| 摘 要： | 由基桩静载试验数据建立目标函数，用非线性最小二乘法求解该目标函数的极小值，从而得到基桩极限荷载值。这一方法不仅可用于对单桩极限荷载的精确确定，也可用于对单桩极限荷载的预测，计算实例表明，该方法是很有效的，具有较大的实用价值。 |

| Abstract: | Based on the data from observation of the pile loading test,an objective function was established.Non-linear least square method was used to solve the minimum value of the objective function and further to obtain ultimate pile load.The method can be used not only to calculate the ultimate pile load but also to predict the ultimate pile load.The calculating results of observed data demonstrate that the method is very effective. |
| Keywords: | pile loading test ultimate pile load non-linear least square method prediction |
