Experimental study on the influence of non-cohesive sand gradation on the measurement of sediment concentration with turbidity method

  • 摘要: 利用浊度仪测量水流含沙量时,泥沙颗粒级配和矿物成分是影响浊度仪标定结果的主要泥沙因素。采用黄河原型非黏性沙配制不同粒径、不同含沙量浑水水体,开展固定粒径、粗细沙、混合沙等多组次试验研究,对黄河天然沙粒径及级配对浊度仪输出浊度的影响进行定量分析和机制探讨。结果表明:固定含沙量条件下,非黏性泥沙粒径对水体浊度的影响特征符合Mie散射定律;含沙量变化对浊度仪输出浊度的影响数量级为10~102,泥沙颗粒粒径变化对浊度仪输出浊度的影响数量级为10−1~1;相同含沙量条件下,悬沙比表面积与浊度仪输出浊度符合线性分布。建立了考虑非黏性沙级配影响的含沙量与浊度关系模型,能够较准确地反映非黏性沙粒径及泥沙浓度对水体浊度的影响,可为浊度与含沙量关系的准确率定及测量结果的校准提供可靠依据。
