2016年12月(yue)31日，深(shen)厚覆蓋層上世界在(zai)建(jian)最高壩工程——長河壩水(shui)電(dian)站首臺(tai)4號機組順(shun)利并(bing)網發電(dian)。至(zhi)此(ci)，四川水(shui)電(dian)裝機突破7000萬(wan)千(qian)瓦大(da)關，達7030萬(wan)千(qian)瓦，占全(quan)省發電(dian)裝機80%，讓(rang)四川全(quan)國清潔能源基地的(de)地位進一步(bu)凸顯。
長河壩水(shui)(shui)(shui)電(dian)(dian)(dian)站(zhan)由中國電(dian)(dian)(dian)建(jian)集團所(suo)屬(shu)成都院勘測(ce)設計，水(shui)(shui)(shui)電(dian)(dian)(dian)五局、七局負責(ze)大(da)(da)壩、泄洪洞施(shi)工(gong)(gong)(gong)(gong)及機組安裝，水(shui)(shui)(shui)電(dian)(dian)(dian)十四局承擔廠房施(shi)工(gong)(gong)(gong)(gong)。開工(gong)(gong)(gong)(gong)建(jian)設以來，工(gong)(gong)(gong)(gong)程(cheng)(cheng)遭遇(yu)了汶川特大(da)(da)地震(zhen)、響(xiang)水(shui)(shui)(shui)溝泥石流災害(hai)、蘆山地震(zhen)、康定(ding)地震(zhen)等自然災害(hai)影響(xiang)。參建(jian)企業，根據工(gong)(gong)(gong)(gong)程(cheng)(cheng)實際情況精細設計，科學施(shi)工(gong)(gong)(gong)(gong)，開展大(da)(da)量(liang)科研攻關(guan)，充(chong)分考慮類似工(gong)(gong)(gong)(gong)程(cheng)(cheng)經驗及新形勢(shi)下水(shui)(shui)(shui)電(dian)(dian)(dian)和諧、科學開發(fa)的需(xu)要，力求方(fang)(fang)案(an)安全可靠、施(shi)工(gong)(gong)(gong)(gong)可行、經濟(ji)合理、工(gong)(gong)(gong)(gong)期最優，為(wei)工(gong)(gong)(gong)(gong)程(cheng)(cheng)順利(li)推(tui)進(jin)、按時投(tou)產、提(ti)前(qian)發(fa)揮綜合效應(ying)奠定(ding)了堅實基礎，顯示出集團在巨、大(da)(da)型水(shui)(shui)(shui)電(dian)(dian)(dian)工(gong)(gong)(gong)(gong)程(cheng)(cheng)設計施(shi)工(gong)(gong)(gong)(gong)方(fang)(fang)面(mian)具有雄厚的技(ji)術實力。
長河壩水電(dian)(dian)站(zhan)位于四川省甘孜(zi)藏族自治州康定縣境(jing)內(nei)，為大渡(du)河干流(liu)“3庫22級”開發的(de)第10級電(dian)(dian)站(zhan)，攔河大壩最大壩高(gao)(gao)240米，壩基(ji)覆蓋層厚(hou)度50余米，總裝機容量(liang)(liang)260萬千(qian)瓦，年(nian)發電(dian)(dian)量(liang)(liang)107.9億(yi)千(qian)瓦時。工程具有超高(gao)(gao)邊坡、超高(gao)(gao)土(tu)石壩、高(gao)(gao)地應力洞(dong)室群、強震區高(gao)(gao)進水塔、高(gao)(gao)流(liu)速(su)大功率泄洪、高(gao)(gao)強度大型(xing)復雜洞(dong)室交通等特點，工程設計與建(jian)設頗具難度和挑戰。
