摘要
为研究连续梁桥非连续墩墩顶向上坡方向偏移这一现象,文中以辽宁境内某大桥为工程背景,从病害成因机理、影响因素和产生条件进行分析,提出了相应的病害处理方法和预防性对策,后期实施效果良好。可为类似工程的设计、施工质量控制及加固维修提供参考。
Upward deviation as the hazard exists within the top of discontinuous piers of continuous beam bridge.Taking a bridge in Liaoning as the case, the causes, influencing factors, and producing conditions of the hazard are analyzed, and the corresponding treatments and preventive countermeasures are proposed with good implementation effect during the later stage. It may provide reference for the design, construction quality control, and reinforcement maintenance of similar projects.
