摘要: 光纤光栅传感器性能优良,适合土木工程应变的长期测量。对光纤光栅传感器用于土木工程监测的布设工艺等相关问题进行了研究,并在江苏省邮政通信指挥中心工程成功地使用光纤光栅传感器对施工中结构受力体系转换过程进行了监控。结果表明,光纤光栅传感器测量数据稳定可靠,并且能进行分布式测量,效果明显优于传统的应变计。Abstract: Fiber bragg grating ( FBG ) sensor is a promising measurement technology for strain monitoring in civil engineering. Techniques of installation for FBGs have been explored, and it has been successfully used in construction monitoring of Jiangsu Post Mansion. The monitoring result shows that FBGs are very stable and reliable, and can be used to form distribution measurement systems. So FBG strain sensor is more superior to the conventional strain gauge.
