甘肅(su)省(sheng)天祝縣(xian)引(yin)(yin)大菜子溝水電(dian)站位于甘肅(su)省(sheng)天祝藏族自治縣(xian)挪(nuo)威(wei)村(cun)附近的(de)大通河(he)中游(you)河(he)段，引(yin)(yin)大入秦(qin)灌溉工(gong)程總(zong)干渠(qu)(qu)1#挪(nuo)威(wei)隧洞(dong)進(jin)口前(qian)，渠(qu)(qu)首至總(zong)干1＃隧洞(dong)進(jin)口前(qian)總(zong)長(chang)4277.78m(均(jun)為矩形及(ji)梯形明(ming)渠(qu)(qu))，渠(qu)(qu)線緊靠大通河(he)左岸山體坡腳布(bu)置，隨著渠(qu)(qu)線延伸渠(qu)(qu)、河(he)高程逐漸拉大，在(zai)總(zong)干1＃隧洞(dong)進(jin)口處渠(qu)(qu)底與大通河(he)高差已達20m左右。本段渠(qu)(qu)道主要采用漿砌塊石襯砌，渠(qu)(qu)道斷面(mian)較大，通過采用砼套襯進(jin)行改造減(jian)小糙率后，最大輸水能力(li)可提(ti)高到46m3/s，從而為電(dian)站的(de)發電(dian)引(yin)(yin)水創造了條件。
