| 摘 要： | 利用Poulos弹性理论法，对锚桩法单桩静载承载力试验中试桩和锚桩之间的相互作用进行了研究，提出了考虑锚桩上拔量对试桩p-s曲线影响的方法。利用该方法对某工程实测资料进行了分析，发现采用原始测试数据分析所得出的试桩极限承载力偏于危险，并为该工程提供了更加合理的单桩极限承载力值。

| Abstract: | The interaction between loading pile and anchor-piles in the anchor-pile loading test is studied. A method which based on the Poulos elastic theory to take account of the influences of the interaction on the P~s curves of the loading pile, is presented. Then, the data of a test have been analyzed using this method. The conclusion is that the result from the original data analysis is larger than its actual bearing capacity. |

| Keywords: | anchor-pile loading test elastic theory method bearing capacity of single pile interaction of pile group |
