2016年12月31日(ri)，深厚覆蓋層上世界在建最高壩工程——長河(he)壩水電(dian)(dian)站首臺4號機(ji)組順(shun)利并網發電(dian)(dian)。至此，四(si)川(chuan)(chuan)水電(dian)(dian)裝機(ji)突(tu)破7000萬千(qian)(qian)瓦大(da)關(guan)，達7030萬千(qian)(qian)瓦，占全省(sheng)發電(dian)(dian)裝機(ji)80%，讓四(si)川(chuan)(chuan)全國(guo)清(qing)潔能源基地(di)的地(di)位進一步(bu)凸顯。
長河壩水電(dian)(dian)站由中國電(dian)(dian)建(jian)集團所(suo)屬成都院勘測設(she)(she)(she)計(ji)，水電(dian)(dian)五局、七局負責大(da)(da)壩、泄洪洞施(shi)工(gong)(gong)(gong)及機組安(an)裝，水電(dian)(dian)十四局承擔廠房(fang)施(shi)工(gong)(gong)(gong)。開(kai)(kai)工(gong)(gong)(gong)建(jian)設(she)(she)(she)以來，工(gong)(gong)(gong)程(cheng)遭遇了(le)汶川特大(da)(da)地(di)震、響水溝泥石流災害、蘆山地(di)震、康定地(di)震等(deng)自(zi)然災害影響。參建(jian)企業，根據工(gong)(gong)(gong)程(cheng)實(shi)際情(qing)況精細(xi)設(she)(she)(she)計(ji)，科學(xue)施(shi)工(gong)(gong)(gong)，開(kai)(kai)展大(da)(da)量(liang)科研(yan)攻關，充(chong)分考慮類似工(gong)(gong)(gong)程(cheng)經(jing)驗及新形勢(shi)下水電(dian)(dian)和諧、科學(xue)開(kai)(kai)發的(de)需要，力求方(fang)案安(an)全可(ke)靠、施(shi)工(gong)(gong)(gong)可(ke)行、經(jing)濟(ji)合理、工(gong)(gong)(gong)期(qi)最優，為工(gong)(gong)(gong)程(cheng)順利推(tui)進、按(an)時投(tou)產、提(ti)前發揮綜合效(xiao)應奠定了(le)堅實(shi)基礎(chu)，顯示出集團在巨、大(da)(da)型水電(dian)(dian)工(gong)(gong)(gong)程(cheng)設(she)(she)(she)計(ji)施(shi)工(gong)(gong)(gong)方(fang)面具有雄厚的(de)技術(shu)實(shi)力。
長河壩(ba)水電站位于四川省(sheng)甘(gan)孜藏族自治(zhi)州康定縣境內，為大渡河干流“3庫22級”開發(fa)(fa)的第(di)10級電站，攔(lan)河大壩(ba)最大壩(ba)高(gao)240米(mi)，壩(ba)基覆蓋層(ceng)厚度(du)50余米(mi)，總裝機容量260萬千瓦，年發(fa)(fa)電量107.9億千瓦時。工程具有超高(gao)邊坡、超高(gao)土石壩(ba)、高(gao)地應(ying)力(li)洞(dong)室群(qun)、強(qiang)(qiang)震區高(gao)進水塔、高(gao)流速大功(gong)率泄洪、高(gao)強(qiang)(qiang)度(du)大型復雜洞(dong)室交通等特點，工程設計與建設頗具難度(du)和(he)挑戰。
