三峡水库运行对支流水库影响分析

以龙盛水库为例,按照三峡水库典型调度运行方式,建立一维数学模型,推求出三峡水库调度影响下御临河口长江水位(即龙盛水库坝下水位);并以典型年的时段划分方法,分析龙盛水库对应与三峡水库回水水位的关系,得出典型年时段下三峡水库坝前调度水位对应的龙盛水库调度曲线。对三峡水库运行下坝前水位、支流水库坝后水位及其坝前水位三者关系作出了分析。

Influence analysis of the Three Gorges Reservoir operation on reservoir in branch river

Taking Longsheng reservoir as an example,a one-dimensional mathematical model was established according to the typical dispatching operation of the Three Gorges Reservoir.Then the water levels at the confluence of Yulin river and the Yangtze River were calculated.Based on the period division method of the typical year,the relationship between the water levels in Longsheng reservoir and fluctuating backwater of the Yangtze River was analyzed.The curve of dispatch plan of the Longshen reservoir corresponding to the water levels of the Three Gorges Reservoir was obtained,and the relationship among water level caused by the operation regulation of the Three Gorges Reservoir,downstream water level and upstream water level was also studied in this paper.
