在桥梁结构中，支座是上、下部结构的连接点，其作用重大，但由于年久失养或橡胶支座本身老化、钢板支座锈蚀失效等问题，有些已直接影响到桥梁上部结构安全，需要在不破坏桥梁本身结构的情况下来对支座进行整体更换，使之恢复原有功能，以保证桥梁整体运行安全。对在桥梁支座整体更换工作中所采用的主要施工方法和措施作了简要介绍。

Probe into the Integrated Replacement of the Bridge Supporting Stands

In the structure of the bridge, the supporting stand, which is the connecting point between the upper and under structures, has important functions. But because of having long been cut of repair or the aging of the supporting stand itself, and the rust-eaten and inactivation of the steel-plate supporting stand, some problems have directly influence the safety of the upper structure of the bridge, it is urgent to make integrated replacement for the supporting stands under the condition of no damaging the structure of the bridge itself for recovering the original functions of the bridge and guaranteeing the safety in operation of the whole bridge. This paper introduces briefly the main construction methods and measures adopted in the integrated replacement of the bridge supporting stands.
