以江苏徐塘电厂炮车镇灰场为例，建立了炮车镇灰场及邻近地区地下水水质（污染）模型，并选用灰渣溶滤后产生的Ｆ－作为模拟因子，对地下水水位变化和Ｆ－浓度变化进行了数值模拟．最后利用模型对地下水中Ｆ－污染的范围和程度进行了预测．结果表明，模型可靠、合理、实用，为建立灰场后所可能引起的对地下水污染的预测预报提供了科学手段 Taking the ash yard of Gunba town of Xuantang Power Plant in Jiangsu Province as an example, the model of groundwater quality (pollution) in the ash field and the adjacent area of ​​Gunba town was established. The F- F-concentration changes were numerically simulated. Finally, the model was used to predict the extent and degree of F-pollution in groundwater. The results show that the model is reliable, reasonable and practical, which provides a scientific method for forecasting groundwater pollution that may be caused after establishing the gray field
