| 摘 要： | 根据桥墩桩基施工现场的具体情况，通过理论计算，分析了两基桩产生偏位的主要原因。采用卸载止推、反向堆载、挖坑卸荷、强力牵拉等综合纠偏方法对产生偏位的两基桩实施纠偏，经过一个多月的缓慢纠偏使两桩基基本恢复原位，纠偏后经桩身低应变动测（反射波法）检测其桩身完整满足设计要求。

| Abstract: | The main causes for the deviation of two bridge piles were analyzed by theoretical analysis, taking into consideration of the actual conditions of the construction site of the bridge piles. The deviation of the two piles was corrected with integrative correction methods, including unloading stoppage, reverse heap-loading, unloading by digging holes(pits), and forced pooling. With over one month's gradual correction, the two piles'positions were basically restored. The examination of the piles with low strain dynamic measurement reflective wave showed that the piles were complete and met the design demand. |
