摘要
汛期防洪调度是一类多目标、多阶段、多约束的复杂决策问题,合理控制不同层级橡胶坝的下泄水量是高效防洪调度的关键,提出梯级橡胶坝群汛期防洪调度优化方法。在考虑橡胶坝群周围水域环境的情况下,确定梯级橡胶坝群的组合形式;利用Copula函数估算梯级橡胶坝群汛期水量,计算单个橡胶坝汛期泄洪能力;优化求解梯级橡胶坝群塌坝泄洪调度量,确定防洪调度过程中需要塌坝的梯级橡胶坝数量;通过弧形开合状态的控制,实现梯级橡胶坝群汛期防洪优化调度。实测分析结果表明,在研究区域汛期时段内,通过优化设计防洪调度方法的应用,下游水位最大值为137 m,洪峰流量为652 m^(3)/s,与传统防洪调度方法相比超限量更低,即防洪调度效果更优。
Flood control operation in flood season is a kind of multi-objective,multi-stage and multi-constraint complex decision-making problem.Reasonable control of the discharge of rubber dams at different levels is the key to efficient flood control operation.An optimization method for flood control operation of cascade rubber dams in flood season is proposed.Considering the water environment around the rubber dam group,the combination form of the cascade rubber dam group is determined.Copula function is used to estimate the water quantity of cascade rubber dams in flood season and calculate the flood discharge capacity of a single rubber dam in flood season.Optimize the flood discharge scheduling of cascade rubber dams,and determine the number of cascade rubber dams that need to collapse during flood control scheduling.Through the control of arc opening and closing state,the optimal flood control operation of cascade rubber dams in flood season is realized.Through field measurement and analysis,it is concluded that during the flood season in the study area,the maximum downstream water level is 137m and the peak flow is 652 m/s,which is lower than the traditional flood control dispatching method,that is,the flood control dispatching effect is better.
