人类筑坝历史相当久远,但以近代科学方法筑坝,不过百年左右。而大量建造大库容的高坝,始于本世纪20～30年代。第二次世界大战后至今,各国为了充分利用水利水电资源,大库容高坝不断涌现。到了60年代,已经达到相当可观的数目,根据国际大坝委员会的《世界大坝统计》,自1928年国际大坝委员会建立至60年代末(1970年),有大坝8000座,而当时在建的约1000座,大坝委员会建立之前已有1000座左右,总数约1万余座(均指坝高大于15m者)。也许是大坝委员会统计不精,单 The history of human dams has been quite long ago, but it has been damped by modern scientific methods, but it has been around for a hundred years. The large dam building a large reservoir, began in the 20 to 30 years of this century. Since the Second World War so far, in order to make full use of water conservancy and hydropower resources in various countries, large reservoirs of high dam continue to emerge. By the 1960s considerable numbers had been reached. According to the World Commission on Dams statistics, from the establishment of the International Commission on Dams in 1928 to the end of the 1960s (1970), there were 8,000 dams, About 1,000 have been built. About 1,000 dams have been established before the establishment of the Dams Committee and the total number of them is about 10,000 (both are more than 15m in height). Perhaps the dam committee statistics are not good, single
