| 中文摘要: |
| 橡胶支座损坏是装配式连续箱梁桥的通病，橡胶支座质量问题和支座受力不均及偏心受压是导致支座发生病害的直接原因，结合京沪高速公路淮安某特大桥的支座检查，分析了生产、设计、施工对支座病害的具体影响，提出了相应建议，并对支座质量控制进行了探讨。 |
| 英文摘要: |
| Rubber bearing damage is a common fault in fabricated prestressed concrete continuous box girder, the causes leading to the damage are related to rubber bearing quality, non-uniform load and eccentric compression.Combined with bearing examination in a large bridge of Jinghu expressway,this paper analyzes the effect of production, design and construction of bearing to the damage and the quality control of bearing,the corresponding measures are thereby proposed. |
