5、.350.450.55根據(jù)安徽省廣德縣石門卡水庫除險加固工程初步設(shè)計報告（報批稿）石門卡水庫的匯水面積為6.85 km2。（4）水庫附近用水量情況。用水量分析石門卡水庫位于新杭鎮(zhèn)牛頭山村，屬在冊重點?。ㄒ唬┬退畮臁Ｋ畮斓募娣e6.58km2。水庫以灌溉、防洪為主，兼有工業(yè)用水和水產(chǎn)養(yǎng)殖功能。（1)農(nóng)業(yè)用水量水庫設(shè)計灌溉面積為2000畝，本次按照2000畝計算。根據(jù)相關(guān)規(guī)范，灌溉保證率為75%。根據(jù)計算，多年平均補(bǔ)充灌溉用水量55萬m3，p=75%保證率補(bǔ)充灌溉水量為66萬m3。由于灌溉技術(shù)水平的提高和灌溉工程的不斷完善，規(guī)劃水平年灌溉用水定額將有所降低，節(jié)約的灌溉用水量可用于增加灌溉面積，因

6、此，規(guī)劃水平年的農(nóng)業(yè)灌溉用水量將與現(xiàn)狀水平基本相當(dāng)。參照廣德縣盧村水庫及浙江省部分小型灌區(qū)的資料，渠系水利用系數(shù)為0.6。根據(jù)調(diào)查，水庫下游農(nóng)田主要種植單季稻，作物需水集中在69月。同時，參考廣德縣糧長門水庫工程水資源論證報告（報批稿），其毛灌溉定額及需水量如表5-4，其需水年內(nèi)分配系數(shù)見表5-5。表5-4 農(nóng)田毛灌溉定額及需水量計算表灌溉面積（畝）不同保證率灌溉定額（m3/畝）不同保證率需水（萬m3）50%75%90%50%75%90%2000290330360586672表5-5 廣德縣單季稻灌溉需水年內(nèi)分配月份123456合計各月用水比重0000048.3%100%月份789101112

7、各月用水比重24.0%23.6%4.1%000（2）工業(yè)用水量經(jīng)調(diào)查，分析范圍內(nèi)以石門卡水庫為水源的企業(yè)有廣德獨山南方水泥有限公司。廣德獨山水泥有限公司取水量為96.32萬m3/a。（3）生活用水經(jīng)調(diào)查，該地區(qū)生活用水為自來水，不從石門卡水庫取水。（4）滲漏損失量滲漏損失量包括水庫對地下水補(bǔ)給損失和閘（壩）滲漏損失。閘（壩）滲漏損失量是指壩基、兩翼及周邊滲漏三部分之和。壩基滲漏一般有實測資料，其它兩項可根據(jù)水文地質(zhì)條件進(jìn)行經(jīng)驗估算。沒有資料一般采用按閘蓄水量的百分比進(jìn)行推算，地質(zhì)良好地區(qū)為01%，地質(zhì)較差地區(qū)為1.53.0%。根據(jù)石門卡水庫水文地質(zhì)條件，閘（壩）滲漏損失量按上個旬平均蓄水量的1

8、%進(jìn)行估算。（5）蒸發(fā)損失蒸發(fā)損失就是指水庫蒸發(fā)損失。由于區(qū)域內(nèi)沒有蒸發(fā)量觀測資料，故借用臨近的廣德氣象站蒸發(fā)資料進(jìn)行計算。（6） 生態(tài)需水石門卡水庫建成以后，大壩下游河段減水，為保證減水段河道內(nèi)生態(tài)環(huán)境用水需要，需要從水庫下泄生態(tài)用水量。參考廣德地區(qū)的廣德縣糧長門水庫工程水資源論證報告（報批稿），在石門卡水庫壩址斷面處，河道內(nèi)生態(tài)需水用2個指標(biāo)進(jìn)行控制：1 最小生態(tài)流量以生態(tài)基流進(jìn)行控制，生態(tài)基流采用90%保證率月平均流量進(jìn)行估算，對于石門卡水庫，為0.013m³/s，每年下泄40萬m³。2 年內(nèi)生態(tài)環(huán)境總需水量以多年平均徑流量的百分比進(jìn)行確定，北方為1020%，南方為2

9、030%。對于石門卡水庫，多年平均徑流量為280.5萬m³，取20%，即56萬m³。因此石門卡水庫日常下泄最小生態(tài)流量為0.013m³/s，年內(nèi)還需另外下泄16萬m³的水量，以滿足河道內(nèi)生態(tài)環(huán)境總需水量56萬m³的要求。（7） 建設(shè)項目需水項目取水3504m3/d，項目系統(tǒng)年生產(chǎn)運行時間為330天，年取水量115.63萬m3。3、 設(shè)計內(nèi)容3.1 典型年選取 根據(jù)資料統(tǒng)計出1966年2010年的降雨量，并繪制出頻率曲線如附圖1，可得95%對應(yīng)的數(shù)值為840.2，所以選取的典型年是1996年10月1997年9月。3.2 水庫來水量計算水庫的來水量
