【摘要】：根据《长江流域防洪规划》,长江上游已投入运行的、具有防洪功能的大型控制性水库总预留防洪库容超360亿m~3,亟需研究科学实用的防洪调度方法。在定义防洪库容互用性涵义的基础上,探讨了长江上游水库群间防洪库容的互用性,提出了基于库容互用性的水库群防洪调度方法。以金沙江下游梯级和三峡水库为例,分析了二者之间防洪库容的互用比例。研究结果显示,对于1981年、1982年和1998年3个典型年的洪水,金沙江下游梯级水库相对于三峡水库防洪库容的互用比例在0.80~0.97之间,并受拦蓄洪量比例和拦蓄时机的影响。在实时防洪预报调度中,可根据水库群所处状态及防洪形势,基于防洪库容互用性研究成果,结合水文气象预报,科学有效地调度洪水。
[Abstract]:According to the "Yangtze River Basin Flood Control Planning", the total reserved flood control capacity of the large controlled reservoirs with flood control function in the upper reaches of the Yangtze River exceeds 36 billion m ~ (3), which is in operation in the upper reaches of the Yangtze River. Therefore, it is urgent to study scientific and practical flood control operation methods. Based on the definition of interoperability of flood control reservoir capacity, this paper discusses the interoperability of reservoir capacity among reservoirs in the upper reaches of the Yangtze River, and puts forward a flood control operation method of reservoir group based on reservoir capacity interoperability. Taking the cascade of the lower Jinsha River and the three Gorges Reservoir as examples, the ratio of mutual use of flood control capacity between the two reservoirs is analyzed. The results show that for the three typical flood years of 1981, 1982 and 1998, the ratio of interoperation of cascade reservoirs to the flood control reservoirs of the three Gorges reservoir is between 0.80 and 0.97, which is affected by the proportion of flood volume and the timing of flood interception. According to the condition of reservoir group and flood control situation, the flood can be controlled scientifically and effectively according to the research results of reservoir capacity interoperability and hydrometeorological forecast in real time flood control forecasting.
