摘要
基于有限元法建立复合地基三维固结过程的动力学模型.该模型包括桩-土相互作用、土壤-孔隙流体材料等的非线性特性.通过子模型和嵌入区域技术,降低计算规模,提高计算模型的收敛性,并建立针对此类问题的基本分析流程和方法.
The dynamics model of consolidation process of composite foundation is built based on finite element method. The model includes some non linear characteristics, such as pile soil interaction, soil pore fluid material and so on. By the submodel and embedded region technology, the calculation region is reduced and the convergence of the model is improved. The basic analysis processes and methods are built for the problem.
