摘　　要：尼泊尔某水电站所处河流属于较为典型的高含沙量河流,该电站为调峰径流(PRoR)式高水头电站,防沙排沙尤为重要。笔者研究了以库代池方案的可行性和经济性,结合水文泥沙运行数值分析结果,采取较为合理的冲排沙设计及机组抗磨蚀措施,节省工程投资。该研究可为其他类似工程设计提供参考。The river where a hydropower station is located in Nepal is a typical river with high sediment concentration.The power station is a peak-shaving runoff(PRoR)high-head power station,and sand prevention and sediment discharge are particularly important.The authors studied the feasibility and economy of the replacing desilting basin with reservoirs scheme,combined with the numerical analysis results of hydrological and sediment operation,adopted a more reasonable flushing and desilting design and anti erosion measures for the unit to save engineering investment.This study can provide reference for other similar engineering design.
