柔性基础下复合地基的数值分析

Numerical analysis of the composite ground under the flexible foundation

运用 MARC软件 ,对柔性基础下复合地基的受力与变形性状进行了弹塑性有限元分析 ,探讨了地基土体、桩体及上部荷载各参数对复合地基性状的影响 ,并与室内模型试验结果进行比较 ,找出了影响柔性基础下复合地基受力与变形性状的因素及其影响程度。

Using the MARC software, authors analyze the property of the mechanics and deformation of the composite ground under the flexible foundation with the finite element method, argue the influences resulted by the parameters of the ground, the pile and the upper load to composite ground, compare the calculated results with the model experiment results, find out the factors and the rules influencing the properties of the composite ground under the flexible foundation.
