摘要：

Experimental investigations indicate that shear zones arise at failure of the material, at which point permeability is reduced across the zones but increases by nearly 2 orders of magnitude parallel to them. The primary fabric of the host sediment also induces an anisotropy of permeability; values differ by an order of magnitude according to flow direction. The tortuosity of the fluid flow path is theoretically analyzed for shear zones produced in different combinations of uniaxial shortening and simple shear. -from Authors
