摘　　要：为提高下游多泥沙河流的输沙能力,延长水库的使用寿命,设计了一种基于多泥沙河流系统模型(SRSS)的泥沙调节方法。首先,根据数据分析导出经验公式。然后,研究输沙关系以及泥沙淤积与来沙系数之间的响应关系。最后,对上游水库的运行方式进行了优化,从而最大限度地减少多泥沙河流下游侵蚀。仿真分析表明,所提出的优化运行模式可减少河道中5.43亿吨泥沙沉积。In order to improve the sediment transportation capacity of the downstream sediment laden river and prolong the service life of the reservoir,a sediment regulation method based on SRSS is designed in this paper.Firstly,the empirical formula is derived according to data analysis.Then,the sediment transportation relationship and the response relationship between sediment deposition and sediment inflow coefficient are studied.Finally,the operation mode of the upstream reservoir is optimized to minimize the downstream erosion of the sediment laden river.Simulation analysis proves that the proposed optimization operation mode can reduce 543 million tons of sediment deposition.
