    Abstract
  • Because of the problems of low accuracy, insufficient application effect and inability to realize automation in the monitoring of underground pipeline leakage and road voids by conventional detection methods, distributed optical fiber vibration sensing technology is proposed to monitor underground pipe networks and road diseases. A technology method for real-time intelligent monitoring of underground pipe network operation and maintenance status and changes of road subgrade and surrounding soil diseases is developed. Through the test verification, the signal and background noise automatically collected by the front-end optical fiber equipment were analyzed, and the monitoring efficiency and accuracy of the underground pipe network and road disease were improved. The results show that the overall recognition rate of this method for underground pipeline leakage and road diseases is over 90%, meeting the needs of underground pipeline networks and road maintenance and accident prevention.
