest completed CFRD is Fozdo Areia, Brazil, and is planned for up to 200 meters of the La Mie dam in Colombia. From these engineering design, construction and application practices show that CFRD has
