| 摘 要： | 采用Biot固结方程和修正的考马拉—黄模型相耦合的分析方法,对荷载作用下的单桩进行了分析。用Biot固结理论模拟土体固结,以修正的考马拉—黄模型模拟土体流变,全面呈现了单桩受荷变形的全过程。通过分析荷载作用下土体内孔压增长和消散、沉降变形、桩侧摩阻力等随时间的变化,得出了一些有益的结论。

| Abstract: | In this paper,the coupled methods of Biot consolidation theory and the modified Kommala-huang model are employed to perform a theoretical analysis of a pile-raft foundation.Given that the Biot consolidation theory simulates soil consolidation,and the modified Komamura-Huang model simulates soil rheology,it allows the deformation process of pile-raft foundation under longtime loads to be fully presented.Some useful conclusions are drawn from an analysis of soil pore pressure increasing and dissipating,of settlement,and of a pile profile frictional resistance's variation with time. |
