摘　　要：利用基于圣维南方程组的不稳定流推算方法,从下泄水流对下游河道的最大流速、最大水位变幅等的影响出发,分析利泽电站根据不同调峰工况调度运行时,这些航运水力要素受电站调峰影响时相应的变化情况,得出在满足下游航道通航要求时,电站推荐的调峰幅度范围。Based on the calculation of unsteady flow based on Saint-Venant equation set, this paper indicates the influence of discharge flow on the maximum velocity and the maximum water level amplitude of the downstream river, and the effect on navigation conditions of LiZe power station for hump modulation. The results show the recommended hump modulation range when the requirements of the downstream channel navigation are met.

关 键 词：利泽电站 调峰幅度 航运影响 非恒定流
