摘　　要：对二滩水电站尾水水位、流量和桐子林水电站坝前水位实测数据进行统计,分析了二滩水电站上、下游主要梯级水库电站对二滩水电站平、枯水期流量的影响,研究了桐子林水库蓄水初期不同坝前水位时二滩尾水水位-流量关系变化特征,计算了桐子林水库淤积20年、坝前水位1015 m时,二滩水电站4~6台机组满负荷发电时二滩尾水水位,给尾水河床护岸等修复工程提供了参考。The measured tail water level and flow rate of Ertan hydropower station as well as the data of sedimentation and water level upstream of Tongzilin hydropower station are analyzed,and the influence from main cascade hydropower stations upstream and downstream to the flow of Ertan hydropower station during normal and dry periods is studied,which provides the basis for further restoration works of the downstream river revetment.

关 键 词：尾水水位 枯水期流量 梯级水库电站 变化特征
