摘　　要：水电站投产运行后,尾水位由于各方面原因变动,对水电站运行也将造成一定影响,以新疆塔吉克二级水电站为例,尾水渠末端设置有坎宽顶堰,由最低尾水位计算堰顶高程,并由设计的有坎宽顶堰及最大设计流量计算最高尾水位。从而使水电站尾水不因下游渠道冲刷而变化。after hydropower station put into operation, the tail water level changed due to various aspects reason, and caused an influence on hydropower station operation. Taking Xinjiang Tajik secondary hydropower station as an example,the end of the tailrace set broad crested weir, this paper calculates weir crest elevation by the lowest levels, and calculates the highest tail water level by the broad crested weir and maximum design flow, so that the hydropower station tail water will not change due to downstream channel scour.
