Abstract

Abstract

Based on Biot's dynamic consolidation equations,by means of Laplace_Hankel transform technology,the integral solutions of stress and displacement in saturated soil with subjacent rock_stratum under axisymmetric arbitrary excitations were derived.Influence of the reflected wave generated by the boundary was revealed.Numerical results indicate that the vibration frequency has some effect on the vertical displacement of saturated soil.The vertical displacement at the surface of saturated soil lags in phase with the load.Furthermore,the dynamic permeability coefficient of saturated soil has significant effect on the vertical displacement at the initial stage of load applied,but when the load becomes stable,the effect is inapparent.
