一九八○年10月在印度新德里举行的第十三届国际大坝会议上,共讨论了四个专题,(大流量的底孔和溢洪道)是其主要专题之一。对于这个专题,30个国家提出共62篇报告,我国提出了三篇。这些国家分布于世界各大洲,虽然天然条件各异,但均有建造高坝的经验。报告之外,还有奥地利、美国、罗得西亚、日本、瑞士、加拿大、意大利、瑞典等八个国家的大坝委员会提出总评。这届大坝会议是有史以来首次专门单独讨论新型大流量的底孔和溢洪道这一专题的,参加讨论的作者如此众多、踊跃,足见这一专题在高坝建设中的重要性。
During the Thirteenth International Conference on Dams held in New Delhi, India, in October 1980, a total of four topics were discussed, one of its main topics being the large flow of bottom holes and spillways. For this topic, a total of 62 reports were submitted by 30 countries and three were submitted by our country. These countries are located in all continents of the world, and although they have different natural conditions, they all have experience in building high dams. In addition to the report, there are general comments from the dams committees of eight countries including Austria, the United States, Rhodesia, Japan, Switzerland, Canada, Italy and Sweden. This dams meeting was the first time in history ever dedicated solely to discussing the new type of large-flow bottom hole and spillway. The large number of authors participating in the discussion enthusiastically reflected the importance of this topic in the construction of high dams.
