The pilot study indicates that the PS wave amplitude anomaly will hopefully be a convincing criterion to detect fissure zone.
初步研究表明，PS波振幅异常有望成为强裂隙探测的有力判据。

Based on the mechanism of input and damping, it is suggested that the vibration amplitude and threshold be taken as a criterion for evaluation vibration strength and anti-vibration ability.
Found non-linear fatigue damage equation and fatigue failure criterion of concrete under variable amplitude load, and analyze the influence of loading sequence on total fatigue life;
