摘　　要：光纤传感测试技术作为未来最有前途、最适合长期健康监测的一种新型传感测试技术 ,在国外已经得到了比较广泛的应用 ,而光纤应变传感器更是受到了世界各国工程界的普遍欢迎。本文主要介绍国内首次大量采用光纤应变传感器对吴忠黄河大桥进行施工阶段应力监测中的应用情况 。The optical fiber sensor technology regarded as one of important functional and healthy long term monitoring of sensor testing technologies has been used widely in the foreign countries.The optical strain sensor is more welcome in the engineering field worldwide. The results of optical fiber strain sensor used for the stress monitoring during the construction of Yellow River Bridge in Wuzhong County are mainly introduced in this paper. It aims to provide beneficial experiences for the application of optical fiber strain sensor in the stress monitoring in later days.
