摘　　要：某公路桥梁在运营阶段出现了墩柱偏位、支座损坏等病害,通过桥梁结构特征分析及病害现状研究,确定了梁底支撑面不水平是造成公路桥梁在运营阶段出现墩柱偏位现象的主要原因。制定了墩柱纠偏复位、更换新型球型支座以及墩柱加固等综合维修处治措施,结果表明:这些维修处治措施可以明显改善墩柱偏位现象,可阻止病害进一步发展,恢复桥梁的正常使用状态。A highway bridge has some diseases such as pier column deviation,bearing damage and etc.in the operation stage.Through the analysis of bridge structural characteristics and the research on the disease status,it is determined that the non-level support surface at the bottom of the beam is the main reason for the pier column deviation of the highway bridge in the operation stage.The comprehensive maintenance and treatment measures such as pier column deviation correction and restoration,new spherical bearing replacement and pier column reinforcement are formulated.The results show that:these maintenance and treatment measures can significantly improve the pier column deviation,prevent the further development of the disease and restore the normal service state of the bridge.
