| 中文摘要: |
| 深水环境下的桩基础长期承受潮位的涨跌产生的低频循环荷载,从而增大了桩基础的工后沉降.室内模型试验结果表明,在低频循环荷载作用下,地基土逐渐被压密,从而产生硬化,但硬化的程度无法通过试验进行定量评价.利用ABAQUS有限元软件开展数值模拟,定量评价地基土硬化对桩基础承载性能的影响. |
| 英文摘要: |
| Pile foundation longly bears low-frequency cyclic caused by loading tidal level in deep-water environment,thus causing the post-construction settlement increasing of pile foundation. The research result of indoor model tests indicates that foundation soil is pressed consolidation gradually,and leads to be hardened. However,hardeneing degree can’t be evaluated quantitatively by tests. The paper develop numerical simulation using ABAQUS finite element software to quantitatively evaluate the effect of foundation soil hardening on bearing behavior of pile foundation. |
