摘要
水动力弥散理论主要研究地下水可溶物质在时间、空间上的变化和弥散运移规律,预测地下水污染的发展趋势。通过在包头市某厂区现场弥散试验所得的实测数据,利用标准曲线法进行了潜水含水层水动力弥散试验。测定结果表明,浅层含水层的纵向弥散度(aL)为1.19-1.28cm,横向弥散度(aT)经验推断值为0.24-0.26cm。研究结果可为厂区有效地下水污染防治措施的制订提供科学依据。
Hydrodynamic dispersion theory studies the temperoral and spatial changes in groundwater soluble substances and predicts the trend of groundwater pollution.This article carried out a dispersion test in the new Huamei factory site of Baotou City,and measured the longitudinal dispersion degree of the shallow aquifer.The results showed that the longitudinal dispersion degree was 1.19-1.28cm,the transverse dispersion degree experience value was 0.24-0.26cm.It provides a sound basis for formulating effective measures to prevent and control groundwater pollution.
