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(a

)为1.19~1.28 cm

横向弥散度(a

)经验推断值为0.24~0.26 cm。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。

Abstract

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 1.19~1.28 cm

the transverse dispersion degree experience value was 0.24~0.26 cm. It provides a sound basis for formulating effective measures to prevent and control groundwater pollution.
