Consolidation is one of the fundamental topics of soil mechanics. Researches have been mainly focused on the plane consolidation and axisymmetric consolidation. The study on consolidation of saturated soil under non-axisymmetric load has seldom been reported. By using Fourier expansion, Laplace transform and Hankel transform, the Biot's consolidation equations of saturated soil are solved in this paper. On the base, the non-axisymmetric consolidation of half-space saturated soil is discussed. The expressions of soil skeleton displacement and porous water pressure are given. With the aid of numerical calculation, these formulae could be used to analyze the characteristics of non-axisymmetric consolidation of saturated soil.
