摘　　要：以鲁北平原河道徒骇河为例进行梯级闸坝群洪水资源联合调度。考虑蓄洪控制水位、蓄水时机、生态流量、洪水利用率等约束条件在退洪阶段蓄洪,洪水调度分为敞泄、控泄两个典型阶段;以区间洪水源汇项作为过程输入,河道洪水演进过程采用一维水动力学法模拟,底孔出流水闸、溢流橡胶坝的闸坝开度过程分别采用闸孔出流、堰流公式按迭代法计算。模拟结果标明:偏枯年、平水年、偏丰年典型场次洪水的闸坝调蓄洪量分别为0.746、0.804、0.841亿m3,洪水量级越大则闸坝蓄满率越高,平水年、偏丰年闸坝基本能蓄满;泄流均不小于生态流量,未形成人造洪峰。Taking Tuhai River in north Shandong plain as an example to carry out flood resources joint regulation of sluice and dam group.Storge runoff during flood withdrawal considers control level,storage opportunity,ecological flow,and source use rate constraints.Flood regulation includes opening and controlling two discharge stages,using one-dimensional hydrodynamic method to simulate flood routing,using gate outlet and weir formula by iteration to calculate the opening process of the sluice and rubber dam.The results show that regulation storage in dry,normal and rainy year is respectively 74.6,80.4 and 84.1million m3,the full storage rate will be higher with flood magnitude increasing,and the storage is basically full in normal and rainy years,the discharge meets ecological base flow with no artificial flood peak.
