摘要
为确定声发射源定位技术在混凝土检测中的精度,同时验证所采用的声发射检测参数值的合理性。通过3D定位法分析了混凝土中心拔出试件在粘结破坏过程中试件内部缺陷源发展情况。分析结果与实际情况相吻合,所采用的声发射参数设置值使源定位获得了较高的精度。
In order to know source location precision of AE technique and validate the rationality of the setting of AE detecting parameter value in concrete detection, inner defects in pull-out samples during bond damage was analyzed by 3D location method. Compared with practical results, reasonable analysis results were gained. Highly precise source location was gotten with detecting parameter value adopted in this paper.
