摘　　要：随着一些大城市建设大型长距离输水管,在沿途人口稠密区的爆管可能引发次生灾害而成为棘手问题。及时发现输水管爆漏强度和地点,迅速采取应急措施,是降低爆管灾害的重要条件。提出了沿线实时测压法监测输水管爆漏,能够在3～5 min内对1%爆漏量报警,并提供爆漏点和爆漏量等信息。利用该方法还可以分析输水管是否存在泄漏、淤塞、粗糙度增加等问题,提高了科学管理水平。With construction of large-scale and long-distance water transmission pipelines in large cities, it is a thorny issue that the pipe burst can trigger secondary disasters in the densely populated areas. Timely detecting the bursting strength and location of leaked pipes and rapidly taking emergency measures are so important for reducing disasters. The real-time manometry is proposed for the burst leakage monitoring along the pipelines. It can alarm timely within 3 to 5 min when the burst leakage amount is up to 1% , and provide some information such as the burst leakage location and the burst leakage amount. This method can analyze the existence of water pipes leak, blockage, roughness increase and other issues to improve the scientific management level.
