Effective Elastic and Hydraulic Properties of Fractured Rock Masses with High Contrast of Permeability: Numerical Calculation by an Embedded Fracture Continuum Approach

Table 1

Selected parameters for the generation of the fractures network in the Sellafield fractured rock mass.

Fracture’s characteristics	Distribution	Selected parameters
Trace lengths	Power-law distribution	C = 4.0, D = 2.2 (rock masses with high density of fractures)
		Minimum cutoff lengths: 0.5 m
Orientations	Fisher's distribution	Joint set	Dip/dip direction (degrees)	Fisher constant (K)
		1	8/145	5.9
		2	88/148	9
		3	76/21	10
		4	69/87	10
Aperture	Uniform distribution	= 65 μm
Location	Poisson's distribution	The midpoint coordinates () of every fracture where (,) and (,) are coordinate ranges. are number in the range
