摘　　要：公路桥梁在建设及运营阶段有时会发生墩柱偏位,该病害严重影响了桥梁结构的安全。以某山区高速公路桥梁为研究对象,依据相关规范和桥梁病害检测结果,分析了桥梁产生墩柱偏位的原因。通过理论计算,验证该桥梁结构承载能力并未降低,但结合工程实际情况从延长桥梁结构使用寿命的角度出发,需对桥梁墩柱偏位采取相应的处治措施,据此提出了桥梁墩柱偏位的纠偏处治方案。The deviation of pier column often occurs in the construction and operation stage of highway bridges,which seriously affects the safety of bridge structure. Taking a highway bridge in a mountainous area as the research object, the causes of pier column deviation of the bridge are analyzed according to the relevant specifications and bridge disease detection results. Through theoretical calculation,it is verified that the bearing capacity of the bridge structure has not been reduced. In combination with the actual situation of the project,but from the perspective of prolonging the service life of the bridge structure,it is necessary to take the corresponding treatment measures for the deviation of the bridge pier column. Based on this,the correction and treatment scheme for the deviation of the bridge pier column are put forward.
