古(gu)洞(dong)口(kou)（Ⅰ級）水利水電(dian)工程位于(yu)湖(hu)北省興山(shan)縣(xian)(xian)境內，壩址在(zai)長江支流(liu)香(xiang)溪河(he)上(shang)游(you)古(gu)夫(fu)河(he)段的(de)古(gu)洞(dong)口(kou)峽谷出口(kou)處，下距興山(shan)縣(xian)(xian)新縣(xian)(xian)城古(gu)夫(fu)鎮2.5公(gong)里，距縣(xian)(xian)城高陽鎮18.5公(gong)里，為古(gu)夫(fu)河(he)流(liu)域水電(dian)開發的(de)近期骨(gu)干工程。

古洞(dong)口工(gong)程泄洪兼(jian)放空(kong)洞(dong)位于大壩左岸，圓塔式(shi)進(jin)水口的進(jin)口檢修閘(zha)室底板(ban)高程270.0米(mi)，弧形閘(zha)門位于隧洞(dong)中部，隧洞(dong)全長(chang)421米(mi)，均采(cai)(cai)用鋼(gang)筋砼(tong)襯砌，上(shang)游有壓段長(chang)183米(mi)，襯厚0.6米(mi)，由兩段方圓漸變段與檢修塔和工(gong)作閘(zha)室相接。下游無壓段長(chang)175米(mi)，出口采(cai)(cai)用斜切坎(kan)挑流(liu)消能。要(yao)(yao)求泄洪洞(dong)鋼(gang)筋砼(tong)施(shi)工(gong)必須(xu)保(bao)證質量，滿足抗沖、抗滲功能的要(yao)(yao)求，做到澆筑(zhu)密實、表面平(ping)整光滑。

古洞口(kou)工(gong)程(cheng)為Ⅱ等大（2）型工(gong)程(cheng)，主(zhu)要由(you)攔(lan)河(he)壩、泄(xie)(xie)洪建筑物(wu)(wu)、引(yin)水系(xi)統、廠(chang)房及開(kai)關站組成。壩址(zhi)處(chu)河(he)道峽窄,兩(liang)岸巖坡陡竣,河(he)床覆蓋層較深(shen)。且河(he)道自(zi)峽谷出(chu)口(kou)處(chu)急轉向右，右岸下(xia)游地勢開(kai)闊，交(jiao)通方便。根據壩址(zhi)地形、地質特點(dian)、及樞紐布置(zhi)要求，泄(xie)(xie)洪建筑物(wu)(wu)（即溢(yi)洪道和泄(xie)(xie)洪兼放空隧洞）布置(zhi)在左岸，引(yin)水系(xi)統及電站廠(chang)房布置(zhi)在右岸。

1、泄洪兼放空隧洞

泄(xie)洪(hong)(hong)兼放空隧(sui)洞(dong)位于大壩左(zuo)岸，由進水口(kou)、有壓段(duan)、工作閘室、無(wu)壓段(duan)及末端(duan)挑流鼻坎組(zu)成，全長421米，進水口(kou)底板高程為270米，校核洪(hong)(hong)水位時最(zui)大泄(xie)量(liang)1250立方米/秒。
