Abstract

A new analytical method is presented to study the axis-symmetric Biot's consolidation of a finite soil layer.Starting from the governing equations of axis-symmetric Biot's consolidation,and based on the property of the Laplace transform,the relationship of basic variables for a point of a finite soil layer was established between the ground surface(z=0) and the depth z in the Laplace and Hankel transform domain.Combined with the boundary conditions of the finite soil layer,the analytical solution of any point in the transform domain can be obtained.The actual solution in the physical domain can be acquired by inverting the Laplace and the Hankel transforms.The numerical analysis for the axis-symmetric consolidation of a finite soil layer was carried out by program.
