摘要
针对防洪治涝工程规划设计中河道(网)非恒定流调蓄方法复杂而难于在排涝工程中推广应用的问题,为简化河道(网)调蓄计算方法,分析了河道调蓄过程的各特征状态,由此提出了采用非均匀流水面线来计算河道最大调蓄动容量的方法,并用于考虑河道(网)调蓄作用的排水泵站排涝能力验算和泵站优化设计。实例计算说明该方法简便、有效,可供同类工程设计参考。
The regulation and storage calculation of unsteady flow in flood control and drainage engineering is too complicated to be widely applied in planning and design of flood control and drainage projects.Therefore,in order to simplify the regulation and storage calculation,we analyze the process features of regulation and storage and propose to calculate the maximum regulation and storage dynamic reservoir capacity by water surface profile of non-uniform flow.The practical drainage capacity calculation and pump station optimization design considering channel regulation and storage verified that the calculation method is simple,convenient and effective.
