2016年12月(yue)31日，深厚覆蓋層上(shang)世界在建最高(gao)壩工程——長河壩水(shui)電(dian)站首臺4號機組順利并網發電(dian)。至此，四(si)川(chuan)水(shui)電(dian)裝機突破7000萬(wan)千(qian)(qian)瓦(wa)大關，達(da)7030萬(wan)千(qian)(qian)瓦(wa)，占(zhan)全省(sheng)發電(dian)裝機80%，讓四(si)川(chuan)全國(guo)清潔(jie)能源基(ji)地的地位進(jin)一步(bu)凸顯。
長河(he)壩(ba)水(shui)電(dian)站由中國電(dian)建集(ji)團所屬(shu)成都院勘測設計(ji)，水(shui)電(dian)五局(ju)(ju)、七局(ju)(ju)負責大(da)壩(ba)、泄洪(hong)洞(dong)施(shi)工(gong)(gong)(gong)及(ji)機組安(an)裝，水(shui)電(dian)十四局(ju)(ju)承擔廠房施(shi)工(gong)(gong)(gong)。開工(gong)(gong)(gong)建設以(yi)來，工(gong)(gong)(gong)程遭(zao)遇了汶川特(te)大(da)地(di)震(zhen)(zhen)(zhen)、響水(shui)溝(gou)泥石流災害(hai)、蘆山地(di)震(zhen)(zhen)(zhen)、康定(ding)地(di)震(zhen)(zhen)(zhen)等自然災害(hai)影響。參建企業，根據工(gong)(gong)(gong)程實際情況(kuang)精(jing)細設計(ji)，科學(xue)施(shi)工(gong)(gong)(gong)，開展(zhan)大(da)量科研攻關，充分考(kao)慮類似工(gong)(gong)(gong)程經驗及(ji)新(xin)形勢(shi)下水(shui)電(dian)和(he)諧、科學(xue)開發(fa)的(de)需要，力求方案安(an)全可靠、施(shi)工(gong)(gong)(gong)可行、經濟合理、工(gong)(gong)(gong)期最優(you)，為工(gong)(gong)(gong)程順(shun)利推進、按時投(tou)產、提前發(fa)揮綜合效應奠定(ding)了堅實基礎(chu)，顯示(shi)出集(ji)團在巨、大(da)型水(shui)電(dian)工(gong)(gong)(gong)程設計(ji)施(shi)工(gong)(gong)(gong)方面具有雄厚的(de)技術(shu)實力。
長河(he)(he)壩(ba)(ba)水電站位(wei)于四川省甘孜藏族自(zi)治(zhi)州康定縣境內，為(wei)大(da)(da)渡河(he)(he)干(gan)流“3庫22級”開發的第10級電站，攔河(he)(he)大(da)(da)壩(ba)(ba)最大(da)(da)壩(ba)(ba)高240米(mi)(mi)，壩(ba)(ba)基(ji)覆蓋層厚度50余米(mi)(mi)，總(zong)裝(zhuang)機(ji)容量(liang)(liang)260萬(wan)千瓦，年發電量(liang)(liang)107.9億千瓦時。工(gong)程(cheng)具有超高邊(bian)坡、超高土(tu)石(shi)壩(ba)(ba)、高地應力洞室群(qun)、強震區(qu)高進水塔、高流速(su)大(da)(da)功率泄洪、高強度大(da)(da)型復雜洞室交通等特點，工(gong)程(cheng)設計與建設頗(po)具難(nan)度和挑戰。
