摘　　要：核素随地下水在裂隙中的迁移与在孔隙中的迁移比较,不论从地下水与岩石的接触过程还是介质对核素的吸附作用来说都有很大不同。本文以国内某基岩裂隙场址低中放射性固体废物处置场为例,运用Ecolego软件对核素在裂隙中的迁移过程进行模拟,深入探讨了计算过程中的模型建立、参数选取等关键问题,并对计算结果进行了分析,得出裂隙对核素迁移影响的结论。Compared with the nuclides migration in the facture and pore, there are big diffirents no matter from the process of the contact about groundwater to rock or the adsorption effect about medium to the nuclides. This paper take radioactive disposal site under fissure bedrock for example, by using Ecolego software, simulate the process of nuclide migration in the fracture, and discuss the key issues about the caculation process between model establishment and parameters selection. The conclusion is that the fracture affect radionuclide migration in groundwater.
