In this paper, the permeability of core zones of 6 large rockfill dams, are operated and managed by Korea Water Resources Corporation, were evaluated that estimated seepage rate by numerical seepage analysis fit to the measured seepage rate by varying the permeability by trial and error method. Seepage behavior through 6 large rockfill dams were estimated as stable condition because certain correlation between the seepage rate and the reservoir water level as the seepage rate rise and fall correspond to the reservoir water level rise and fall. From the evaluation results, evaluated permeability of core zones of 6 large dams were in the range from 6.0×10-6∼8.5×10-5cm/sec. It shows that water tightness of the core zones have no problem. |
