摘要：

Porous medium can be reckoned as one of the most common existences in natural or artificial environment, and many engineering problems such as the wave propagation problem and the flow and heat transfer problem in porous medium have been modeled and solved. The most important character of porous medium is the layered characteristic in which horizontal stratification planes can be distinguished, because natural porous medium may have been created through a sedimentation process, which makes the permeability of porous medium different in horizontal and vertical directions. Since, for most engineering practices, a multilayered porous medium is a general case, a five-layered porous medium with anisotropic permeability and compressible constituents under a uniform square load is investigated to study the influence of layered characteristics of porous medium on the consolidation behavior. First, the influence of layered characteristic of shear modulus on the surface settlement is studied.
