摘　　要：随着城市化进程的不断加快,轨道交通桥梁作为公共交通的重要基础设施,发挥了越来越重要的作用。然而,由于长期使用和各种外力的作用,轨道交通桥梁的支座易产生多种病害,如支座开裂、吊空、变形等。现分析轨道交通桥梁支座病害的种类和表现形式,提出针对各种病害的具体处理措施。这些病害包括橡胶支座老化、裂缝、外翻、吊空,以及支承垫石开裂等问题。同时,根据实际工程案例,总结并提出了轨道交通桥梁支座病害的预防措施和维护管理策略,旨在为轨道交通桥梁的安全运行和使用提供参考和指导。With the continuous acceleration of urbanization,rail transit bridges,as important infrastructure for public transportation,have played an increasingly important role.However,due to long-term use and various external forces,the bearings of rail transit bridges are prone to various diseases,such as bearing cracking,suspension,deformation,etc.This paper analyzes the types and manifestations of these defects,and propose specific treatment measures for various defects.These defects include aging of rubber bearings,cracks,outward flipping,hanging,and cracking of bearing pads.At the same time,based on actual engineering cases,preventive measures and maintenance management strategies for bearing diseases of rail transit bridges were summarized and proposed,aiming to provide reference and guidance for the safe operation and use of rail transit bridges.
