某水库水文水力计算毕业设计--说明书

毕业设计（论文）说明书题目：长江流域某水库水文水利计算系名建筑工程系专业水利水电工程学号学生姓名指导教师2017年6月8日摘要长江流域是中国人口密集，经济最繁荣的地区，沿江重要城市有重庆、武汉、南京和上海。长江可供开发的水能总量达2亿千瓦，是中国水能最富有的河流。长江干流通航里程达2800多公里，素有三峡大坝“黄金水道”之称。长江流域的合理开发利用对我国城市建设和国民经济发展有着重要的利益影响。由此，在流域主、支流上兴建水库、堤坝等改善河道的水利工程是重点。该流域覆盖面广、落差大，下垫面形式复杂，历史上多次发生洪水等自然灾害，泥沙淤积等河道问题也有待解决。为有效解决其弊端因素，转弊为利，设计主要对在长江流域拟建水库某水库进行水文水利计算，主要包括入库径流分析、设计洪水分析、溢洪道堰顶高程的确定和水库各特征水位和特征库容确定。关键词：洪峰流量频率曲线;洪水过程线;特征水位ABSTRACTTheYangtzeriverbasinisoneofthemostdenselypopulatedareasinChina,withchongqing,wuhan,nanjingandShanghaiinimportantcitiesalongtheYangtzeriver.Withatotalcapacityof200gigawatts,theYangtzeriveristherichestriverinChina.TheYangtzeriverisknownasthegoldenwaterwayofthethreegorgesdam,whichismorethan2,800kilometerslong.TherationalexploitationandutilizationoftheYangtzeriverbasinhaveimportantbenefitsfortheconstructionofChinesecitiesandthedevelopmentofnationaleconomy.Therefore,theconstructionofwaterconservancyprojectssuchasreservoirsandDAMSonthemainandtributariesoftheriverbasinarethemainpoints.Thebasincoversawideareaandislarge,andthesurfaceofthebasiniscomplex,andtherehavebeenmanyfloodsandothernaturaldisastersinhistory.Inordertosolvethedisadvantagesfactorseffectively,turningdisadvantageforprofit,thedesignofareservoirintheYangtzeriverbasinoftheproposedreservoircalculationofhydrologyandwaterconservancyincludinginboundflowanalysis,thedeterminationofdesignfloodanalysis,spillwayweircrestelevationandreservoirfeaturesofwaterlevelandcapacityofeachset.Keywords:Floodfrequencycurve;Floodprocessline;Characteristicwaterlevel1目录第一章综合说明..................................................................11.1基本情况...............................................................................11.2基本资料...............................................................................11.2.1径流资料........................................................................11.2.2洪水资料........................................................................21.2.3农业用水........................................................................31.2.4城镇生活供水................................................................31.2.5农村生活供水................................................................31.2.6水库特性........................................................................3第二章入库径流分析..............................................................52.1水文资料审查.......................................................................52.1.1可靠性审查....................................................................52.1.2一致性审查....................................................................52.1.3代表性审查....................................................................52.2分析计算...............................................................................52.2.1划分水利年....................................................................52.2.2参数计算及频率曲线的绘制........................................62.2.3设计年内分配过程......................................................11第三章设计洪水分析............................................................143.1水文资料审查.....................................................................143.1.1可靠性审查..................................................................143.1.2一致性审查..................................................................143.1.3代表性审查..................................................................143.2分析计算.............................................................................143.2.1洪峰流量频率曲线......................................................143.2.2洪峰流量分析成果......................................................17第四章兴利调节....................................................................264.1死库容的确定.....................................................................264.2兴利调节计算方法及成果.................................................264.2.1农业用水计算..............................................................264.2.2城市生活用水计算......................................................2624.2.3农村生活用水计算......................................................264.2.4水量损失计算..............................................................264.2.5兴利调节成果..............................................................26第五章调洪计算................................................................305.1水库调洪计算的任务和基本原理.....................................305.1.1水库防洪调节计算的任务..........................................305.1.2水量平衡方程..............................................................315.1.3水库蓄泄方程..............................................................315.2列表试算法水库调洪计算.................................................325.2.1列表试算法水库调洪计算任务..................................325.2.2列表试算法水库调洪计算步骤..................................32第六章总结........................................................................34参考文献..................................................................................35附录..........................................................................................36外文资料中文译文致谢2017届本科生毕业设计（论文）1第一章综合说明1.1基本情况水库建设的任务主要为县城进行城镇供水，并兼顾下游的农业灌溉供水。该水库将承担着下游防洪任务，下游的防洪标准为20年一遇洪水，水库设计标
