摘要
针对三峡—枝城河道的地形特征,建立一维非恒定流模型.在三峡电站预先给定的航运约束条件下,计算电站下游的非恒定流对航运的影响并对若干调峰流量过程曲线进行分析,找出满足航运要求的调峰曲线.提出可调整葛洲坝的库容水位关系,对三峡调峰流量进行反调节,削峰填谷,以满足航运要求.
In accordance with the topographic characteristics of the Three Gorges Zhicheng river section, a 1 D unsteady flow model is developed. The effects of unsteady flow on navigation are calculated for the lower reaches of the power station under the given navigation restrictions and a series of peak regulation flow rates. By analysis of various peak regulation curves, curves meeting the navigation requirement are drawn. Finally, it is pointed out that the peak regulation flow rate at the Three Gorges Power Station can be adjusted by modification of the reservoir capacity water level relationship of the Gezhouba Reservoir, so that the navigation requirement can be satisfied.
