%X Based on relevant assumptions,several governing equations are derived and the equation of saturated liquefaction in granular media is educed. The potential vector equation and the velocity expression of three kinds of body waves under the conditions of no dissipation,as well as the general equation of potential vector and the attenuation coefficients of P wave and S wave under the conditions of dissipation are deduced. By the vibrating liquefaction experiment of tailings and fine iron ores,the change of pore water pressure is observed and noted when the vibrating liquefaction takes place. With the infliction of vibration,the pore water pressure is increased with wave motion. Using the wave theory and experimental results,the influence of three body waves is analyzed in details on pore water pressure,and the mechanism of pore water pressure and the wave mechanism of vibrating liquefaction are revealed.
