| 摘 要： | 为准确模拟预测放射性污染场地核素在土壤-地下水中动态迁移扩散的全过程,本文基于土壤及地下水中核素迁移扩散的数学模型,以Hydrus获取的动态核素浓度变化作为传递变量,代替GMS模型中固定源项,建立土壤-地下水核素迁移扩散的耦合模型,为我国放射性污染场地的地下水环境影响评价及污染治理的准确评价提供技术支持。

| Abstract: | In order to accurately simulate and predict the whole process of dynamic migration and diffusion of radionuclides in soil-groundwater radioactive contaminated sites, the study is based on the mathematical model of the migration and diffusion of radionuclides in soil and groundwater. Using the dynamic radionuclide concentration changes obtained by Hydrus as the transfer variable instead of the fixed source term in the GMS model establishes a coupling model of soil-groundwater nuclide migration and diffusion. The study provides technical support for the groundwater environmental impact assessment and the accurate assessment of pollution control of radioactive contaminated sites in my country. |
