CHEN Shu-li1,2 ,SU Mu-biao1,2,SUN Bao-chen1,2 FENG Xiao-li3(1 Structural Health Monitoring and Control Institute, Shijiazhuang Railway Institute,Shijiazhuang; 2 The Key Laboratory of Structural Health Monitoring and Control of Hebei Province,Shijia- zhuang;3North University Garden SiFang School, Shijiazhuang Railway Institute ,Shijiazhuang)  
As a kind of new-style sensor test technology that has the most popular outlook and the most fitness in long-term health monitoring, the optical fiber sense test technology has got a comprehensive application overseas, and the optical strain sensor is welcomed by engineering field all over the world. This paper briefs the importance of strain monitoring in bridge structure health monitoring.Advanced optical strain sensors are cheese for strain monitoring in Wuhu Changjiang river bridge, the trigger pattern of monitoring is determined, and a set of software is developed in this paper. The achievement provide profitable experience for popularizing optical strain sensor in strain monitoring in the future.
