| 摘 要： | 当上游有水库,其防洪标准低于下游水库时,下游水库必须考虑上游水库溃坝洪水的影响.否则,会造成计算结果的差异.一旦出现溃坝,必将威胁下游水库的安全.综合国内外研究成果,以某中型水库大坝安全鉴定的水文计算为例,探讨上游溃坝洪水对下游水库调洪演算的影响,并给出上游存在多个这样的水库(防洪标准可不相同)时的处理方法,为类似工程提供参考.

| Abstract: | When there exists reservoir upstream,whose standard for flood control is lower then that in downriver,the dam-break flood upstream must be considered.Otherwise,the result is different.Once the upstream reservoir breaks dam,the downriver dam will be threatened.In this paper,on the base of research result in the world,taking the example of hydrological computation in the work of some dam safety evaluation,the influence to the downriver reservoir from the upstream is discussed.Moreover,the measure is also given when there exist several reservoirs(whose standard for flood control may be different) upstream,which offers reference for similar projects. |
