摘要
在本钢郑家屯潜水含水层中进行了弥散试验，以Ｃｌ－为示踪剂，瞬时投放，根据流场条件，建立了二维水质运移模型。利用标准曲线法进行处理，得到了各监测井处的弥散度。对该试验结果进行分析，得到了在试验范围内，多孔介质中水动力弥散度的变化。
After having added instantaneously Cl- tracer to an injection well in a phreatic aquifer in Zhenjiatun,Bengang, dispersion experiment is conducted. Based on the hydrogeological condition, the paper established atwo-dimension model of water quality. According to the method of standard curives, the dispersivities were determines on monitering wells sets respectively. Having analysized the results successfully, we find that: in the testfield, there is a variation of dispersivity with the scale.
