摘　　要：当某河流存在上游水库比下游水库校核洪水重现期低的情况,在计算下游水库校核水位时,上游水库大多已经超过校核洪水标准,理论上来说将发生漫坝的事件,应考虑上游水库溃坝对下游水库调洪造成的影响.本文以江西省新干县窑里水库为例,在上游小型水库是否溃坝工况下分别推求入库洪水过程,通过调洪演算计算出两种工况下的校核洪水位,得出上游水库溃坝对窑里水库校核洪水位的影响.结果表明:考虑上游溃坝情况下窑里水库校核洪水位比不溃坝时要高0.36m,在工程设计、安全鉴定复核时应注意其影响.When the check flood recurrence period of the upstream reservoir in a river is lower than the downstream reservoir,and calculating the check water level of the downstream reservoir,most of the upstream reservoirs have exceeded the check flood standard. In theory,dam overflow will occur,the impact of dam break in the upstream reservoir on flood regulation in the downstream reservoir should be considered. Taking Yaoli Reservoir in Xingan county of Jiangxi province as an example,this paper deduces the inflow flood process under the condition of whether or not the small upstream reservoir breaks,calculates the check flood level under the two conditions through flood routing and obtains the influence of upstream reservoir breaks on the check flood level of Yaoli Reservoir. The results show that the check flood level of Yaoli Reservoir is 0.36m higher than that of non-dam-break when considering the upstream dam-break. The influence of the check flood level should be paid attention to in engineering design and safety appraisal.
