%X Based on the double porosity concept,an approach is presented to derive a set of coupled differential equations governing behavior of porous fissured media. The finite element technique and code are employed for the solution of these equations by using Galerkin FEM. The relations,relating rock classification rating RQD and RMR,are developed to define the changes of effective porosity and hydraulic conductivity that result from the redistribution of strains in disturbed rock mass. At last,a hypothetical example is presented,and the obtained results are compared to these of the previous work.
