摘要：

This research focuses on quantitative analysis of elastic space waves propagating porous media saturated with fluid. Compressive wave propagations are described in three dimensional (3-D) spherical coordinates in terms of displacements of the fluid and solid of the porous media. The wave superposition properties under multiple energy resources are investigated. Relative displacements between the fluid and solid of a porous medium in 3-D domain are quantified with consideration of the wave propagations excited by multiple point energy sources. Numerical analyses are performed and practically sound results are obtained.
