1、工程水文及水利计算课程设计天福庙水库防洪复核计算 姓名：叶 文 杰 学号：2010311310 专业：水利水电工程 班级：10级水工1班一.设计任务1.选择水库防洪标准；2.历史洪水调查及插补；3.设计洪水及校核洪水计算4.调洪计算；5.坝顶高程复核。二.基本资料1.流域及工程概况天福庙水库位于湖北省安远县黄柏河东支的天福庙村，大坝流域面积553.6km2,河长58.2km,河道比降10.6，总库容6367万m3,是一座以灌溉为主，结合防洪、发电、拦沙、养殖等综合利用的水利工程。天福庙水库位置及水系见下图KS1-1.天福庙水库于1974年冬开工建成。大坝为浆砌石双曲拱坝，坝前河底高程348m，

2、坝高63.3m,电站总装机6040kw。水库死水位378m，死库容714万m3，正常蓄水位409m,相应库容6032万m3。设计水位（p=2%）409.28m,校核（p=0.2%）洪水位409.8，坝顶高程410.3m,防浪坝顶高程411.3m。库区吹程1000m。2.水文气象资料 气象特征,天福庙流域地处亚热带季风区，四季分明，夏季炎热多雨，冬季低温少雨，秋温高于春温，春雨多于秋雨，气温年内变化大，无霜期长。多年平均气温16.80C，历年最高气温400C,最低气温-120C，平均风速1.2m/s，多年平均最大风速15.5m/s，风向多为NE。流域年平均降雨量1036.3mm，流域暴雨频繁，洪

3、水多发，410月为汛期，汛期降雨量占全年降雨量的86.7%左右，尤其以7月最大，占全年的19.5%。月降雨量最少是12月，仅占全年的1.3%。3.水文测站 黄柏河干流上1958年设立池湾河水文站，1971年设立小溪塔水文站，1961年在东支设立分乡水文站。天福庙水库建成后，先后开展了降雨、水位、泄流观测，有比较完整的运行资料。分乡水文站是重要的参考站，控制流域面积1083.0km2.4.分乡站历史洪水。 根据1982年省雨洪办对宜昌市历史洪水调查成果的审定结果，分乡站洪水的排位为1935年、1984年、1826年、1930年、1958年，资料可靠，可直接采用。经审定认为，分乡站1935年洪水为

4、1826年以来的第一位，重现期为176年，1984年洪水与1926年、1930年、洪水相当，分别确定为1826年以来的24位，1958年洪水为1826年以来的第五位。分乡站历史洪水成果见下表分乡站历史洪水成果表序号年份洪峰流量（m3/s）1d洪量(x108m3) 3d洪量(x108m3) 重现期1193546801762198437391.07381.666431826419305195828201.22011.9500三.防洪标准选择 50年设计，1000年校核。四.峰、量选样级历史洪水调查1.天福庙水库坝址1959-1977年峰、量系列根据分乡站同期资料换算得来，洪峰按面积比指数的2/3次
