Abstract: Following the essential principles of Biot's three-dimensional consolidation theory, the govenring equations on the interacting media of a fluid and a solid are established after taking into account the markedest feature that the permeabilityrate of deformable porous media is the function of its deformation. The asymptotic solution of one-dimensional unstable coupled flow is obtained by applying initial layer correcting method. The cases calculation indicate that there are distinct difference between coupled flow and non-coupled flow. So these coupled effect cannot be ignored.
Keywords: deformable porous media, unstable flow, coupled filtration, initial layer correcting.
