为调节和平衡长距离输水系统的流量，系统中一般设置一定库容的调节水库，其水力特性与各项功能是密不可分的。文章结合工程实际研究了调节水库进出口区域及库区整体上的流速分布，水流运动特性，并对不同运行工况下库内部分水体的最长滞留时间进行了分析估算。结果表明，库内水流流速较缓，在进、出水量不平衡条件下运行过程中，水流运动为有环流的三维流动，并且部分进库水体滞留时间偏长，存在富氧化而影响水质的风险，在类似的工程设计、运行和管理时，有必要进行进一步优化调整，以达到最优调节目的。

A regulating reservoir of certain capacity is generally set for the flow regulation and a balanced system in a long-distance water delivery project .Its hydraulic characteristics and functions are inseparable .This paper studies the velocity distribution and the flow characteristics at the entrance and exit and the whole reservoir .The longest retention time of the current in the reservoir under different operating conditions is analyzed . The results show that flow inside the reservoir is moderate ,and the flow movement process is a three-dimensional circulation in different inlet-outlet water yields .Portion of the water body in the reservoir delays fairly long and the water quality risks being decay because of the presence of enriched-oxygen .When a similar project is designed ,operated and managed ,it is necessary to further optimize it .
