摘　　要：对巴家嘴水库各运用时期库区的冲淤规律进行了研究,分析了不同排沙运用方式对库区冲淤的影响。结果表明:蓄水运用时期库区淤积严重,年均排沙比仅为0.043%;第一次自然滞洪运用时,水库淤积仍较为严重,第二次自然滞洪运用时期的库区淤积量比第一次的减少较多;蓄清排浑运用时期水库淤积量明显减少,排沙比为62.6%～77.8%。This paper made a study of scour and silt laws in different operating periods of Bajiazui Reservoir,and analyzed the influence of different operational modes for sediment flushing on scouring and silting of reservoir.The result shows that,a） the reservoir has a severe sedimentation in impoundment period and the annual average sediment release ratio is only 0.043%;b） the reservoir still has a relatively serious sedimentation in the first natural flood detention operation period,in the second natural flood detention operation period,sedimentation amount of the reservoir is reduced greatly;c） sedimentation amount of the reservoir decreases significantly in the operation period of storing clear and releasing muddy,with the sediment release ratio between 62.6%-77.8%.
