摘　　要：我国水资源人均占有量仅为世界的1/4,给水管道泄漏造成的损失,不仅加剧了我国水资源浪费,造成经济损失,还将带来社会问题。给水管道漏损问题作为供水行业普遍存在的现象,已引起各国的普遍关注。简要介绍国内外给水管道漏损情况及可能引发的危害,综合分析管道漏损的原因。在众多检漏技术中,重点介绍声学在给水管道检漏技术中的应用,通过对声波检漏技术的原理进行分类,简述给水管道检漏技术现状及最新技术。最后指出当前检漏技术存在的问题,为声学在给水管道检漏中的研究提供参考。Water resources per capita in our country only accounts one quarter of world's average level.Leakage in water supply pipelines not only intensifies the waste of water resources,results in economic losses,but also brings about social problems.The issue of water supply pipe leakage is a common phenomenon in the water supply industry and has aroused widespread concern in many countries.In order to solve the problems,a closer look into the current situation of water supply pipeline leakage around the world is needed.The hazards that come along will be introduced briefly.Besides,a comprehensive description of leakage reasons in the pipelines will also be presented.Among the many detection technologies in water supply pipelines,great emphasis on acoustic technology is placed.To point it out,the acoustic technology is classified into several different categories according to different principles.The most important part is the present situations of the acoustic leakage detection technologies.At the same time,the latest technologies in the field of acoustic detection are also given out.In the end,the existing problems are pointed out and several personal opinions for future development in the study of acoustic technology are proposed in leakage detection of water supply pipelines.
