摘　　要：基于相似模拟条件,研究了垃圾渗滤液污染物在层状含水层中运移规律,通过数值模拟方法拟合了层状含水层的渗透性及弥散度,利用拟合参数分析了阜新垃圾填埋场有机污染物在地下环境中的迁移和时空分布规律,该实验和数值模型较好地反映了层状土中污染物渗漏的基本特征,对预测、控制渗滤液污染地下水提供了一种有效的方法。Under similar simulating conditions, the transport law of landfill leachate in a layered aquifer was described. The method of numerical simulation was used to fit the penetrability and dispersion of the layer aquifer, and the fitting parameters were used to analyze the transport and space-time distribution law of organic contaminants in the landfill at Fuxin in underground water. The experiment model reflected the characteristics of contaminant seepage in layered soil. This study provided an available approach to predicting and controlling the pollution of underground water by leaehate.
