9月28日，由葛洲壩集團西北分公司承建的我國最高礫石土心墻堆石壩——瀑布溝水電站大壩成功下閘蓄水，比計劃工期提前一個半月。業主國電集團大渡河公司對葛洲壩集團為工程建設作出的貢獻表示感謝。
當日上午10時整，位于大壩右岸1號導流洞的2扇閘門在啟閉機驅動下，穩穩落入1號導流底孔閘門槽。上游蓄水按設計要求穩步升高，為年內雙臺機組投產發電奠定了堅實基礎。
瀑布溝水電站位(wei)于四川省雅安市漢源縣(xian)，是(shi)大(da)渡河流域水能(neng)資源滾(gun)動(dong)開發的骨干工(gong)(gong)(gong)程(cheng)(cheng)。電站設計總裝機容量330萬千瓦，多年平(ping)均發電量145.5億千瓦時。最大(da)壩(ba)(ba)(ba)(ba)高186米(mi)，壩(ba)(ba)(ba)(ba)頂(ding)高程(cheng)(cheng)856米(mi)，壩(ba)(ba)(ba)(ba)體(ti)填(tian)(tian)筑(zhu)量約為2300萬立方(fang)米(mi)，其中礫(li)(li)石(shi)土(tu)填(tian)(tian)筑(zhu)283萬立方(fang)米(mi)，為國內(nei)最高礫(li)(li)石(shi)土(tu)心墻堆石(shi)壩(ba)(ba)(ba)(ba)。該工(gong)(gong)(gong)程(cheng)(cheng)地(di)(di)質條件復(fu)雜，技術難(nan)度(du)高，施(shi)工(gong)(gong)(gong)難(nan)度(du)大(da)。葛(ge)洲(zhou)(zhou)壩(ba)(ba)(ba)(ba)人經(jing)受洪水、冰災(zai)、地(di)(di)震、工(gong)(gong)(gong)程(cheng)(cheng)地(di)(di)質結構復(fu)雜等考驗，精心組織(zhi)，優化工(gong)(gong)(gong)藝，科學施(shi)工(gong)(gong)(gong)，順利完成了(le)施(shi)工(gong)(gong)(gong)任務，為葛(ge)洲(zhou)(zhou)壩(ba)(ba)(ba)(ba)集(ji)團(tuan)在(zai)大(da)渡河流域樹立了(le)豐(feng)碑，也為葛(ge)洲(zhou)(zhou)壩(ba)(ba)(ba)(ba)集(ji)團(tuan)在(zai)礫(li)(li)石(shi)土(tu)高壩(ba)(ba)(ba)(ba)施(shi)工(gong)(gong)(gong)方(fang)面(mian)積累了(le)寶(bao)貴經(jing)驗。
