声发射技术在水电工程安全监测中的应用

Application of Acoustic Emission Technology in Safety Monitoring of Hydropower Project

声发射技术已广泛应用于航空航天、机械加工等领域,但在水电工程安全监测领域却应用较少。本文介绍了声发射技术的原理及特点,声发射检测系统的组成、功能要求和基本应用,并以三峡双线五级船闸高边坡岩体成功采用声发射监测技术为例,说明该技术在水电工程安全监测中具有广阔的发展前景。

Acoustic emission technique has been widely used in aerospace, machinery processing and other fields, but the application in the field of hydropower engineering safety monitoring is less than possible. This pa per introduces the principle and characteristics of acoustic emission technology, composition, function and basic application of acoustic emission testing system, and the Three Gorges two way five on high slope rock mass sue cessfully using acoustic emission monitoring technology as an example. This technology has broadened develop ment prospects in safety monitoring in hydropower engineering.
