With the rapid development of infrastructure projects in China, the use of anchor bolts in mining, geology, and tunnel engineering continues to increase. The non-destructive testing of anchor bolt quality is crucial for enhancing the stability and safety of engineering projects. Based on the stress wave detection method, wavelet threshold functions and STA/LTA algorithms were employed to comprehensively evaluate anchor bolt engineering. A software for non-destructive testing and intelligent analysis of anchor bolt anchorage was developed, integrating signal filtering and acquisition of anchorage parameters. Through numerical simulation analysis of anchor bolt anchorage, the lengths of anchor bolts were calculated using both manual picking and software-based arrival time extraction. The results show that the software-calculated anchor bolt lengths have an overall error controlled within 5%, offering higher precision than manual picking, which is significant for improving the safety and stability of project engineering.

随着中国基础建设事业的迅猛发展,锚杆锚固在矿业、地质、隧道等工程上的使用量不断攀升,锚杆锚固质量的无损检测对于提高工程项目稳定安全具有重要意义。因此,以应力波检测法为基础,运用小波阈值函数、STA/LTA等算法,对锚杆工程进行综合评价,设计开发出集信号滤波、锚杆锚固参数获取等功能为一体的锚杆锚固无损检测与智能分析软件。通过锚杆锚固数值模拟分析,分别计算人工拾取和软件到时提取的锚杆长度,得出软件计算出的锚杆长度总体误差控制在5%之内,比人工拾取精度更高,对于提高项目工程安全稳定具有重要意义。
