古(gu)洞口（Ⅰ級）水利水電(dian)工程位于湖北省興(xing)山縣境內，壩址在長江支(zhi)流香溪(xi)河上游古(gu)夫(fu)河段的(de)古(gu)洞口峽(xia)谷出口處(chu)，下距(ju)興(xing)山縣新縣城古(gu)夫(fu)鎮(zhen)(zhen)2.5公(gong)里，距(ju)縣城高陽鎮(zhen)(zhen)18.5公(gong)里，為古(gu)夫(fu)河流域(yu)水電(dian)開發的(de)近期骨(gu)干(gan)工程。

古(gu)洞口(kou)工程泄洪兼放空洞位于大壩(ba)左岸，圓塔(ta)式進(jin)水口(kou)的進(jin)口(kou)檢修(xiu)閘室(shi)底板高(gao)程270.0米(mi)，弧形(xing)閘門位于隧洞中部，隧洞全長(chang)421米(mi)，均采(cai)用(yong)鋼筋砼(tong)襯砌，上游(you)有壓段(duan)長(chang)183米(mi)，襯厚0.6米(mi)，由兩段(duan)方圓漸變段(duan)與檢修(xiu)塔(ta)和工作閘室(shi)相接。下游(you)無壓段(duan)長(chang)175米(mi)，出口(kou)采(cai)用(yong)斜切坎挑流消(xiao)能(neng)(neng)。要求泄洪洞鋼筋砼(tong)施工必須保證質量，滿足抗(kang)沖、抗(kang)滲(shen)功能(neng)(neng)的要求，做到澆筑密實、表面(mian)平整光滑。

古洞口工(gong)程為Ⅱ等大（2）型(xing)工(gong)程，主要(yao)由攔河壩、泄(xie)(xie)洪建(jian)筑物(wu)、引水系統、廠房(fang)及開關(guan)站(zhan)(zhan)組成(cheng)。壩址處河道峽窄,兩岸巖坡陡竣,河床覆蓋層較深。且(qie)河道自峽谷出口處急轉向右，右岸下游地勢(shi)開闊，交通(tong)方便。根據壩址地形、地質特(te)點、及樞紐布(bu)(bu)置(zhi)要(yao)求，泄(xie)(xie)洪建(jian)筑物(wu)（即溢洪道和泄(xie)(xie)洪兼放空隧洞）布(bu)(bu)置(zhi)在(zai)左岸，引水系統及電站(zhan)(zhan)廠房(fang)布(bu)(bu)置(zhi)在(zai)右岸。

1、泄洪兼放空隧洞
