摘要水库兴利库容的计算是水库水利计算中重要的一环，其参数的计算精度直接影响着水库水利计算的可靠性。本文通过使用OriginPro2017软件对一个算例进行了的兴利调节计算，大概的介绍了年调节水库兴利库容的确定及Origin软件在水利计算方面的一些应用。本文主要采用灵敏度分析方法，分析了兴利调节计算中年调节水库兴利库容的确定过程中水库容积V、水面面积F、蒸发损失和渗漏损失四个参数对计算结果的影响程度。同时通过对四个参数灵敏度的计算比较，讨论了各参数的扰动对计算结果兴利库容值的影响，绘制出了灵敏度变化曲线。主要得出：兴利调节计算的计算结果兴利库容对水库容积V、水面面积F、蒸发损失和渗漏损失四个参数的误差具有缩小作用；水面面积F、蒸发损失和渗漏损失这三个参数的灵敏度相对较大，故合理选择这三个参数，可有效提高计算精度。关键词：水库兴利调节，兴利库容，灵敏度，时历法，年调节水库ABSTRACTThecalculationofutilizablecapacityisanimportantpartofreservoirwaterconservancycalculation,andthecalculationaccuracyofitsparametersdirectlyaffectsthereliabilityofreservoirwaterconservancycalculation.ByusingOriginPro2017software,thispapercalculatesanexample,andintroduceshowtodeterminethestoragecapacityofannualregulatingreservoirandsomeapplicationsofOriginsoftwareinwaterconservancycalculation.Inthispaper,thesensitivityanalysismethodisusedtoanalyzetheinfluenceofthefourparametersofreservoirvolumeV,watersurfaceareaF,evaporationlossandleakagelossonthecalculationresultsofthereservoirbenefitcalculate.Atthesametime,thesensitivityofthefourparametersiscalculatedandcompared.Theinfluenceofthedisturbanceofeachparameteronthecalculationresultsisdiscussed,andthesensitivityvariationcurveisplotted.Themainconclusionsareasfollows:thecalculationresultsofthereservoirbenefitcalculatecanreducetheerrorofthefourparametersofthereservoirvolumeV,thewatersurfaceareaF,theevaporationlossandtheseepageloss.ThesensitivitycoefficientsofthethreeparametersofwatersurfaceareaF,evaporationlossandseepagelossarerelativelylarge,soreasonableselectionofthesethreeparameterscaneffectivelyimprovethecalculationaccuracy.KEYWORDS:reservoirbenefitcalculate,effectivecapacityofreserloir,sensitivity,Durationmethod,annualregulatingreservoir目录第一章引言............................................................21.1水库水利计算的目的和意义.....................................................21.2国内外研究方法及研究现状.....................................................31.3研究内容和方法...............................................................6第二章水库水利计算和计算精度分析原理..................................72.1水库兴利调节.................................................................72.1.1水库特性.................................................................72.1.2兴利调节分类.............................................................82.1.3水量损失.................................................................92.2年调节水库兴利调节计算......................................................112.2.1水库兴利调节计算原理....................................................112.2.2水库兴利调节时历列表法..................................................122.3计算问题的性态和条件数......................................................13第三章基本数据与兴利调节计算算例.....................................133.1不计入水库水量损失的年调节计算.............................................163.2考虑水库水量损失的年调节计算...............................................183.2.1水...
