    Abstract
  • In view of problem of low monitoring efficiency, poor authenticity and accuracy of surrounding rock stress monitoring, a surrounding rock stress monitoring system which can realize real-time online monitoring and long-term monitoring was proposed according to sensor principle and mechanical characteristics of fiber grating. The system applies fiber grating sensing technology to real-time monitoring of surrounding rock stress, and has advantages of high precision, small error and strong anti-interference ability.
