摘　　要：贫胶粗粒料筑坝技术结合了面板堆石坝和碾压混凝土坝的特点,具有坝基适应性广、施工快捷、安全环保、投资经济的优越性,是一种极富潜力的绿色环保筑坝新技术。福建省水利水电勘测设计研究院会同施工等单位,依托洪口水电站上游主围堰开展科研攻关,在有效施工时间仅为50d的情况下围堰总填筑量达到3.2万m3,最大日上升高度为1.2m,于2006年4月建成高35.5m的贫胶粗粒料围堰。围堰建成后就经历了近50年一遇超标洪水的过水考验,首次实现该技术在30m以上中坝高度的成功应用。The technology of lean cemented aggregate dam construction combines the feature of concrete facing rockfill dam and RCC dam, which has the advantages of wide-ranging suitability of embankment, fast-speed construction, safe and environment-friendly and cost-effective, and is green dam construction technology with great potential. Scientific research of upper stream cofferdam construction was carried out by the Fujian Institute of Water and Hydropower Reconnaissance and Design together with constructors of Hongkou Hydropower Station. Total concrete pouring of cofferdam in 50 days reached to 32,000 cubic meters and maximum daily rise was 1.2 m. In April 2006, lean cemented aggregate cofferdam of 35.5m high was completed, which experienced the test of once in 50 years flood. This is the first successful application of the technology in construction of dam above 30m.
