摘要

基于孔隙-裂隙岩体的双重孔隙介质流固耦合计算的微分方程，利用伽辽金有限元法提出的相应有限元公式，并基于岩体分类指标（RQD，RMR）提出了与岩体应力状态相关的渗透系数计算公式。编制了相应的有限元程序并给出了应用算例，将计算结果与相关文献作了比较，得出相关结论。

Abstract

An approach

which is based on the double porosity concept and takes into account pore deformation

has been presented to derive a set of coupled differential equation governing behaviour of porous fissured media. The finite element technique and code has been employed as the numerical methods for the solution of these equations by using of Galerkin finite element methods. Relations relating to rock classification rating RQD and RMR are developed to define changes in effective porosity and permeability that result from the redistribution of strains in disturbed rock mass. At last

an applied example is presented; the results are compared with ones of previous works.
