ABSTRACT = {We used a slightly modified version of Oda’s crack tensor theory for
developing and applying a modeling approach (that we characterize as a discrete
continuum) to upscale the hydraulic and mechanical properties of fractured rock
masses. The modified crack tensor theory was used to calculate the stress-dependent
permeability tensor and compliance tensor for the individual grid block. By doing
this, we transformed a discrete fracture network model into a grid-based continuum model. The methodology was applied to a benchmark test related to fluid
flow and transport through a 20 × 20 m model domain of heavily fractured media.
This benchmark test is part of the international DECOVALEX project, thus providing us with the opportunity to compare our results with the results of independent
models. We conducted the hydromechanical analysis with TOUGH-FLAC, a simulator based on the TOUGH2 multiphase flow code and FLAC3D geomechanical
code, using a multiple interacting continua (MINC) method to simulate the flow
and transport of fractured rock. The results of our simulations were consistent with
the results of the other independent modeling approaches.},
