| Abstract: | Rubber bearing aging and damage is a common disease during bridge operation. The bearing replacement usually need stop transportation long time which block traffic. The paper takes the engineering practice as examples and replaces a bearing of T shape simply supported girder of the bridge with 20m span. It adopts jack method,and obtains good engineering result. |
