| Research Abstract |
To provide a set of governing equations for solving the coupled stress and fluid flow, a rock mass, which commonly contains a large number of geological discontinuities, is treated as an anisotropic, elastic porous medium with the corresponding elastic compliance and permeability tensors, hydro-mechanical equivalents to the discontinuous mass. The hydro-mechanical equivalents, with the special emphasis on the permeability tensor, are formulated on the assumption that cracks can be replaced by a set of parallel planar plates connected by two springs. Two-dimensional numerical analyses on seepage flow networks support the validity of the permeability tensor. Some field evidence is analyzed to examine the applicability of the present model for the practical purpose of rock hydraulics.
