| 摘 要： | 三峡水库的修建改变了长江下游洪水特性,在分析长江沿岸工程设计洪水时,宜考虑三峡水库调度对长江中下游实测典型洪水的影响。本文采用还原计算方法对2012年7月洪水中三峡水库调度运用的拦洪削峰作用进行分析,本次洪水过程中,三峡水库调度运用降低了长江中下游干流各站水位,其中宜昌~沙市河段下降2.5m左右,城陵矶~汉口河段水位下降1.0m左右,九江~大通河段水位下降0.3m~0.5m左右。

| Abstract: | The Three Gorges Reservoir affects the characteristics of the Yangtze river downstream flood. The scheduling scheme of the Three Gorges Reservoir should be considered when calculating the design flood for engineering along the Yangtze River. The article analyzes the effects of scheduling scheme of the Three Gorges Reservoir on the floods in July 2012 by reduction calculation method.The Three Gorges Reservoir operation reduce the water level of the middle and lower reaches of the Yangtze River. The river water level fall about 2.5 m at the reaches of Yichang to Shashi City, Chenglingji to Hankou City drop of 1.0 m, Jiujiang to Datong City fall about 0.3m～ 0.5m. |
