摘　　要：水库回水尖灭点是确定水库淹没处理终点位置的依据,影响水库淹没区范围。为探究回水尖灭点确定方法对水库淹没区面积的影响程度,文章以安徽省牛岭水库工程为例,分别依据水利水电工程和水电工程现行规范确定牛岭水库工程回水尖灭点,并以此推算牛岭水库工程的淹没影响范围,结果表明,水利水电工程方法确定的牛岭水库工程淹没区面积比水电工程方法多0.27%。牛岭水库工程淹没区面积受尖灭点确定方法的影响较小,但不同水库由于水文、地形等条件不同,受影响程度可能不一样,在规划设计过程中,应根据工程特点综合考虑各种条件因素,合理确定回水尖灭点。The peak extinction point of reservoir backwater is the basis for determining the end point of reservoir inundation treatment,which affects the scope of reservoir inundation area.In order to explore the degree of influence of the method of determining the backwater peaking point on the reservoir inundation area,this paper takes the Niuling Reservoir project in Anhui province as an example,determines the backwater peaking point of the Niuling reservoir project,based on the current norms of hydraulic and hydropower engineering and hydropower engineering respectively,and calculates the inundation impact range of the Niuling Reservoir project accordingly.The results show that,The inundation area of Niuling reservoir determined by the method of water conservancy and hydropower engineering is 0.27% more than that by the method of hydropower engineering.The inundation area of Niuling Reservoir is less affected by the method of determining the peaking point,but different reservoirs may be affected differently due to different hydrological and topographic conditions.In the planning and design process,various conditions should be considered comprehensively according to the characteristics of the project to determine the peaking point of the backwater reasonably.
