于(yu)橋水庫位于(yu)天津市薊(ji)縣城東(dong)，是國家重點大(da)型水庫之一，水庫壩址建于(yu)薊(ji)運(yun)河(he)左(zuo)支(zhi)流州河(he)出口處。
控制流(liu)域(yu)面(mian)積(ji)2060 k㎡，占(zhan)整(zheng)個(ge)州河(he)(he)(he)(he)流(liu)域(yu)面(mian)積(ji)的96%。州河(he)(he)(he)(he)由(you)沙河(he)(he)(he)(he)、淋(lin)河(he)(he)(he)(he)、黎(li)河(he)(he)(he)(he)三(san)大支(zhi)流(liu)匯合(he)而成，各(ge)支(zhi)流(liu)上游溝澗甚多(duo)(duo)，支(zhi)流(liu)分散成輻射狀匯集(ji)于州河(he)(he)(he)(he)盆(pen)地(di)，水庫庫區即位(wei)于該盆(pen)地(di)，最(zui)大回水長東西約30km，南北寬8km，最(zui)大淹沒(mei)面(mian)積(ji)250k㎡（正常蓄水位(wei)時淹沒(mei)面(mian)積(ji)86.8 k㎡）。州河(he)(he)(he)(he)流(liu)域(yu)境(jing)內雨量充沛，多(duo)(duo)年(nian)平均(jun)降雨750mm，多(duo)(duo)年(nian)平均(jun)徑流(liu)量5.06億(yi)m3。水庫運用初期(qi)，曾出現過壩下游大面(mian)積(ji)沼(zhao)澤化、管涌等現象(xiang)，唐山大地(di)震后，主河(he)(he)(he)(he)床附近壩段壩坡腳產生裂縫(feng)，壩基(ji)出現砂層(ceng)液(ye)化現象(xiang)。
建立時間
該庫(ku)(ku)始建于1959年(nian)(nian)(nian)(nian)，1960年(nian)(nian)(nian)(nian)7月完成第—期工(gong)程(cheng)(cheng)(攔河(he)壩(ba)(ba)(ba)(ba)(ba)(ba)、泄洪(hong)(hong)洞)。1965年(nian)(nian)(nian)(nian)續建開(kai)挖溢洪(hong)(hong)道(實際只開(kai)挖至(zhi)23.0米(mi)高程(cheng)(cheng))。水(shui)(shui)(shui)庫(ku)(ku)大(da)(da)(da)(da)壩(ba)(ba)(ba)(ba)(ba)(ba)為一(yi)(yi)級建筑物，按(an)千年(nian)(nian)(nian)(nian)一(yi)(yi)遇(yu)洪(hong)(hong)水(shui)(shui)(shui)設(she)(she)計，最大(da)(da)(da)(da)洪(hong)(hong)水(shui)(shui)(shui)校(xiao)核(he)，抗(kang)震按(an)8度設(she)(she)防。水(shui)(shui)(shui)庫(ku)(ku)正常(chang)蓄水(shui)(shui)(shui)位(wei)(wei)21.16米(mi)，校(xiao)核(he)洪(hong)(hong)水(shui)(shui)(shui)位(wei)(wei)27.72米(mi)。“75.8”河(he)南大(da)(da)(da)(da)水(shui)(shui)(shui)后，水(shui)(shui)(shui)庫(ku)(ku)被(bei)列為病險(xian)水(shui)(shui)(shui)庫(ku)(ku)，因此按(an)千年(nian)(nian)(nian)(nian)一(yi)(yi)遇(yu)設(she)(she)計，最大(da)(da)(da)(da)可能洪(hong)(hong)水(shui)(shui)(shui)校(xiao)核(he)標(biao)準對(dui)水(shui)(shui)(shui)庫(ku)(ku)進(jin)行除險(xian)加(jia)(jia)固，設(she)(she)計洪(hong)(hong)水(shui)(shui)(shui)位(wei)(wei)25．62米(mi)，洪(hong)(hong)峰流量8327立方米(mi)/秒，校(xiao)核(he)洪(hong)(hong)水(shui)(shui)(shui)位(wei)(wei)27.72米(mi)，洪(hong)(hong)峰流量17960立方米(mi)/秒。為保證(zheng)引(yin)灤工(gong)程(cheng)(cheng)輸水(shui)(shui)(shui)1982至(zhi)1983年(nian)(nian)(nian)(nian)對(dui)大(da)(da)(da)(da)壩(ba)(ba)(ba)(ba)(ba)(ba)實施了加(jia)(jia)高壩(ba)(ba)(ba)(ba)(ba)(ba)頂、加(jia)(jia)固壩(ba)(ba)(ba)(ba)(ba)(ba)坡及壩(ba)(ba)(ba)(ba)(ba)(ba)基截滲等工(gong)程(cheng)(cheng)措施。1995年(nian)(nian)(nian)(nian)1996年(nian)(nian)(nian)(nian)采用高噴(pen)(pen)防滲墻結合壩(ba)(ba)(ba)(ba)(ba)(ba)后壓(ya)重的方法再次對(dui)大(da)(da)(da)(da)壩(ba)(ba)(ba)(ba)(ba)(ba)進(jin)行了局部加(jia)(jia)固處理。2001年(nian)(nian)(nian)(nian)至(zhi)2003年(nian)(nian)(nian)(nian)再次對(dui)大(da)(da)(da)(da)壩(ba)(ba)(ba)(ba)(ba)(ba)進(jin)行加(jia)(jia)固處理(包(bao)括420米(mi)的防滲墻，高壓(ya)噴(pen)(pen)射(she)灌(guan)漿、補噴(pen)(pen)、接觸灌(guan)漿、現澆砼防浪(lang)墻、減壓(ya)溝回(hui)填、壩(ba)(ba)(ba)(ba)(ba)(ba)后壓(ya)重、迎(ying)水(shui)(shui)(shui)坡護砌(qi))。

風光特產
風景秀麗、群山環繞的于(yu)橋(qiao)水(shui)庫坐落在薊縣(xian)城(cheng)東(dong)，又名(ming)(ming)翠屏湖(hu)(hu)，因南依翠屏山而(er)得名(ming)(ming)。翠屏湖(hu)(hu)水(shui)面寬闊，東(dong)西長30公里，南北最寬處(chu)15公里。登翠屏山俯(fu)瞰，煙波(bo)浩淼，水(shui)天(tian)一色(se)；蕩舟湖(hu)(hu)上，鷗浮上下(xia)，魚(yu)(yu)戲東(dong)西。南岸(an)的翠屏山綠樹成(cheng)蔭，花果滿(man)園，葡萄壓枝。象一幅五彩斑斕的畫(hua)卷。北岸(an)山中(zhong)古松蒼勁(jing)挺拔(ba)，建(jian)筑鱗(lin)次櫛(zhi)比(bi)，層次豐富(fu)多(duo)變(bian)。西岸(an)大(da)堤橫(heng)臥，綠樹緣堤，遠山如黛，云(yun)煙飄浮，極盡幻變(bian)幽深之趣。翠屏湖(hu)(hu)盛產魚(yu)(yu)蝦，尤(you)以金翅鯉(li)魚(yu)(yu)聞名(ming)(ming)天(tian)下(xia)，據《薊縣(xian)志》載(zai)：“鯉(li)魚(yu)(yu)產于(yu)薊運河者皆(jie)金鱗(lin)赭尾。”而(er)今這種曾為皇帝貢品的“御(yu)膳鯉(li)”巳成(cheng)為普通游人的盤(pan)中(zhong)珍品。
