摘要
文中以某高速公路的一座高墩装配式连续T梁桥为研究背景,对已运营桥梁出现桥墩偏位情况下的病害情况和成因进行了全面分析,并采用竖向顶升和水平顶推施工工艺进行纠偏复位,对纠偏施工过程中的竖向顶升和水平顶推过程的结构安全性进行了验算,为同类桥梁的养护维修决策提供科学合理的技术参考和依据。
This paper makes a comprehensive analysis of the diseases and causes of piers deviation in existing bridges,taking a high-pier fabricated continuous T-beam bridge on a highway as the research background.The vertical jacking and horizontal jacking were used to correct the deviation,and the structural stability of the vertical jacking and horizontal jacking were checked.This paper provides scientific and reasonable technical reference and basis for the maintenance decision of similar bridges.
