    Abstract
  • Accurate monitoring of the deformation of the deep surrounding rock of the tunnel can improve the efficiency and safety during tunnel construction. Weak grating technology was used to monitor the deformation of the deep surrounding rock of a water conveyance tunnel in Pingyang. The monitoring results show that the strain change of tunnel surrounding rock is small, and the stability of surrounding rock is generally good. The monitoring results of the weak fiber grating sensing cable is basically consistent with the traditional monitoring results, which are in line with the facts. The monitoring plan and monitoring results can provide reference for similar projects.
