In order to testing bolts in concrete quickly and effectively, an experiment was conducted to study the transient dynamic response on bolts in concrete based on the stress wave reflection method. The waveform characteristic of acceleration response curves for free bolt, integrated bolt, and defective bolts with different compactness was analyzed and the anchorage integrity of defective bolts with different compactness evaluated. The results show that the waveform of the free bolt is very regular, the attenuation degree of stress is slight while the multiple bottom reflection is very obvious; i...
