3月13日(ri)，白(bai)鶴灘水電站順(shun)利(li)通(tong)過(guo)蓄(xu)水前樞紐工程安(an)全鑒定，標志著向“七一”蓄(xu)水發電目標又邁出堅實(shi)一步。

蓄(xu)水(shui)前安全(quan)鑒定是(shi)對白鶴(he)灘水(shui)電站樞紐工程(cheng)(cheng)建設全(quan)過(guo)程(cheng)(cheng)的(de)全(quan)面(mian)檢查，是(shi)對工程(cheng)(cheng)蓄(xu)水(shui)條件的(de)總體(ti)評價，是(shi)蓄(xu)水(shui)驗(yan)收的(de)重(zhong)要前置程(cheng)(cheng)序。

為(wei)做好此次(ci)安(an)全鑒(jian)定(ding)(ding)，中國水(shui)(shui)利水(shui)(shui)電建(jian)(jian)(jian)設工(gong)(gong)(gong)程(cheng)咨詢有限公(gong)司組(zu)(zu)織了涵蓋水(shui)(shui)工(gong)(gong)(gong)、防洪(hong)、地質(zhi)、施(shi)工(gong)(gong)(gong)、金結、監測等(deng)6大專(zhuan)業，由26名專(zhuan)家(jia)(jia)組(zu)(zu)成的(de)專(zhuan)家(jia)(jia)組(zu)(zu)。從(cong)3月(yue)2日(ri)專(zhuan)家(jia)(jia)組(zu)(zu)啟動工(gong)(gong)(gong)作(zuo)以(yi)來，通過資料(liao)閱研(yan)和(he)(he)現(xian)場查勘，并與工(gong)(gong)(gong)程(cheng)參建(jian)(jian)(jian)各方(fang)充分(fen)討論交流(liu)(liu)，經(jing)過歷時12天的(de)持(chi)續工(gong)(gong)(gong)作(zuo)，形成了蓄(xu)(xu)水(shui)(shui)前安(an)全鑒(jian)定(ding)(ding)結論意見(jian)：“白鶴灘(tan)水(shui)(shui)電站樞紐工(gong)(gong)(gong)程(cheng)建(jian)(jian)(jian)設形象面貌和(he)(he)計劃安(an)排(pai)可(ke)滿(man)足2021年4月(yue)導(dao)流(liu)(liu)底(di)孔(kong)(kong)(kong)(kong)下閘、水(shui)(shui)庫(ku)蓄(xu)(xu)水(shui)(shui)以(yi)及2021年汛(xun)期(qi)防洪(hong)度汛(xun)形象面貌要求(qiu)(qiu)。白鶴灘(tan)水(shui)(shui)電站樞紐工(gong)(gong)(gong)程(cheng)建(jian)(jian)(jian)筑物設計符合(he)規范規定(ding)(ding)；已(yi)完(wan)土建(jian)(jian)(jian)工(gong)(gong)(gong)程(cheng)、金屬結構工(gong)(gong)(gong)程(cheng)、安(an)全監測工(gong)(gong)(gong)程(cheng)的(de)施(shi)工(gong)(gong)(gong)及制造和(he)(he)安(an)裝(zhuang)質(zhi)量總體滿(man)足設計、國家(jia)(jia)和(he)(he)行業有關技(ji)術標準及工(gong)(gong)(gong)程(cheng)合(he)同文(wen)件的(de)要求(qiu)(qiu)。設計復核及已(yi)有監測成果表明，大壩等(deng)樞紐建(jian)(jian)(jian)筑物工(gong)(gong)(gong)作(zuo)性態正常，工(gong)(gong)(gong)程(cheng)區邊坡和(he)(he)近壩庫(ku)岸整(zheng)體穩定(ding)(ding)，導(dao)流(liu)(liu)底(di)孔(kong)(kong)(kong)(kong)過流(liu)(liu)正常。導(dao)流(liu)(liu)底(di)孔(kong)(kong)(kong)(kong)下閘方(fang)案、水(shui)(shui)庫(ku)初期(qi)蓄(xu)(xu)水(shui)(shui)方(fang)案、工(gong)(gong)(gong)程(cheng)防洪(hong)度汛(xun)方(fang)案和(he)(he)措(cuo)施(shi)總體可(ke)行，導(dao)流(liu)(liu)底(di)孔(kong)(kong)(kong)(kong)下閘準備工(gong)(gong)(gong)作(zuo)基(ji)本就緒。據(ju)此，白鶴灘(tan)水(shui)(shui)電站樞紐工(gong)(gong)(gong)程(cheng)具備導(dao)流(liu)(liu)底(di)孔(kong)(kong)(kong)(kong)下閘蓄(xu)(xu)水(shui)(shui)的(de)條件。”

此(ci)次安全(quan)(quan)鑒定過程(cheng)中，3月11日(ri)至16日(ri)還同步開展(zhan)了(le)工程(cheng)輸水(shui)發電系統專項安全(quan)(quan)鑒定現場(chang)(chang)檢(jian)查。現場(chang)(chang)檢(jian)查意(yi)見(jian)認為，“白鶴灘(tan)水(shui)電站輸水(shui)發電系統工程(cheng)已(yi)基本具(ju)備尾水(shui)系統充(chong)水(shui)條件，以及2021年5月實施首批(pi)機(ji)組引水(shui)系統充(chong)水(shui)的條件，機(ji)組段充(chong)水(shui)可根據機(ji)組安裝(zhuang)調試要(yao)求適時安排。”標志(zhi)著白鶴灘(tan)工程(cheng)已(yi)具(ju)備開展(zhan)機(ji)組啟(qi)動(dong)驗收的條件。

后(hou)續，工(gong)程蓄水驗收(shou)委(wei)員會將在此(ci)次安全鑒(jian)定(ding)和同期開展的(de)專項質(zhi)量監(jian)督結論意見的(de)基礎上，組織工(gong)程蓄水驗收(shou)工(gong)作。白(bai)鶴灘水電站已做好蓄水發(fa)電準備，進入“七一”發(fa)電倒(dao)計時。
