摘　　要：针对我国铁路桥梁检定相关规范现状,提出了双柱式桥墩运营性能评判依据。以某重载铁路特大桥双柱式桥墩为例,介绍了其加固方案比选情况,阐述了其运营性能试验测点布置、测试工况;分析了加固前、加固后的跨中横向振幅及墩顶横向振幅等实测数据。试验结果表明,所采取的加固方案的加固效果十分明显,能满足该铁路目前的重载运输需求。In light of domestic railway detection norms, the paper puts forward double-column-style pier operation evaluation basis. Taking thedouble-column pier of the extra-large bridge of the heavy-load railway as an example, it introduces its reinforcement scheme comparison conditions, describes its operation performance testing points arrangement and testing conditions, analyzes mid-span horizontal amplitude and pier tophorizontal amplitude and other actual testing data before and aftr the reinforcement. The experimental results show that ： the reinforcement effect ofthe adopted reinforcement scheme is very obvious, which can meet current heavy-load railway transportation demands.
