【摘要】 将裂隙岩体渗流视为裂隙网络流 ,核素仅在岩体裂隙网络流中迁移 ;核素在迁移过程中同时存在吸附和解吸作用 .基于图论和单一裂隙渗流的立方定律 ,建立了裂隙岩体裂隙网络渗流模型 ;在此基础上 ,考虑核素在裂隙网络流中迁移时既被裂隙表面吸附同时又发生解吸 ,建立了裂隙岩体核素迁移的二维稳态平衡和非平衡时间模型

【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.
