摘要：
This paper presents experimental results for hydraulic conductivity of rock joints (granite) under normal load without shearing or after shear displacements. A meso-scale model describing the flow changes, locally based on the cubic law, and taking into account the asperity degradation is proposed. This model uses two constitutive parameters and assumes that the change in maximum hydraulic opening and in normal relative displacement are the same. The tests mentioned hereabove are analysed by this model which shows a reasonable capacity of simulation and gives the maximum Reynolds number of the flow.
