摘要:
根据水电站日调节波的特性，运用一维恒定流和非恒定流泥沙数学模型，分别计算了河道涨落水过程的水面线，在此基础上，用恒定流泥沙数学模型计算了三峡水库建库前后，其下游宜昌～沙市河段的水面线．并结合三峡和葛洲坝两电站联合运行的实际情况，研究了调节方案对三峡水库下游河道水面比降的影响。

Abstract:
Based on the characteristics of the daily regulation wave of hydropower stations, the water surface lines in the rising and falling stages are calculated by using an one-dimensional steady flow model and an unsteady flow sediment model. The water surface lines in the reach from Yichang to Shashi, downstream of the Three Gorges, before and after completion of the Three Gorges Reservoir are calculated by using a steady flow sediment model. Considering the joint operation of the Three Gorges and Gezhouba Hydropower Stations, influences of the daily regulation planning of the hydropower stations on the water surface slope of the downstream reach of the Three Gorges Reservoir are studied.
