摘要
铀尾矿库中的放射性核素及重金属等有害物质随着渗水进入含水层后,将随地下水的运动而进行迁移。为了研究污染物在地下水中的迁移规律,采用二维稳定流数学模型对铀尾矿库周围地下水流场进行概化,并用Galerkin有限元法对模型进行了求解。将数值模拟的等水位线同实测的等水位线进行对比可以发现,两者拟合较好,将流场模拟的结果作为水质模型的输入参数是比较可靠的。
Radionuelides and heavy metals in uranium dam will seep to aqifer, then migrate with groundwater flow. In order to study the migrating rule of contaminants, a steady two dimentional mathematical model is adopted to simulate the groundwater flow field around the uranium milling dam, and the model is solved with Galerkin finite element method. Result shows that the calculated hydrograph fits the surveyed one very well. So it is reliable to input the simulated water line data to solute model as parameters.
