| 摘 要： | 静压桩优点众多,但沉桩带来的挤土效应也十分明显。采用应力释放孔法能有效地减少沉桩带来的对周边环境的影响。通过借助FLAC3D有限元软件,采用分段压入的方式对单桩沉桩过程进行了模拟,得出了不同桩长时孔深和孔径的最佳组合,从而对实际的工程施工提供一定的参考。

| Abstract: | Jacked pile has many advantages in engineering practice.But the compaction effect caused by jacked pile singking cannot be neglected.The hole to release stresses may reduce the unfavorable influence on the environment while jacked pile sinking.With the FLAC3D,this paper look on the process of driving pile as crushing soil step by step and simulates the pile driving,then concludes with the best combination of the depth and diameter of the hole,which will offer some reference for engineering practice. |
