This paper presents the numerical investigation of Biot theory on acoustic wave propagation in fluid saturated porous media. The effects of porosity, permeability, fluid viscosity and pore size of porous media on the velocity and attenuation of three kinds of bulk waves are calculated when the frequency is equal to 80Hz, 20kHz, and 500kHz respsctively. Some calculation results arc in agreenment with laboratory and field measurements.The present study contributes to a better understanding and application of Biot theory.
