Abstract:
The fractures distribution and fracture rock mass permeation research is the premise condition that to study groundwater movement and pollutant migration in fracture rock mass in bed rock area, which includes the dominance orientation of fracture that groundwater fluxes in it, the brisk zone distribution of fracture water and the permeability calculation of rock mass. This paper mainly analyzes the fracture distribution and the dominance orientation of fracture and the permeability of a low-medium radioactive waste disposal field based on its rich geologic record. The following results are found through Statistical analysis and comparison calculation.The active zone of fractural water in bed rock is an active channel of active nucleus migration. Tthe headrace fracture of disposition have a dominant orientation. The penetrating coefficient tensor in bed rock fracture is also calculated.
