Based on the one-dimensional wave theory, nondestructive testing with stress wave reflection method bolts is a kind of quick and effective detection method; the method was used to estimates the anchorage quality according to some parameters such as waveform, phase, amplitude, frequency as well as arrival time of both the incident wave and the reflected wave; stress wave velocity is the basic parameter for quality assessment, the velocity is depended on signal identification of the integrity bolts, especially the reflected ones from the bottom. This paper, through the transient dynamic response...
