摘　　要：以深圳某水源工程大型埋地压力输水管道为例,应用基于Φ-OTDR光纤干涉原理的振动监测方法,对管道进行原型观测试验。通过运用放空阀模拟爆管泄漏事件,并结合敲击试验,检验分布式光纤的监测效果。试验结果表明,分布式光纤用于埋地压力输水管道泄漏连续监测是可行的。By taking the large buried pressure water conveyance pipeline of a water source project in Shenzhen as a case, a proto- type test is made on the pipeline with the ~P - 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 mo- nitoring of the buried pressure water conveyance pipeline.
