Estimating methods found in the literature are used in an attempt to predict the measured hydraulic and thermal conductivities of the crushed granite materials. The results show that the hydraulic conductivity model of Chapuis generally yields accurate estimated values for d 10 2 n 3 / (1-n) 2 larger than 0.01 mm 2. Below this critical point ...
