| Abstract: | By taking the large buried pressure water conveyance pipeline of a water source project in Shenzhen as a case， a prototype test is made on the pipeline with the Φ-OTDR fiber interferometer principle-based vibration monitoring method. Through simulating the leakage from pipeline burst with emptying valve， the monitoring effect of the distributed optical fiber is tested in combination with knocking test. The test result shows that it is feasible to apply the distributed optical fiber to the continuous monitoring of the buried pressure water conveyance pipeline. |
