金湾大道高架桥墩柱偏位分析与纠偏处理

摘要

由于不平衡土压力过大、地质情况复杂特别是软土、淤泥等软弱土质覆盖较厚等原因,桥梁桩基和墩柱偏位现象时有发生. 因此,为保证结构安全和工期,桩基和墩柱偏位后的纠偏处置非常重要. 以珠海市金湾大道高架桥右幅19 #、20 #墩柱纠偏处理为例,对其墩柱偏位原因进行分析,并采用应力释放及强制恢复等方法对偏位桥墩实施纠偏,获得较好效果.%For excessive unbalanced soil, complicated geological conditions, in particular thick coverage of weak soil such as soft soil and sludge, etc. , offset of bridge pile foundation and piers happens from time to time. Therefore, in order to guarantee safety of structures and construction period, rectification after offset of pile foundation and piers is very important. With rectification of offset of right No. 19 and No. 20 piers of Jinwan Road viaduct as an example, this paper analyzes reasons for offset of piers and adopts the methods of stress releases and forcible recovery, etc. to rectify offset piers and obtains good effect.
