| 摘 要： | 采用高应变法确定预制桩承载力时，通过拟合得到的承载力具有多解性。因此提出了拟合参数的选取不一定要限定在规定的范围内，同时还
要根据预制桩设计参数、施工工艺或土体工程性质来选取拟合参数，解读高应变曲线，这样才能得到符合实际情况的预制桩承载力。 |
| 关 键 词： | 高应变法 极限承载力 预制桩 波动方程拟合法 |

| Abstract: | The bearing capacity of the prefabricated pile obtained by the high strain method is not entirely correct. In obtaining accurate bearing capacity, fitting parameters are not necessarily confined in the provided range. The high strain curve should be explained on the basis of the fitting parameters determined by such factors as the parameters of the prefabricated pile, the construction technology and the engineering properties of soil. Only in this way can real bearing capacity be obtained. |
| Keywords: | high strain method ultimate bearing capacity prefabricated pile CAPWAP |
