泵站前池中泥沙沉积分析试验研究

Model Test Study on Mechanism of Sedimentation in Forebay of Pumping Station

运用相似理论、泥沙运动学等理论对泵站前池中泥沙沉积进行了受力分析 ,运用概率论和数理统计知识 ,分析泥沙运动机理 ,建立了起动流速和起动概率之间的关系 。

In this paper,the theories of similarity and sand dynamics are used to analyze the forces of sand sedimenation in forebay of pumping station.With the statistic and the probability to analyze the relations of critical velocity of sand suspension and critical percent of sand suspension is gained by analyzing the mechanism of sand movement.
