摘　　要：基于流固耦合和溶质运移理论,建立了垃圾渗滤液有机污染物运移耦合模型,用SOM法对所建的模型进行数值求解,利用该数值模型对垃圾渗滤液在地下水中迁移行为进行模拟,预测了污染物浓度的时空分布特征,对耦合、非耦合模拟结果结合实际监测数据进行对比,并对污染晕的大小、分布范围进行了数值模拟分析。结果表明,耦合模型模拟的污染物浓度变化趋势与监测值基本吻合,从而验证了耦合模型的可靠性和实用性。Based on the fluid-solid coupling and solution transport theory, the transport coupling model of organic contaminant in landfill leachate was established. The model was numerically solved by SOM method, which simulated the transport behaviors of organic contaminant of landfill leachate in groundwater. It predicted the temporal and spatial distribution features of contaminant concentration. The modeling results of coupling and uncoupling were compared with measured data respectively. And the contaminant plume areas and distribution range were numerically simulated. The results have shown that the changing trend of contaminant concentration simulated by the coupling model basically agreed with the measured data. Thus was verified that the coupling model was reliable and practical.
