A multi-pile reinforced soil layer is assumed to be composed of two solid composite. The fundamental dynamic properties and wave propagation characteristics of the mixture ground with complex configuration is given by applying the two phase medium mechanics. Theory is presented by averaging the physical quantities such as displacements, stresses and density. The characteristic behavior of pile reinforced ground as two solid medium is explained in terms of the difference of the relative displacements between two average solid ones-pile and soil. The dispersion due to geometrical configuration of pile ground is given and considerable in comparatively low frequency range. The wave transfer properties is numerically analysed and the coupling terms interacted between two solid interfaces are discussed.
