强夯法加固饱和软粘土地基数值模拟

Numerical Simulation of Saturated Soft Clay Ground Improvement by DCM

本文主要介绍基于Boit固结理论以数值法模拟强夯加固饱和软粘土地基过程的方法。程序中考虑了土体的非线性及孔隙水的紊流特性 ,且对重要参数E和K采用反演法进行动态跟踪。文中应用该程序对某机场地基处理工程进行了数值分析 ,结果比较合理 ,为强夯法数值分析提出了一个可行的思路。

In this paper the numerical method based on Boit's consolidation theory to simulate the process of saturated soft clay ground improvement by dynamic consolidation method (DCM) is introduced. The nonlinear characteristic of soil as well as turbulent characteristic of pore water was considered in the program and the important parameters E and k were tracked dynamically by the reverse deduced method. Some aerodrome's soil improvement projects were analyzed numerically with this program and the results were rather reasonable. So a feasible way for numerical analysis of dynamic consolidation method was offered.
