Calculation Methods for the Permeability Coefficient of Concrete Face Rockfill Dam with Cracks

Table 7

Dam body materials and permeability coefficient k of rock (m/s).

Material	Concrete slab	Cushion	Transition layer	Major rockfill	Bedrock	Toe slab	Peripheral joints	Curtain	Rock	Parapet wall
k	2.85 × 10^−10	5.11 × 10^−6	5.57 × 10^−4	4.34 × 10^−2	1.5 × 10^−7	1 × 10^−10	1 × 10^−10	5 × 10^−8	1.5 × 10^−7	1 × 10^−10

In the analysis, the calculation conditions are normal water level (755.00 m), designed flood level (756.2 m), and check flood level (759.1 m).
