| 摘 要： | 固结问题是土力学的基础课题之一，现有的研究主要针对饱和土的平面固结和轴对称固结问题。本文应用Fourier展开、Laplace变换和Hankel变换求解了各向同性饱和土的Blot固结方程；讨论了半空间各向同性饱和土的非轴对称固结。借助数值计算，本文的方法可以用于分析各向同性饱和土的非轴对称固结问题。 |

| Abstract: | 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. |
