THE SERIES SOLUTION OF BIOT CONSOLIDATION OF SPHERICAL SOIL-SAMPLE AND MANDEL-CRYER EFFECT

The Biot consolidation of spherical soil-sample is one of the famous examples in discovering the Mandel-Cryer effect. In this paper the solution of the Biot consolidation of the spherical soil-sample is decomposed into the elastostatic solution and quasi-dynamic solution of fluids in porous media. By means of the orthogonality of spherical Bessel functions, a close form series solution of the problem is presented and quantitative analysis is conducted. The Mandel-Cryer effect is discussed at length.
