摘　　要：简单介绍声发射技术的定义与原理,在对国内外相关文献进行分类、归纳和总结的基础上,从桥梁工程、水利和岩土工程、建筑工程以及其他特种工程4个方面综述了声发射技术在土木工程相关领域中的应用现状和研究进展,总结了该领域的研究热点,并就声发射技术的发展前景和需要进一步研究的问题提出了自己的看法。Acoustic emission, applied in the field of civil engineering and life assessment of safety monitoring, is a real-time, dynamic, nondestructive testing technology. This paper briefly introduces the definition and principle of acoustic emission technique. Based on classification and summary of the domestic and foreign literature, the key issues, research status, and progress of this technique are reviewed from four aspects： bridge engineering, geotechnical and underground engineering, hydraulic engineering, and other special engineering. Finally, the authors put forward their own opinions on the prospects of this technique and problems that need to be investigated in the future.
