摘　　要：基于声波法的管道泄漏检测技术因其灵敏度高、定位精度高、可长期使用等优势近年来成为研究热点。阐述基于声波法的泄漏检测原理,采用文献计量学方法统计分析了2020—2021年该领域的文献类型、发文量及关键词,通过文献可视化分析软件VOSviewer进行关键词共现,分析得到该领域的热门研究方向及其热点技术,对其研究现状进行综述,并对未来发展趋势进行了展望。结果表明:基于声波法的管道泄漏检测技术领域的文章发文量呈逐年上升趋势,泄漏声波产生机理、声波传播与衰减特性、泄漏声波信号处理方法为该领域3个主要研究方向;其中泄漏声波信号处理方法众多且各有优缺点,次声波信号因其传播距离长、能量损失小等优点成为该方向的研究热点。未来应针对液体管道非满管情况泄漏检测、气液混相管道泄漏检测及两种工况对应的声波衰减模型构建开展攻关研究。(图4,表1,参57)Pipeline leakage detection technology based on acoustic wave method has become a research hotspot in recent years because of its advantages like high detection sensitivity, high positioning accuracy, and long-term service. The principle of leakage detection based on the acoustic wave method was expounded, the type and the number of published papers and keywords in this field from 2020 to 2021 was statistically analyzed with the bibliometric method, and the keywords co-occurrence was analyzed by visual analysis software VOSviewer. Then the research status of popular research directions and hot technology were reviewed, and the future development trend was prospected. The results show that the number of published papers in the field of pipeline leakage detection technology based on acoustic wave method is increasing year by year, and the generation mechanism of leakage acoustic wave, the acoustic wave transmission and attenuation characteristics, and the signal processing of leakage acoustic wave, were the three main research directions in this field. There are many signal processing methods, which have their own advantages and disadvantages, and the infrasonic signal has become a research hotspot because of its advantages, such as long transmission distance and small energy loss. In the future, research should be carried out on leakage detection of liquid pipeline under non-full condition, leakage detection of gas-liquid mixed phase pipeline and modeling of acoustic attenuation corresponding to these two working conditions.(4 Figures, 1 Table, 57 References)
