于橋水庫(ku)位于天津(jin)市薊縣城東，是(shi)國家重(zhong)點大型水庫(ku)之(zhi)一，水庫(ku)壩址建于薊運(yun)河(he)左支流(liu)州河(he)出口處。
控制流(liu)域(yu)面積(ji)(ji)2060 k㎡，占整(zheng)個州(zhou)河(he)(he)(he)(he)流(liu)域(yu)面積(ji)(ji)的96%。州(zhou)河(he)(he)(he)(he)由沙河(he)(he)(he)(he)、淋河(he)(he)(he)(he)、黎河(he)(he)(he)(he)三大(da)支流(liu)匯(hui)合而成，各支流(liu)上游溝澗甚多(duo)(duo)，支流(liu)分散成輻(fu)射狀匯(hui)集于(yu)州(zhou)河(he)(he)(he)(he)盆(pen)地(di)，水(shui)庫(ku)庫(ku)區即位(wei)于(yu)該(gai)盆(pen)地(di)，最大(da)回(hui)水(shui)長(chang)東西約30km，南北寬8km，最大(da)淹沒(mei)面積(ji)(ji)250k㎡（正常蓄水(shui)位(wei)時淹沒(mei)面積(ji)(ji)86.8 k㎡）。州(zhou)河(he)(he)(he)(he)流(liu)域(yu)境內雨量充沛，多(duo)(duo)年平均降雨750mm，多(duo)(duo)年平均徑流(liu)量5.06億m3。水(shui)庫(ku)運用初期(qi)，曾出(chu)現過(guo)壩(ba)下游大(da)面積(ji)(ji)沼澤(ze)化(hua)、管涌等現象，唐山大(da)地(di)震后，主(zhu)河(he)(he)(he)(he)床附近(jin)壩(ba)段壩(ba)坡(po)腳(jiao)產生(sheng)裂縫，壩(ba)基出(chu)現砂(sha)層液化(hua)現象。
建立時間
該(gai)庫(ku)始建(jian)于1959年(nian)(nian)(nian)，1960年(nian)(nian)(nian)7月完成第(di)—期工(gong)程(cheng)(攔(lan)河壩(ba)、泄洪(hong)(hong)(hong)(hong)洞)。1965年(nian)(nian)(nian)續建(jian)開挖溢洪(hong)(hong)(hong)(hong)道(實(shi)際(ji)只開挖至23.0米(mi)高程(cheng))。水(shui)(shui)庫(ku)大(da)壩(ba)為(wei)一級建(jian)筑物，按千年(nian)(nian)(nian)一遇洪(hong)(hong)(hong)(hong)水(shui)(shui)設(she)計，最(zui)(zui)大(da)洪(hong)(hong)(hong)(hong)水(shui)(shui)校(xiao)核(he)(he)，抗震按8度設(she)防。水(shui)(shui)庫(ku)正常蓄(xu)水(shui)(shui)位(wei)21.16米(mi)，校(xiao)核(he)(he)洪(hong)(hong)(hong)(hong)水(shui)(shui)位(wei)27.72米(mi)。“75.8”河南(nan)大(da)水(shui)(shui)后，水(shui)(shui)庫(ku)被(bei)列為(wei)病險(xian)水(shui)(shui)庫(ku)，因此按千年(nian)(nian)(nian)一遇設(she)計，最(zui)(zui)大(da)可能(neng)洪(hong)(hong)(hong)(hong)水(shui)(shui)校(xiao)核(he)(he)標準對(dui)水(shui)(shui)庫(ku)進行除(chu)險(xian)加(jia)(jia)固(gu)(gu)，設(she)計洪(hong)(hong)(hong)(hong)水(shui)(shui)位(wei)25．62米(mi)，洪(hong)(hong)(hong)(hong)峰流(liu)量8327立方(fang)米(mi)/秒(miao)，校(xiao)核(he)(he)洪(hong)(hong)(hong)(hong)水(shui)(shui)位(wei)27.72米(mi)，洪(hong)(hong)(hong)(hong)峰流(liu)量17960立方(fang)米(mi)/秒(miao)。為(wei)保證引灤工(gong)程(cheng)輸(shu)水(shui)(shui)1982至1983年(nian)(nian)(nian)對(dui)大(da)壩(ba)實(shi)施(shi)了(le)加(jia)(jia)高壩(ba)頂、加(jia)(jia)固(gu)(gu)壩(ba)坡(po)及壩(ba)基截滲(shen)(shen)等工(gong)程(cheng)措施(shi)。1995年(nian)(nian)(nian)1996年(nian)(nian)(nian)采用高噴(pen)防滲(shen)(shen)墻(qiang)結合(he)壩(ba)后壓重的方(fang)法再次對(dui)大(da)壩(ba)進行了(le)局部(bu)加(jia)(jia)固(gu)(gu)處(chu)理。2001年(nian)(nian)(nian)至2003年(nian)(nian)(nian)再次對(dui)大(da)壩(ba)進行加(jia)(jia)固(gu)(gu)處(chu)理(包(bao)括(kuo)420米(mi)的防滲(shen)(shen)墻(qiang)，高壓噴(pen)射灌漿、補噴(pen)、接觸灌漿、現(xian)澆砼防浪墻(qiang)、減壓溝回填、壩(ba)后壓重、迎水(shui)(shui)坡(po)護砌(qi))。
工程構造
水(shui)庫樞(shu)紐工程有攔(lan)河壩(ba)(ba)(ba)、放(fang)水(shui)洞、溢洪道(dao)、水(shui)電站(zhan)。攔(lan)河壩(ba)(ba)(ba)為均(jun)質土壩(ba)(ba)(ba)，全長2222m，最大(da)壩(ba)(ba)(ba)高24m，壩(ba)(ba)(ba)頂高程28.72m。放(fang)水(shui)洞（兼發電洞）洞徑5m，壩(ba)(ba)(ba)后電站(zhan)設貫流式機(ji)組四臺，總裝機(ji)5000千瓦。溢洪道(dao)為開敞式堰閘，八孔閘門，凈寬(kuan)80m，最大(da)泄(xie)洪能(neng)力4138 m3/s。
水文特性
總庫容15.59億(yi)立方米(mi)，正(zheng)常蓄水位21.16米(mi)(大沽(gu))，汛限(xian)水位19.87米(mi)，死(si)水位15米(mi)。水庫下游直接影響范圍有薊縣(xian)、寶坻、寧河、玉田、漢沽(gu)等各縣(xian)（區）的低(di)洼地區近百萬人(ren)口，300余萬畝耕地。
風光特產
風景秀麗(li)、群山環繞的(de)于(yu)橋水庫坐(zuo)落在薊(ji)(ji)縣(xian)城東，又名翠(cui)屏湖(hu)，因南(nan)依翠(cui)屏山而得名。翠(cui)屏湖(hu)水面(mian)寬闊，東西(xi)長30公里(li)(li)，南(nan)北最寬處15公里(li)(li)。登翠(cui)屏山俯(fu)瞰，煙波(bo)浩淼，水天(tian)一(yi)色；蕩舟湖(hu)上，鷗浮上下，魚戲東西(xi)。南(nan)岸(an)(an)的(de)翠(cui)屏山綠(lv)(lv)樹成(cheng)蔭(yin)，花果滿園，葡萄壓枝。象一(yi)幅五彩(cai)斑(ban)斕(lan)的(de)畫卷。北岸(an)(an)山中古松蒼勁挺拔(ba)，建筑鱗次櫛比，層次豐(feng)富多變(bian)。西(xi)岸(an)(an)大(da)堤(di)橫(heng)臥，綠(lv)(lv)樹緣堤(di)，遠山如黛，云煙飄浮，極盡幻(huan)變(bian)幽深之趣(qu)。翠(cui)屏湖(hu)盛產魚蝦，尤(you)以金翅鯉(li)魚聞名天(tian)下，據《薊(ji)(ji)縣(xian)志》載：“鯉(li)魚產于(yu)薊(ji)(ji)運河者皆金鱗赭尾(wei)。”而今這種曾為皇帝貢品的(de)“御膳鯉(li)”巳成(cheng)為普通游人的(de)盤中珍品。
翠(cui)屏(ping)湖夏季氣(qi)候涼爽，是(shi)理(li)想的(de)避暑勝地。盛夏炎(yan)炎(yan)，眺翠(cui)亭旁的(de)平灘上，一群群穿著(zhu)游泳(yong)衣的(de)游人(ren)或(huo)坐或(huo)臥(wo)，悠然自得地沐浴著(zhu)陽光，人(ren)們紛(fen)(fen)紛(fen)(fen)下水(shui)游泳(yong)，任涼爽的(de)湖水(shui)沖散暑熱。水(shui)中(zhong)魚蝦避開了暢(chang)游的(de)人(ren)群，往來于紅(hong)蕖綠草之(zhi)間，招來了萬釣(diao)千竿。冬天，這里是(shi)滑冰、賞雪的(de)理(li)想場所。整個翠(cui)屏(ping)湖雪蓋冰封，銀(yin)裝素裹，滑冰愛好者紛(fen)(fen)至沓來。翠(cui)屏(ping)湖南(nan)岸(an)多農家院(yuan)旅店及(ji)活魚館，是(shi)都市人(ren)周末節假(jia)的(de)絕(jue)佳去處。水(shui)質優良(liang)的(de)翠(cui)屏(ping)湖湖域(yu)內(nei)有(you)120多種鳥(niao)類。每(mei)年4月初，水(shui)鳥(niao)多達(da)2萬多只，其中(zhong)有(you)被(bei)國家列為重(zhong)點(dian)保護的(de)大(da)天鵝、白鸛、白琵鷺等八種珍禽(qin)。
