Analytical method for spherical waves propagation in saturated soils

In present paper, the generally-adopted saturated soil model in engineering is adopted for analyzing the spherical waves propagation in saturated and elastic soils. The analytic solution in transformed domain is got by the method of Laplace transformation, and numerical results are presented through Laplace inversion. The displacements, stresses and pore water pressure are investigated during the waves propagation and compared with the spherical waves propagation in elastic and single-phase medium, and some features of the problem are revealed. The study is reasonable for engineering practice and provides an effective method for analyzing the similar problem about spherical waves propagation.
