丰宁抽水蓄能电站泥沙淤积及防沙措施研究

通过丰宁抽水蓄能电站防沙问题的研究,阐述了此类电站泥沙淤积带来的工程问题以及通过建设下水库拦排沙系统、对拦沙库的洪水进行合理调度,使抽水蓄能电站在使用基准期内正常运行。通过泥沙淤积数学模型计算和物理模型试验对排沙措施和防沙效果进行了比较和分析。

Study on sediment deposition and sand prevention measure for Fengning pumped storage power station

Based on the sand prevention research for Fengning pumped storage power station,the paper introduces the engineer problems caused by sediment deposition of pumped storage power station,the station could operate normally in reference period through construction of sediment retaining and ejection system of lower reservoir and rational operation of flood for sediment retaining reservoir.The paper compares and analyzes sediment ejection measure and sand prevension effect through calculation of sediment depositi...
