摘　　要：引水防沙是引水式水电站设计中的一项重要内容,也是引水式水电站运行管理中的难点。合理的引水防沙工程设计与科学合理的水库调度运用方式可以节省工程投资,提高电站的经济效益,并保持水库的可持续运行。文章结合国内外引水式水电站以库代池防沙方案,对目前工程中采用的双库方案、单库方案及单库分流方案等以库代池方案进行了分析,提出了影响以库代池防沙效果的关键因素包括工程设计方案与水库调度运用方式两个方面,并对其进行了探讨。Water diversion and sand prevention is an important aspect of the design of water diversion hydropower stations,and also a difficult point in the operation and management of water diversion hydropower stations.Reasonable design of water diversion and sand prevention projects,as well as scientific and rational reservoir scheduling and operation methods,can save engineering investment,improve the economic benefits of power stations,and maintain the sustainable operation of reservoirs.The article combines domestic and foreign diversion hydropower stations'sand prevention schemes using reservoirs instead of ponds,analyzes the current double reservoir scheme,single reservoir scheme,and single reservoir diversion scheme used in engineering,and proposes the key factors affecting the sand prevention effect of using reservoirs instead of ponds,including engineering design scheme and reservoir scheduling and operation mode,and discusses them.
