近期，中國(guo)國(guo)電(dian)集團公司(si)所屬的(de)瀑布(bu)溝水電(dian)站(zhan)工程作為唯一的(de)水利水電(dian)工程，獲得(de)第十(shi)四屆中國(guo)土木(mu)工程詹天(tian)佑獎。
瀑布溝水(shui)電(dian)站工程獲(huo)得中(zhong)國(guo)土木工程詹天佑獎(jiang)，展(zhan)現了工程在設計、建(jian)設、管(guan)理等技術方(fang)面應有顯著的創造(zao)性和較高的科技含量，反映了當今我國(guo)同類工程技術質量的最高水(shui)平。
瀑(pu)布溝水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)站(zhan)是(shi)國(guo)家(jia)“十五”重點建設項(xiang)目，也是(shi)國(guo)家(jia)西(xi)部(bu)大(da)(da)開(kai)發的標志性工程之一。電(dian)(dian)(dian)(dian)站(zhan)采(cai)用堤壩式(shi)(shi)開(kai)發，是(shi)一座以發電(dian)(dian)(dian)(dian)為主，兼有防(fang)洪、攔沙等綜合(he)利(li)用效益的大(da)(da)型水(shui)(shui)(shui)利(li)水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)樞紐工程。電(dian)(dian)(dian)(dian)站(zhan)總裝機(ji)(ji)容量3600兆瓦，安裝6臺單機(ji)(ji)容量600兆瓦的混流(liu)式(shi)(shi)水(shui)(shui)(shui)輪發電(dian)(dian)(dian)(dian)機(ji)(ji)組，多(duo)年平均發電(dian)(dian)(dian)(dian)量147.9億(yi)(yi)千瓦時，是(shi)四川省(sheng)境內骨干調(diao)峰(feng)調(diao)頻電(dian)(dian)(dian)(dian)站(zhan)。電(dian)(dian)(dian)(dian)站(zhan)水(shui)(shui)(shui)庫總庫容53.37億(yi)(yi)方(fang)，是(shi)大(da)(da)渡河中游控制性水(shui)(shui)(shui)庫，具有年調(diao)節能力。
電站樞紐工程由礫石(shi)土(tu)(tu)心墻(qiang)(qiang)(qiang)堆石(shi)壩、溢(yi)洪(hong)(hong)道(dao)、泄洪(hong)(hong)洞、放(fang)空(kong)洞、引水(shui)(shui)(shui)發電系(xi)統(tong)等(deng)組成。大(da)(da)(da)壩是(shi)世界(jie)深厚覆蓋層上修建高心墻(qiang)(qiang)(qiang)土(tu)(tu)石(shi)壩的(de)經典之作，攻(gong)(gong)克了寬(kuan)級(ji)配(pei)礫石(shi)土(tu)(tu)作防滲體的(de)世界(jie)難題，首(shou)次實現(xian)寬(kuan)級(ji)配(pei)礫石(shi)土(tu)(tu)用作大(da)(da)(da)壩心墻(qiang)(qiang)(qiang)防滲料(liao)；攻(gong)(gong)克深厚覆蓋層上建高心墻(qiang)(qiang)(qiang)堆石(shi)壩重大(da)(da)(da)難題，創新壩基防滲結構，將(jiang)防滲墻(qiang)(qiang)(qiang)與大(da)(da)(da)壩心墻(qiang)(qiang)(qiang)連接，與基巖防滲帷幕共同(tong)形成完整的(de)防滲體系(xi)；采(cai)取分散泄洪(hong)(hong)、消能(neng)方(fang)式，特別是(shi)溢(yi)洪(hong)(hong)道(dao)出口采(cai)用鷹嘴式挑(tiao)流(liu)鼻坎，解決了岸邊(bian)溢(yi)洪(hong)(hong)道(dao)布置及大(da)(da)(da)流(liu)量高速(su)水(shui)(shui)(shui)流(liu)泄洪(hong)(hong)、消能(neng)和霧化等(deng)難題。工程建設節(jie)能(neng)、節(jie)地(di)、節(jie)水(shui)(shui)(shui)、節(jie)材效(xiao)果顯著，施工技術(shu)、進(jin)度、質(zhi)量總體水(shui)(shui)(shui)平(ping)國(guo)內一(yi)流(liu)，2011年被國(guo)際大(da)(da)(da)壩協會授予“堆石(shi)壩國(guo)際里程碑工程”。
