| 中文摘要: |
| 基于某尾矿库水文地质条件的概化，运用二维潜水流及溶质运移耦合模型,对库中U(Ⅵ)的迁移过程进行了数值仿真.通过对比水头的测量值与模拟值，校正了模型参数并验证了模型的可靠性.运用校正后的参数，探讨了弥散度、阻滞系数和迁移时间对U(Ⅵ)在尾矿库地域地下水中迁移规律的影响，结果表明弥散度与阻滞系数均对U(Ⅵ)的迁移有影响，其中阻滞系数对本研究区U(Ⅵ)的迁移影响较大. |
| 英文摘要: |
| The migration of uranium in the groundwater of the mill-tailing was simulated by using the couple-model of the two-dimensional phreatic water and solute transport, based on the condition of generalized geohydrologic. Model parameters were calibrated and the reliability of the model was verified by comparing measured values of hydraulic head with simulated ones in observation wells. The influence of dispersion coefficient, retardation coefficient and time on the migration of U (Ⅵ) was discussed, respectively. The results showed that retardation coefficient made more difference to the migration of U (Ⅵ) than dispersion coefficient. |
