摘要
随着地下水污染问题日益严重,越来越多的学者将溶质运移的弥散理论应用于研究地下水溶质运移规律,以对地下水中污染物的运移及发展趋势进行预测。该文以吉林省通化市某场地花岗岩风化壳网状裂隙承压含水层野外弥散试验为例,采用直线图解法、优选拟合法及径向流模型法等多种方法对研究区人工加速流场进行了参数估算,获得了人工加速流场下含水层的纵向横向弥散度和弥散系数。
With the groundwater pollution problem becoming more and more serious,more and more scholars use the dispersion theory of solute transport to study the law of groundwater solute transport to predict the transport and development trend of groundwater pollutants.Taking the field dispersion test of a granite weathering crust network fracture confined aquifer in Tonghua City of Jilin Province as an example,the parameters of artificial acceleration flow field in the study area are estimated by linear graphic method,optimization fitting method,radial flow model method and so on.The longitudinal and lateral dispersion persion ard dispersion coefficient are obtained.
