本文运用准沉静法,在分析顺、逆坡沉沙池水流、泥沙运动过程的基础上,进一步给出了顺、逆坡沉沙地沉淀效率的差值;并以黄河中游大禹渡泥沙级配为分析样本,经计算表明,逆坡沉沙池较顺坡沉沙池沉淀效率提高15％左右。
Based on the quasi-calm method and the analysis of the flow and sediment movement in the cis-descending sand basin, the difference of sedimentation efficiency between the cis-descending slope and the descending slope was given. Sand grade with the analysis of samples, the calculation shows that the reverse slope desilting pool sedimentation efficiency than the slope sedimentation tank increased by about 15%.
