摘　　要：北盘江马马崖一级水电站于2015年6月投产运行,为复核电站厂房尾水水位流量关系及对发电量影响,对下游河道断面进行实测并分析淤积变化,根据其下游马马崖二级坝址水位站拟定的天然水位流量关系,采用伯努利方程复核计算马马崖一级水电站厂房水位流量关系,复核分析发现厂房尾水中低水段较原可研设计时明显抬高,马马崖一级水电站的发电量略有减小,但不影响厂房防洪安全。Mamaya I Hydropower Station in Beipanjiang was put into operation in June 2015.In order to check the tailwater stage-discharge relation of hydropower house and its impact on electricity production,the downstream river section was measured and the siltation changes were analyzed.According to the natural stage-discharge relation drawn up by the water level station at the dam site of Mamaya II Hydropower Station,the stage-discharge relation of the powerhouse of Mamaya I Hydropower Station is calculated by using Bernoulli equation.The review analysis shows that the low water section in the tailwater of the powerhouse is obviously higher than that of the original feasibility study design,and the electricity production of Mamaya I Hydropower Station is slightly reduced,but it does not affect the flood control safety of the powerhouse.
