MATLAB环境下频域分析在工程锚杆无损检测中的应用

Frequency-domain Analysis in NDT of Engineering Anchors in MATLAB

随着锚杆锚固技术在世界各地岩土工程中越来越广泛的应用,锚杆锚固工程质量问题时有发生,因此,对锚杆的检测工作就显得极其重要.以某工程为实例,分别采集完整锚杆和缺陷锚杆的时域和频域信号,进行对比结果分析,得出频域分析可作为锚杆缺陷识别判断的依据.

With the wider application in the geotechnical engineering of anchorage technique of anchors in the world,anchorage problems has been happening at all times,so the examination to the anchors seems to be very important.Taking a project as an example,the time-domain and frequency domain signals from defective anchor poles and good anchor poles were respectively collected,and comparing the results of analysis,the frequency-domain analysis can be used as a basis for judging the defects of engineering anchors.
