本文从完善锚杆锚固质量检测体系出发,提出以可控震源技术实现对应力波信号的精确控制,并调制出具有良好自相关性的Chirp信号作为震源信号。借助自主开发的Delphi应用程序,笔者实现了多种检测信号,并对信号的频带、自相关特性等特点进行了对比研究,结果证明Chirp信号非常适合于作为锚杆质量检测信号,而且可控震源技术的实现也必然引发锚杆质量检测精度的大幅提高。 In this paper, based on improving the detection system of anchor bolt anchorage, the control of stress wave signal with vibroseis technology is proposed and the Chirp signal with good autocorrelation is modulated as the source signal. With self-developed Delphi application program, the author realized a variety of detection signals, and compared the characteristics of the signal band, autocorrelation characteristics and other results. The results show that the Chirp signal is very suitable as a signal for the detection of bolt quality, and vibrator The realization of technology will inevitably lead to a substantial increase in the accuracy of bolt quality inspection.
