目前国内外混凝土坝的施工技术仍然沿袭着1936年美国胡佛坝所采用的柱状浇筑法。尽管这种传统的施工方法已日臻完善,但仍存在着浇筑工期长、造价高等弊病。为探索混凝土坝快速、优质、低成本的新施工方法,意、苏、美、英、日等国从六十年代开始进行了大量试验研究工作,取得了一些成果。借鉴外国的先进经验,结合我国混凝土坝现实的施工水平,我局于1978年开展了薄层浇筑法的试验研究。
At present, the construction technology of concrete dams at home and abroad still follows the column pouring method adopted by the U.S. Hoover Dam in 1936. Despite this traditional method of construction has been improving, but there is still a long pouring period, the cost of higher ills. In order to explore a new construction method of rapid, high quality and low cost for concrete dams, Italy, the United States, Britain, Japan and other countries started a large number of experimental studies from the 1960s and achieved some results. Draw lessons from foreign advanced experience, combined with the actual construction level of concrete dam in our country, our bureau conducted a pilot study of the thin-layer pouring method in 1978.
