根据实测资料分析了三峡水库汛末蓄水对长江中游航道条件的影响,在此基础上,对正常运行期的蓄水调度方案进行了优化探讨.研究结果初步认为:目前水库蓄水时间必须提前至9月,宜昌下泄流量应大于10000~12000 m3/s,每日流量变幅不宜超过1500 m3/s.

Based on the measured data, the effects of the Three Gorges Reservoir filling at the end of the flood season on waterway condition in middle reach of Yangtze River were analyzed. On that basis, optimization of the reservoir operation mode in the normal operation period was discussed. The results generally show that the water storage time must be arranged in September early.The outlet discharge of Yichang should be greater than 10 000~12 000 m3/s, and the daily discharge variation amplitude should not be more than 1 500 m3/s.
