| 摘 要： | 以抗拔桩变形的理论分析为基础,选择双曲线荷载传递函数对桩的极限侧阻力进行合理取值,通过迭代法得到桩身受力情况,由此预测抗拔桩的＂有效桩长＂。结合工程实例进行了计算验证,证明该方法具有实用价值和推广意义。

| Abstract: | Based on theoretical analysis of uplift pile deformation,stress state of pile is obtained by iteration with the hyperbolic load transfer function and reasonable value of the ultimate side resistance of piles,thus the effective length of uplift piles can be predicted and verified by engineering example. |
