| 中文摘要: |
| 本文通过小模型试验并借助大型有限元分析软件MARC对微群桩地基模型沉降特性进行数值模拟，找出了复合地基的位移场和应力场的一些基本规律，计算结果表明，微桩加固地基对减少沉降起到了显著作用。在此基础上，利用MARC程序对天然地基和微群桩复合地基进行地震动力时程分析，得到桩的加入有利于地基抗震的结论，为微群桩复合地基工程设计应用提供了依据。 |
| 英文摘要: |
| The decline of micro piles reinforced foundation was studied in model test and numerically simulated by using the software MARC of FEM. The results show that the micro piles can remarkably reinforce the foundation and reduce the decline. On this basis, the MARC program is applied to analyze the temporal dynamic characteristics of pure soil foundation and micro-piles reinforced foundation. The comparison shows that the micro piles are effective in elevating the earthquake resistance of foundation. |
