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0 riginPro2017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0 rigin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人、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八、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。装关键词：水库兴利调节，兴利库容，灵敏度，时历法，年调节水库订线ABSTRACTThe calculation of utilizable capacity is an important part of reservoir waterconservancy calculation,and the calculation accuracy of its parameters directly affects thereliability of reservoir water conservancy calculation.By using OriginPro 2017 software,this paper calculates an example,and introduces how to determine the storage capacity ofannual regulating reservoir and some applications of Origin software in water conservancycalculation.In this paper,the sensitivity analysis method is used to analyze the influence of thefour parameters of reservoir volume V,water surface area F,evaporation loss and leakageloss on the calculation results of the reservoir benefit calculate.At the same time,thesensitivity of the four parameters is calculated and compared.The influence of thedisturbance of each parameter on the calculation results is discussed,and the sensitivity1装variation curve is plotted.The main conclusions are as follows:the calculation results of thereservoir benefit calculate can reduce the error of the four parameters of the reservoirvolume V,the water surface area F,the evaporation loss and the seepage loss.Thesensitivity coefficients of the three parameters of water surface area F,evaporation loss andseepage loss are relatively large,so reasonable selection of these three parameters can订KEY WORDS:reservoir benefit calculate,effective capacity of reserloir,sensitivity,Duration method,annual regulating reservoir线目录第一章引言…21.1水库水利计算的目的和意义..1.2国内外研究方法及研究现状31.3研究内容和方法…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…2.1.1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..11装2.2.1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..1313订3.1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3.2.1水库特性曲线的绘制..3.2.2计入损失的年调节列表计算..19线第四章分析讨论204.1水库容积V的灵敏度分析....214.2水面面积F的灵敏度分析22244.4渗漏损失的灵敏度分析..…254.5各参数灵敏度分析对比.27结语292930共37页第1页
