石盤水庫防汛基本一、工程概況石盤水庫是都江堰東風(fēng)渠六期工程（龍泉山灌區(qū)）的一座中型囤蓄水庫，水庫于1977年8月動(dòng)工修建，1979年5月建成。是以灌溉為主，兼有防洪、養(yǎng)殖、旅游等綜合效益的水利工程。水庫位于簡陽市石盤鎮(zhèn)境內(nèi)，地處絳溪河支流赤水河上游。水庫總庫容7670萬m3,有效庫容5238萬m3，設(shè)計(jì)灌面17.14萬畝,有效灌面13.11萬畝。水庫樞紐由主壩、6座副壩、溢洪道、放水放空設(shè)施、節(jié)制閘等組成。1、樞紐主要建筑物：主壩、副壩、溢洪道、放空洞、放水洞：主壩壩型屬粘土心墻石渣壩、壩頂高程461.00m、壩高52m、壩長252.4m;1#副壩壩型屬砌石重力壩、壩頂高程460.00m、壩高11.2m、壩長121m;2#副壩壩型屬粘土斜墻石渣壩、壩頂高程461.00m、壩高10m、壩長55m;3#副壩壩型屬砌石重力壩、壩頂高程460.00m、壩高9.7m、壩長51m;4#副壩壩型屬粘土斜墻石渣壩、壩頂高程461.00m、壩高10m、壩長354m;5#副壩壩型屬粘土斜墻石渣壩、壩頂高程461.00m.壩高8m、壩長90m;6#副壩壩型屬均質(zhì)土壩、壩頂高程461.001.5m、輸水涵洞長14.1m、最大放水流量4.5ms/s,低放水洞結(jié)構(gòu)型式為壓力隧洞、內(nèi)徑1.3m、輸水涵洞長163.2m、最大放水流量2.4ms/s。2、 水庫特征石盤水庫集雨面積84Km2,總庫容6960萬m3,校核洪水位459.00m,相應(yīng)庫容6960萬m3；設(shè)計(jì)洪水位459.00m,相應(yīng)庫容6960萬m3,正常蓄水位459.00m,相應(yīng)庫容6960萬m3,死水位446.00m,相應(yīng)庫容1722萬m3;放空水位446.00m,相應(yīng)庫容318萬m3,汛期防洪限制水位455.80m,相應(yīng)庫容5200.48萬m3。3、 流域、水文概況石盤水庫位于沱江水系絳溪河支流赤水河上游，控制集雨面積84.0km2,主河道長31.67km，河床平均比降8.1%。。赤水河發(fā)源于成都市龍泉區(qū)萬興場。流域呈羽形分布。地勢由北向南傾斜，相對高差150?400m，屬低山和淺丘地帶。水庫地處亞熱帶濕潤季風(fēng)氣候，氣候溫和，雨量較豐，四季分明。據(jù)簡陽市氣象資料統(tǒng)計(jì)：多年平均氣溫17.0°C，極端最高氣溫38.7^，極端最低氣溫一5.4C。多年平均相對濕度77%，多年開始蓄水，水位達(dá)到450米高程時(shí)，壩基滲漏嚴(yán)重，被迫空庫停蓄。1980年6月對基礎(chǔ)補(bǔ)做帷幕灌漿，進(jìn)行加固防滲。2001年庫水位459米時(shí)，主壩后坡出現(xiàn)300平方米的散浸,經(jīng)專家鑒定為白蟻穿壩蟻道所致，遂采取泄水保壩措施，庫水位降至458.10米，散浸現(xiàn)象消失，共泄水2376萬m3。2002年7月對主壩后坡進(jìn)行人工挖巢除白蟻，共清除116巢。2003年經(jīng)省水利廳組織對水庫大壩進(jìn)行安全鑒定為“三類壩”，并列入國家病險(xiǎn)水庫除險(xiǎn)加固整治計(jì)劃。2005年12月、2006年6月下達(dá)了石盤水庫除險(xiǎn)加固工程投資計(jì)劃，工程總投資1931.78萬元，2006年5月20日一期工程開工，2007年3月31日主體工程完工。目前安全隱患已經(jīng)消除。二、洪水調(diào)度方案和度汛方案（一）水庫特征值石盤水庫為中型型水庫，主壩為粘土心墻石渣壩，其設(shè)計(jì)洪水標(biāo)準(zhǔn)采用100年一遇（P=1%），校核洪水標(biāo)準(zhǔn)采用1000年一遇（P=0.1%）.水庫特征相應(yīng)庫容項(xiàng)目 水位（m） 備注汛限水位 458 0.6315 8月1日-9月30日（二） 汛期劃分：石盤水庫汛期為5月1日'-9月30日，其中5月1日-7月31日為主汛期，主汛期汛現(xiàn)水位457.0m,相應(yīng)庫容為0.5803億立方米，后期汛期汛限水位458m,相應(yīng)庫容0.6315億立方米。（三） 水庫調(diào)度的原則、方案：主要根據(jù)《防洪法》的規(guī)定和省、市防洪部門的要求，按照三岔水庫的洪水設(shè)計(jì)資料、本年度的氣象預(yù)報(bào)資料和灌區(qū)的用水計(jì)劃，科學(xué)制定本年度度汛方案。并申報(bào)資陽水利局防汛抗旱指揮部，經(jīng)批復(fù)后實(shí)施。石盤水庫為引洪充囤水庫，為年調(diào)節(jié)水庫，每年3-6月是灌區(qū)春灌用水時(shí)間，庫水位下降至455.0m-460.0m,七月水庫開始從都江堰引水充蓄，此時(shí)水庫有足夠空間調(diào)節(jié)本流域洪水。7-8月當(dāng)水庫充蓄到汛限水位時(shí)，在主汛期要嚴(yán)格控制東風(fēng)渠充庫水量，掌握好溢洪道的關(guān)閘時(shí)間，不突破汛限水位，使之保持足夠的滯洪庫容。如果在充水期間出現(xiàn)超頻率洪水，而且?guī)焖灰迅哂诳刂浦笜?biāo)時(shí)，則停止向水庫充水，可在北干渠的馬兒灘和夜河山泄洪閘泄洪，待控制了洪峰而不影響防洪時(shí)，再恢復(fù)向水庫充水至正常蓄水位。、匕/tt、一r心一、旦\\/rtilttet-t*、口/tt>-rA>士Ar人、匕/tt、一r心一、旦\\/rtilttet-t*、口三、 歷史洪水及其調(diào)查情況四、 目前存在的主要問題.水庫下游河道嚴(yán)重堵塞三岔水庫溢洪道和放空洞下游絳溪河河道，因水庫已運(yùn)行30余年，已被水土流失嚴(yán)重堵塞，河道被開墾種植農(nóng)作物、林木。河床高程已高于主壩三角埝溢流觀測高程，直接影響主壩的滲流觀測。也直接影響溢洪道和放空洞的正常排泄，為確保水庫安全度汛，希望國家安排防洪整治資金，進(jìn)行徹底整治，排除隱患，確保水庫和人民生命財(cái)產(chǎn)的安全。.防汛物資不足由于我處是自收自支的事業(yè)單位，水價(jià)標(biāo)準(zhǔn)低，每年收不抵支，資金缺口大，除安排一部分工作經(jīng)費(fèi)之外，防洪經(jīng)費(fèi)和防汛物資嚴(yán)重不足，根據(jù)資陽市和省防汛指揮部轉(zhuǎn)發(fā)國家防總關(guān)于《防汛儲(chǔ)備物資驗(yàn)收標(biāo)準(zhǔn)》和《防汛物資儲(chǔ)備定額編制規(guī)程》的通知要求，我處編制上報(bào)了水庫大壩防汛物資儲(chǔ)備計(jì)劃，望上級(jí)盡快安排相應(yīng)的防汛搶險(xiǎn)物資。
