摘　　要：利用葛洲坝电站进行反调节可缓解三峡电站日调节运行时引起的下游河道水流波动,在保证两坝间水流条件满足航运要求的同时,尚应确保宜昌河段水流条件满足航运要求。研究表明,选择合理的葛洲坝电站反调节运行方式,可兼顾两坝间及宜昌河段水流条件满足航运要求;且三峡工程运行初期葛洲坝三江下引航道水深不足问题可通过工程措施来解决。By use of the anti-regulation of the Gezhouba hydropower station, the unsteady flows motion downstream caused by the daily regulation of Three Gorges hydropower station can be alleviated. The hydraulic conditions between the two dams would satisfy the requirements of navigation, at the same time it should insure that the hydraulic conditions of Yichang stream satisfy the requirements of navigation. Research results show that reasonable anti-regulation method of the Gezhouba hydropower station would make all hydraulic conditions between two dams and the Yichang stream to satisfy the requirements of navigation; and the unsufficient water depth in Sanjiang channel downstream of Gezhouba project can be resovled by the engineering measures during early operation of the Three Gorges Project.
