The crack propagation resistance of rock, which is independent of the size of the crack for large cracks, was determined by analyzing results of the hydraulic fracturing experiments using the 10 m sized granite specimen at a quarry in Fukushima Prefecture, Japan. The method of analysis was the modified BEM, where the crack was assumed to be expanding as a semi-elliptical crack such that the stress intensity factor was approximately constant along its periphery. It was found that the crack propagation resistance of the granite being independent of crack size is 1.93 MPa·m1/2.
