中文摘要：
葛洲坝下游水位变化情况比较复杂,尤其在调峰过程中,准确把握下游水位的变化情况,分析研究变化规律,尤其是大流量调峰下的变化过程极为重要。通过建立水位变化模型,可为预测葛洲坝下游水位及计算葛洲坝电站出力,实施三峡～葛洲坝梯级水库优化调度提供技术支撑。

英文摘要：
The variation of the downstream water level in Gezhouba Hydropower Station is quite complex but important, especially during the peak load regulation process with large flow. A water level variation model is thus constructed by using the sensitivity analysis and the regression method. It could be used to forecast the downstream water level and to calculate the power output of Gezhouba Hydropower Station, which provides important technical support for the optimal dispatching of the Three Gorges-Gezhouba cascade reservoirs.
