摘　　要：以潇水流域水库群为研究对象,选取不同频干支流洪水遭遇下的流域组合洪水,建立潇水流域水库群联合防洪调度模型,并在此基础上引入动态规划-模式搜索算法(DP-PS)对模型进行求解,得到最为不利洪水情景下的调度方案。结果表明:当发生不同情景组合洪水时,涔天河水库最大削峰率均在70%以上,双牌水库最大削峰率均在28%以上;经涔天河水库优化调度后,江华县防洪风险率均为零(除7号洪水之外),道县防洪风险率均在18%以下。经双牌水库进行优化调度后,双牌县防洪风险率均在22%以下(除7号洪水之外)。零陵区防洪风险率均在34%以下。经过潇水流域水库群联合防洪优化调度后,江华县、道县、双牌县和零陵区4个防洪对象防洪效果显著。Taking the reservoir group in the Xiaoshui Basin as the research object,this paper builds a model of joint flood control operation of the reservoir group in the Xiaoshui Basin under combined floods from main and tributary rivers of different frequencies.On this basis,the dynamic programming-pattern search algorithm(DP-PS)is introduced to solve the model,and the operation scheme under the most unfavorable flood scenario is obtained.The results show that,under combined floods of various scenarios,the maximum peak clipping rate of Centianhe Reservoir is above 70%,and that of the Shuangpai Reservoir is above 28%.After the optimized operation of the Centianhe Reservoir,the flood control risk rate of Jianghua County is zero(except for flood No.7),and the flood control risk rate of Dao County is below 18%.After the optimized operation of Shuangpai Reservoir,the risk rate of flood control in Shuangpai County is below 22%(except for flood No.7),and the risk rate of flood control in Lingling district is below 34%.In conclusion,after the optimized operation of joint flood control of reservoirs in Xiaoshui Basin,remarkable flood control effects can be seen in Jianghua County,Dao County,Shuangpai County,and Lingling District.
