查莫里(li)亞水(shui)電(dian)站是近(jin)5年來中國公司在尼泊(bo)(bo)爾承(cheng)(cheng)建(jian)(jian)的(de)(de)最大的(de)(de)水(shui)電(dian)工(gong)(gong)(gong)程(cheng)，建(jian)(jian)成(cheng)后將解決尼泊(bo)(bo)爾西(xi)部(bu)邊遠地(di)(di)區供(gong)電(dian)緊張狀況，同時可向(xiang)印度國家電(dian)網供(gong)應電(dian)力，促(cu)進當(dang)地(di)(di)社會經(jing)濟發展。電(dian)站位于尼泊(bo)(bo)爾西(xi)部(bu)喜馬拉雅山地(di)(di)區的(de)(de)查莫里(li)亞河上，靠近(jin)中尼邊境(jing)的(de)(de)西(xi)藏地(di)(di)區，設計壩(ba)(ba)高和壩(ba)(ba)長分(fen)別(bie)為54m和88m，總(zong)裝機容量(liang)為3萬KW，由尼泊(bo)(bo)爾政府(fu)投資(zi)興(xing)建(jian)(jian)，葛(ge)洲(zhou)壩(ba)(ba)集(ji)(ji)團(tuan)一公司施(shi)工(gong)(gong)(gong)總(zong)承(cheng)(cheng)包。查莫里(li)亞水(shui)電(dian)站通(tong)風洞工(gong)(gong)(gong)程(cheng)長152米，城(cheng)門(men)型(xing)結(jie)構，合同開(kai)挖總(zong)方量(liang)為1242立方米。因該工(gong)(gong)(gong)程(cheng)地(di)(di)處斷層(ceng)褶皺巖地(di)(di)帶，巖石破(po)碎嚴(yan)重，施(shi)工(gong)(gong)(gong)難度較大。葛(ge)洲(zhou)壩(ba)(ba)集(ji)(ji)團(tuan)一公司查莫里(li)亞項目部(bu)根據巖石特(te)性，采取(qu)人工(gong)(gong)(gong)挖掘(jue)、“短進尺、弱爆(bao)破(po)、強支護(hu)”相結(jie)合的(de)(de)方法作業，經(jing)過210天的(de)(de)艱(jian)苦奮戰(zhan)，終于實現了通(tong)風洞貫通(tong)的(de)(de)既定(ding)目標(biao)。
