Steady-State Time Models of Nuclide Migration in Fractured Rock Mass
HE Shao-hui
Abstract：In this paper, seepage flow in fractured rock mass is regarded as flow in fracture network, and nuclides are migrated by the flow in fracture network. On the basis of graph theory and cubic law in a single fracture, steady-state model of seepage flow in fracture network has been established. Nuclides are absorbed in the process of migration in network flow and desorbed as well. Based on the above-mentioned steady-state model of seepage flow in fracture network, 2D steady-state equilibrium and non-equilibrium time models of nuclides migration have been established. Meanwhile, a case study is completed. The studies show that these models are reasonable. These models are able to be used to predict nuclides migration in fracture network in fractured rock mass.
