黄河刘家峡水电站是以发电为主,兼有防洪、灌溉、防凌等综合利用效益的大型水电枢纽。运行十六年来,在西北地区国民经济建设中发挥了重大作用。但是,水库泥沙淤积带来的问题也逐渐暴露出来。 本文在分析水库实测资料的基础上,初步分析了水库泥沙冲淤规律,指出汛期泄流排沙和供水期末降低库水位冲沙是保持有效库容。控制洮河口沙坎发展及保证电站安全运行的重要措施。 水库蓄水以来,刘家峡水电厂进行了大量的水库泥沙测验工作,积累了宝贵的资料和经验。这些都是本文的基础,在此谨致谢意。。
The Yellow River Liujiaxia Hydropower Station is a large-scale hydropower hub that focuses on power generation and benefits from comprehensive utilization such as flood control, irrigation and anti-flood control. Since its operation for 16 years, it has played an important role in the national economy construction in the northwest region. However, the problems caused by the sedimentation of reservoirs are gradually exposed. Based on the analysis of the measured data, this paper analyzes the sediment scouring and sedimentation of reservoirs initially. It is pointed out that the discharge and sediment discharge in flood season and the reduction of reservoir water level at the end of water supply are the effective storage capacity. Control of Shahe estuary Shawan development and to ensure the safe operation of power plant important measures. Since the impoundment of reservoirs, Liujiaxia Hydropower Plant has carried out a large amount of reservoir sediment tests and has accumulated valuable information and experience. These are the basis of this article, I hereby thank you. .
