为了对在役阶段的桥梁进行挠度监测，基于桥梁的结构特点，用光纤光栅静力水准仪对主梁进行挠度监测，用数理统计的方法对主梁挠度进行健康分析。监测结果得出主梁挠度在规范的范围以内，桥梁的健康状况良好。光纤光栅静力水准仪性能稳定，精度高，在挠度监测方面具有广阔的应用前景。%For Monitoring the bridges in the usage stages,Based on the characteristics of bridges, useing fiber grating Static Force Level to monitor the Deflection of main girder,and mathematical statis-tics to do the Health Analysis.The results showed that the data was within a reasonable range of the code, and is in good health.The Fiber Grating Static Force Level has stable performance and high precision,and broad applying prospect in this respect of monitor the deflection of bridges.
