| 摘 要： | 结合江阴长江公路大桥结构健康监测系统升级改造项目,采用拉绳式位移传感器实时监测大桥主梁的纵向运动,并依据实测数据进行梁端位移变化和运动同步性的统计分析。结合突发船撞事件,采集撞击下的大桥位移响应和结构激励状态信息,评价大桥受撞击后的结构损伤和工作性能,得出结论认为此次撞击对主梁的损伤较小,并且大桥运营近6年来主桥钢箱梁结构的刚度并没有发生明显劣化。 |
| 关 键 词： | 拉绳式位移传感器 在线实时监测 结构健康评估 |

| Abstract: | Based on the improvement project of structure assessment and monitoring system for Jiangyin Yangtze River Bridge,the displacement of the main girder and synchronization of the movements are presented.As caused by ship impact accident,the displacement response and the excited status of the bridge were collected to evaluate the damage of the structure.The research results show that the impact has small influence on the structure and the structural rigidness of the main girder has no obvious deterioration after six-year services. |
| Keywords: | draw-wire displacement sensor real-time monitoring structure health assessment |
