摘　　要：为提高管网检漏及维修能力,对管道漏水时声音传播的距离及振动强度进行分析。在不同的深度、压力下,声音传播的变化不同,利用听音法等检测方法准确找出漏水点位置,降低漏水量。通过文中叙述的几种方法进行查找,保证了管网漏水率在国家标准范围内。In order to improve the ability of leakage detection and maintenance,we analyzed the distance of sound propagation and vibration intensity when the pipeline had leakage. According to the variation of sound propagation under different depth and pressure,listening and other detection methods can be used to accurately locate the leakage point and further reduce the leakage.Through several methods described in this paper,leakage rate of pipe network can be ensured to be within the scope of national standard. The leakage rate of the pipe network can be controlled within the scope of the national standard by the methods of leakage detection described in this paper.
