摘　　要：国内某调水工程的玻璃钢夹砂管(RPMP)出现多次爆管,为此开展了压力输水管道渗漏连续监测技术与爆管预警系统的研究。研究表明:采用基于-OTDR原理的分布式振动光纤监测系统和准分布式光纤光栅压力传感系统能够对埋地压力管道进行泄漏连续监测和泄漏点的定位,起到爆管预警作用。所得成果为压力管道爆管预警的研究提供参考。Pipeline burst occurs for many times on the pipeline consisted of glass fiber reinforced plastics mortar pipes（RPMP） of a water diversion project in China, and then a study on the continuous monitoring technique for the leakage of pressure water conveyance pipeline and the early warning system for pipeline burst is carried out. The study shows that the continuous monito- ring of leakage and positioning of leakage point can be made on the buried pressure pipeline by both the φ - OTDR principle based distributed vibration optical fiber monitoring system and the quasi-distributed optical fiber grating pressure sensing sys- tem, so as to play the role of early warning. The study result can provide references for the study on the early warning of pres- sure pipeline burst.
