Abstract
Lu values obtained by Lugeon test are liable to be underestimated in open jointed rock. In this paper, we try to clarify the analytical relations between the injection pressure and the flow rate in the parallel smooth model and verify the relation experimentally. Finally we confirm applicability of the newly defined flow laws considering turbulent flow in order to evaluate the relation between Lu values and permeability, which is obtained by the viscous fluid in the Lugeon test, in the actual open jointed rocks.
