ABSTRACT: The hydraulic
behaviour of a rock material structure is a major feature for its design and
safety assess- ment. Similar to all other physical problems, in
order to enclose the governing equations systems and achieve a solution, the
hydraulic characteristics of these materials need to be determined
experimentally and implemented then into adopted thermo-dynamical models. This
paper covers the process of the design, construction and operation of an
experimental rig built for this specific purpose. Using the constructed
large-scale permeameter, tests have been conducted. The non-linear hydraulic
behaviour of various mate- rials under extreme turbulent
conditions, where Reynolds number reaches unprecedented
values, has not been studied before. Preliminary results are presented and
discussed.
