摘　　要：在以往研究成果的基础上,结合小浪底水库运用方式研究,通过数学模型计算了西霞院水库3种运用方案的运行效果,结果表明:3个方案的淤积量基本相当,方案二和方案三的淤积量略小于方案一的,因此从控制水库淤积方面考虑,方案二和方案三稍优;方案二在控制大流量和含沙量大于1 kg/m3浑水时的运用水位较高,能够在一定程度上增加水库发电量,从而增加效益。各方案均能满足长期保持西霞院水库反调节库容的要求,西霞院主汛期运用水位较低对控制水库淤积比较有利,但会损失一定的发电效益。On the basis of previous study achievements ,the operation effect of three kinds of operation schemes of Xixiayuan Reservoir were simula- ted and compared with mathematical model, in consideration with the study of operation mode of Xiaolangdi Reservoir. Through the results, it can be found that the sediment amount of three schemes is equivalent to each other and scheme two is a little less than scheme three. From the aspect of controlling sedimentation in the reservoir, scheme two and scheme three are better. In order to control large discharge and discharge containing sediment lager than 1 kg/m3 , the operation water level is higher in scheme two, which can help to generate electricity to some extent so as to in- crease profit. It can be concluded that each scheme can meet the demand of long-term preservation of compensation regulation storage capacity of Xixiayuan Reservoir. And it is beneficial to control sedimentation in reservoir for low water level operation in main flood seasons of Xixiayuan, but some power production benefits will be lost.
