| 摘 要： | 根据荷载传递理论,提出了一个计算抗拔单桩位移的十分有效的迭代算法及预测抗拔群桩变形的简化分析方法.根据等效墩原理,将抗拔群桩基础简化为单一的墩基础,从而可以将单桩变形研究成果应用于群桩变形分析中.通过与现场试验结果进行比较表明,该方法不但可以大大节省抗拔群桩变形的计算时间,而且计算结果与实测结果也较为相符. |

| Abstract: | A highly effective iterative procedure is developed to examine the load-displacement behaviour of a single tension pile by load transfer theory. Moreover an approximation method that can for predicting deformations of tension pile groups is given. The method assumes pile groups as an equivalent pier so that the analysis method of single pile can be used for pile groups. Compared with field experiment, the equivalent pier method not only can save a large amount of computing time but also give reasonable results. |
| Keywords: | pile group equivalent pier deformation |
