摘　　要：随着城市的飞速发展,其交通量也与日俱增,许多桥梁开始出现各种各样的病害。其中,桥梁的支座病害是较为常见的一种。当支座出现病害后,会对桥梁整体的耐久性、安全性产生决定性影响,因此,衍生出支座更换这一桥梁病害处理工艺。文章以厦门大桥改造加固项目支座更换工程为例,详细介绍了减隔震球型钢支座更换的特点、原理及施工过程,可为今后类似的超长跨海连续梁桥改造加固项目提供重要的参考价值。With the rapid development of cities,their traffic volume is also increasing day by day,and many bridges are beginning to suffer from various diseases.Among them,the bearing disease of bridges is a relatively common type.When the bearing is damaged,it will have a decisive impact on the overall durability and safety of the bridge,thus deriving the bearing replacement as a bridge disease treatment process.The article takes the support replacement project of the Xiamen Bridge renovation and reinforcement project as an example,and provides a detailed introduction to the characteristics,principles,and construction process of the replacement of seismic isolation spherical steel bearings.This can provide important reference value for similar projects of the renovation and reinforcement of super long sea crossing continuous beam bridges in the future.
