| 摘 要： | 针对高水头电站对引水防沙的特殊要求,本文结合优化取水口引水防沙结构布置,合理选择水库运行方式,确保过机含沙量在允许范围内(特别是d>0.1mm粗粒径泥沙),防止有害粒径对水轮机及过流部件的磨损,泥沙计算数学模型和物理模型都表明,烟岗首部枢纽采用水库沉降悬移质粗沙是可行的,确定的烟岗低闸运行水位是合理的,在流量不超过避峰流量55 m3/s时,数学模型计算结果和物理模型试验分析结果基本一致,沉降悬移质粗沙的效果达到沉沙池的标准,过机含沙量满足规范要求。

| Abstract: | Owing to high head power plant's special requirement for diversion sediment control,this paper optimized the structure layout of intake diversion sediment control and made reasonable choice of reservoir operation method to ensure that the turbine sediment is within the allowable range(especially for coarse sand d>0.1mm),to prevent the wear of harmful particle to turbine and over-current components.Sediment mathematical and physical models show that it is feasible to adopt reservior coarse suspended sediment... |
