桥墩顶推纠偏技术在连续梁桥中的运用

The Application of Pier-Top Pushing and Rectifying Technology in Continuous Beam Bridge

结合某工程实例,依托数值分析结果和现场施工监控数据,对连续梁桥桥墩顶推纠偏过程中,墩体的受力和变形进行了对比分析,同时,提出了顶推施工中的一些质量措施和技术要点。通过分析对比可知,采用此类顶推施工技术,不仅可以保证桥梁的施工质量,还可以大幅节约劳动力与设备。

Combined with an engineering example,based on the numerical analysis results and on-site construction monitoring data,the stress and deformation of the pier body during the deviation correction process of the pier-top of continuous beam bridge are compared and analyzed,at the same time,it also puts forward some quality measures and technical points in pushing and correcting the bridge piers.Through analysis and comparison,it can be seen that the adoption of such jacking construction technology can not only ensure the construction quality of the bridge,but also greatly save labor and equipment.
