| 摘 要： | 桶形基础受负压作用下沉时,基础与地基土体之间产生相互作用.为了合理地模拟2种不同材料之间的相互作用,将有限元、无限元、接触单元耦合的数值计算方法引入到桶形基础与土壤相互作用的强度分析中,并将用该方法得到的计算结果与模型试验比较.其中,接触单元考虑结构与土壤之间的错动滑移及拉裂;而无限元可有效地反映地基土体无限域的远场效应.

| Abstract: | The interaction between the bucket foundation and foundation soil will occur during the bucket foundation suction penetration. In order to properly simulate the interaction between two kinds of material, the numerical computation method of coupling finite infinite interface element is applied to the strength analysis of above interaction, and the comparison between the numerical computation results and the model test results is made. Among them, the interface element is used to think of the interface slippage and ripping, and the infinite element is used to reflect the remote effect of infinite foundation soil field. |
