摘　　要：通过对研究区的水文地质条件进行分析,建立田畈灰场的水文地质概念模型。选用灰渣溶滤后产生的F^-作为模拟因子,利用地下水模拟软件Visual MODFLOW对研究区地下水中的F^-的运移进行了数值模拟研究,对地下水中的F^-污染的范围和程度进行了预测。结果表明:氟化物在地下水中的运移方向与地下水水流方向基本一致,氟化物浓度随着迁移距离的增大而减小。为灰场地下水环境污染防治提供依据。The conceptual model of hydrogeology is developed based on analyzing the hydrogeological condition in the study area. Choose F^- of ash after leached as a simulation factor,then numerical simulation study of the migration of F^- in the groundwater using by the Visual MODFLOW groundwater simulation software,predicted the scope and entent of F^- in the ground water pollution. The results indicate that fluoride migration direction is consistent with groundwater flow direction,and fluoride concentration decreases with the increase of the migration distance. Simulation results can provide the basis for the groundwater environmental pollution prevention for pollution area.
