2016年12月31日，深(shen)厚(hou)覆蓋(gai)層上世界在建最高壩工(gong)程(cheng)——長河壩水電(dian)站首(shou)臺4號(hao)機(ji)(ji)(ji)組(zu)順利并網發電(dian)。至此，四川水電(dian)裝機(ji)(ji)(ji)突破7000萬千瓦大關，達7030萬千瓦，占全省(sheng)發電(dian)裝機(ji)(ji)(ji)80%，讓四川全國清潔能源基地的地位進一步(bu)凸(tu)顯。
長河壩(ba)水電(dian)(dian)(dian)站由中國電(dian)(dian)(dian)建集團所屬成都院(yuan)勘測設(she)計，水電(dian)(dian)(dian)五局、七局負責大(da)壩(ba)、泄洪洞施工(gong)(gong)(gong)及(ji)機組安(an)(an)裝，水電(dian)(dian)(dian)十四局承擔廠房施工(gong)(gong)(gong)。開工(gong)(gong)(gong)建設(she)以來，工(gong)(gong)(gong)程(cheng)遭遇了(le)汶川特大(da)地震、響(xiang)水溝泥石流災害(hai)、蘆山地震、康定(ding)地震等自然(ran)災害(hai)影響(xiang)。參建企業，根據工(gong)(gong)(gong)程(cheng)實(shi)際情況精細設(she)計，科學施工(gong)(gong)(gong)，開展(zhan)大(da)量(liang)科研攻(gong)關，充(chong)分考慮(lv)類似(si)工(gong)(gong)(gong)程(cheng)經(jing)驗及(ji)新形勢(shi)下水電(dian)(dian)(dian)和諧、科學開發的需(xu)要，力求方案安(an)(an)全可(ke)靠(kao)、施工(gong)(gong)(gong)可(ke)行、經(jing)濟合(he)理、工(gong)(gong)(gong)期最優，為(wei)工(gong)(gong)(gong)程(cheng)順(shun)利推(tui)進、按時投產、提前(qian)發揮綜合(he)效應奠定(ding)了(le)堅實(shi)基礎(chu)，顯示出集團在(zai)巨(ju)、大(da)型水電(dian)(dian)(dian)工(gong)(gong)(gong)程(cheng)設(she)計施工(gong)(gong)(gong)方面具有雄厚的技術實(shi)力。
長(chang)河壩水電(dian)站位于四川省甘孜藏(zang)族自治州康(kang)定縣境(jing)內，為(wei)大(da)渡(du)河干(gan)流(liu)“3庫(ku)22級(ji)(ji)”開發的第10級(ji)(ji)電(dian)站，攔河大(da)壩最(zui)大(da)壩高240米(mi)，壩基覆蓋層厚度50余(yu)米(mi)，總(zong)裝機容量260萬千瓦，年發電(dian)量107.9億千瓦時。工程(cheng)具有超高邊坡(po)、超高土石壩、高地應力洞室群、強震區(qu)高進水塔(ta)、高流(liu)速大(da)功率泄洪、高強度大(da)型復(fu)雜洞室交通等(deng)特點，工程(cheng)設計與(yu)建設頗(po)具難度和挑戰。
