古(gu)洞口(kou)（Ⅰ級）水(shui)(shui)利水(shui)(shui)電工程(cheng)(cheng)位于湖北(bei)省(sheng)興山(shan)縣境內(nei)，壩址在長江支流(liu)香溪河(he)(he)上游古(gu)夫(fu)(fu)河(he)(he)段的(de)古(gu)洞口(kou)峽谷(gu)出口(kou)處，下距興山(shan)縣新縣城古(gu)夫(fu)(fu)鎮2.5公里(li)，距縣城高陽鎮18.5公里(li)，為古(gu)夫(fu)(fu)河(he)(he)流(liu)域水(shui)(shui)電開發的(de)近期骨干工程(cheng)(cheng)。

古(gu)洞(dong)口(kou)工(gong)程泄洪(hong)兼放空洞(dong)位(wei)于大壩左岸，圓(yuan)塔式進(jin)水口(kou)的進(jin)口(kou)檢修閘(zha)(zha)室底(di)板高程270.0米，弧形閘(zha)(zha)門位(wei)于隧(sui)洞(dong)中部，隧(sui)洞(dong)全長(chang)(chang)421米，均采用鋼筋砼襯(chen)砌，上游有(you)壓段(duan)(duan)長(chang)(chang)183米，襯(chen)厚(hou)0.6米，由兩段(duan)(duan)方圓(yuan)漸變段(duan)(duan)與(yu)檢修塔和工(gong)作閘(zha)(zha)室相接。下游無壓段(duan)(duan)長(chang)(chang)175米，出口(kou)采用斜(xie)切坎(kan)挑流消能。要求泄洪(hong)洞(dong)鋼筋砼施(shi)工(gong)必(bi)須保(bao)證質量，滿足(zu)抗沖、抗滲功能的要求，做(zuo)到(dao)澆筑密實、表面(mian)平整光滑。

古洞口工程為Ⅱ等大（2）型(xing)工程，主要由(you)攔河壩(ba)、泄(xie)洪(hong)建(jian)(jian)筑物(wu)、引水系統(tong)、廠房及(ji)開(kai)關站(zhan)組(zu)成。壩(ba)址處河道峽窄,兩岸(an)巖坡陡竣,河床覆(fu)蓋(gai)層(ceng)較深。且河道自峽谷出口處急轉向右(you)，右(you)岸(an)下游地勢(shi)開(kai)闊，交(jiao)通方(fang)便。根據壩(ba)址地形、地質特點、及(ji)樞紐布(bu)置要求，泄(xie)洪(hong)建(jian)(jian)筑物(wu)（即(ji)溢洪(hong)道和泄(xie)洪(hong)兼放空(kong)隧洞）布(bu)置在左岸(an)，引水系統(tong)及(ji)電(dian)站(zhan)廠房布(bu)置在右(you)岸(an)。

1、泄(xie)洪(hong)兼放空隧(sui)洞

泄洪兼(jian)放空(kong)隧洞位于大(da)壩左岸，由(you)進(jin)水(shui)口、有壓段、工作閘(zha)室、無(wu)壓段及末端挑流鼻坎組成，全長421米(mi)，進(jin)水(shui)口底板(ban)高程(cheng)為270米(mi)，校核洪水(shui)位時最大(da)泄量1250立方米(mi)/秒(miao)。
