Abstract: Based on Biot equations governing the behavior of saturated linear elastic porous soil under dynamic loads, by the method of integral transform and matrix transfer,two-dimensional consolidation of saturated soils is studied. Then, the general integral solutions of stress (including pore pressure) and displacement (including fluid flow)were obtained under harmonic vibration load according to impermeable boundary condition. Finally,the influence induced by variation of dynamic coefficient of permeability on soil displacement and stress under harmonic vibration load is investigated.
