桥梁锚具为厚壁曲率构件,具有明显的各向异性,超声检测时容易产生衰减增加、波束偏移等现象。超声相控阵利用声束控制技术,实现对锚具的多角度、多方位的扫查,对疏松、裂纹等缺陷的检测结果表明,超声相控阵技术可有效地进行桥梁锚具的检测。 Bridge anchors are thick-walled curvature members with obvious anisotropy. When ultrasonic testing is carried out, the phenomenon of increased attenuation and beam offset is easy to occur. Ultrasonic phased array using sound beam control technology to achieve the multi-angle, multi-azimuth scan anchor, the detection of defects such as loose, cracks and other results show that ultrasonic phased array technology can effectively bridge anchors detection.
