摘 要:我国大江大河防洪系统已经或正在形成梯级水库联合防洪调度态势。梯级水库联合防洪调度可有效利用水库间防洪库容的补偿调节作用,在提高流域防洪减灾水平、洪水资源利用效益等方面具有重要作用。本文以汉江上游石泉-安康梯级水库防洪调度系统为研究对象,以20年一遇流域区间型洪水为例,建立了考虑河道流量演进的梯级水库防洪调度优化模型,分析了梯级水库间的防洪库容协调关系,该典型洪水下,石泉水库削峰率为14.82%,可分担安康水库部分防洪任务,并揭示了在保证石泉县、安康市防洪安全的情况下,石泉、安康水库防洪库容可变区间分别为0.80~0.98亿m3、2.89~3.60亿m3,研究结果可为流域防洪减灾提供技术支撑。The joint flood control operation mode of cascade reservoirs is being formed in China's River flood control system.The joint flood control operation of cascade reservoirs not only effectively utilizes the compensation and regulation function of flood control storage capacity between reservoirs,but also plays an important role in improving the level of flood control and disaster reduction and the utilization efficiency of flood resources.In this paper,the flood control operation system of Shiquan-Ankang cascade reservoirs in the upper reaches of Hanjiang River is studied.Taking the interval flood of twenty years return period as an example,this paper establishes a flood control operation optimization model of cascade reservoirs considering flow evolution of channel,with the coordination relationship of flood control storage capacity among cascade reservoirs analyzed.Under the condition of ensuring the safety of flood control in Shiquan County and Ankang City,the variable ranges of flood control storage capacity of Shiquan and Ankang reservoirs are of 80-98 million m 3 and 289-360 million m 3 respectively.The research results can provide technical support for flood control and disaster reduction.
