| 摘 要： | 双曲线法能够比较好地预测P-s曲线为缓变型的桩基的极限承载力。根据7根挤扩支盘桩的实测P-s曲线，用双曲线法预测了支盘桩的极限承载力。结果表明在极限加载范围内，双曲线法同样适用于挤扩支盘桩，拟合双曲线与实测的曲线比较吻合，预测的结果对工程实际有一定的价值。

| Abstract: | Hyperbola method can be used to predict the ultimate bearing capacity of pile, of which P-s curve is an adjustment curve. The ultimate bearing capacity of squeezed branch pile is predicted based on seven piles from two different sites by hyperbola method. The results indicate that the predicted curve is agree well with the field measurement curve below ultimate load; the hyperbola method is also suitable for squeezed branch pile; and the predicted results can be used in practice. |

| Keywords: | hyperbola method squeezed branch pile ultimate bearing capacity |
