摘    要:声发射技术已经应用于金属和混凝土结构中,作为探测内部裂缝的一种无损检测方法。目前用的技术都是由压电换能器来采集声发射信号。讨论了基于用光纤技术的声发射传感器的开发和测量方法。它是用埋入式光纤传感器来监测类似桥梁、高速公路、隧道和房屋建筑等混凝土结构中的开裂信号。

关 键 词:声发射  无损检测  建筑结构  埋入式光纤传感器

Abstract:Acoustic emission (AE) technique has been applied to metallic and concrete structures as a nondestructive testing (NDT) method for detection of internal cracks. Current techniques employ PZT transducers for acquisition of AE signal. The work presented here describes development and testing of an AE sensor based on the optical fiber technology. It can monitor the crack signal in the concrete structure, for example, bridge, highway, tunnel and building etc., using the embedded optical fiber sensor.
Keywords:acoustic emission    optical fiber sensor    nondestructive testing
