| Abstract: | Contraposed to the disadvantage of anchor monitoring, a novel fiber optic Bragg pre-stress sensor is adopted in this paper,based on the analysis of the using pre-stress sensors. At the same time, the principle and constitutes of novel system are presented in detail. With the compared experiment of the FBG senor and the common electricity sensor stuck on the applied site, the result show that the FBG sensors have a high measurement precision lever, good anti-interference ability and long-term stability, simple structure and it can realize a real-time and on-line monitoring. |
