Abstract
Based on the solutions of the Green’s function for a saturated porous medium obtained by the authors and using transformation of axisymmetric coordinates Sommerfeld integrals and superposition of the influence field on a free surface the authors have obtained displacement solutions of a saturated porous medium subjected to a torsional force in a halfspace The relationship curves of the displacement solutions and various parameters permeability frequency etc under action of a unit of torque are also given in this paper The results are consistent with previous Reissner’s solutions where a twophase medium decays to a singlephase medium The solution is useful in solving relevant dynamic problems of a twophase saturated medium in engineering
