基于Fredlund和Hasan的固结理论,研究了非饱和多层地基的一维固结问题,并在假定固结过程中各材料参数保持不变的条件下,得到了典型边界条件下的解析解。在解析解的推导中,首先利用传递矩阵法推导出多层问题的本征函数和本征值。然后,利用待定系数法和本征函数的正交关系,得到了该问题的解析解。本方法适用于各种类型的边界条件。最后通过数值算例分析了非饱和多层地基的固结特性。
The 1D consolidation of unsaturated multi-layered soil is studied based on the theory proposed by Fredlund and Hasan, and an analytical solution for a typical boundary condition is obtained by assuming all material parameters remain constant during consolidation. In the derivation of the analytical solution, the eigenfunction and eigenvalue for the multi-layered problem are first derived through the transfer matrix method. Then, by using the method of undetermined coefficients and the orthogonal relation of the eigenfunction, the analytical solution is obtained. The present method is applicable to various types of boundary conditions. Finally, numerical examples are provided to investigate the consolidation behavior of unsaturated multi-layered soil.
