Abstract: The Biot consolidation of spherical soil samples is oneof the famous examples in showing the Mandel-Cryer effect. For thisfamous example, there is a series solution consists of anelastical solution which satisfies the inhomogeneous boundary conditions and aquasi-dynamic solution of fluids in porous media which satisfies thehomogeneous boundary conditions. And through numerical analyses, some Biotconsolidation characters and even factors to the Mandel-Cryer effect of spherical soil samples are investigated.
